WHY IS IT CALLED THE SLOWFIT METHOD®? (PART II)

And what exactly is it the antidote to?

Keir J Beadling

Jul 29, 2026

This is Part II in a series. Best to peruse Part I to catch up a bit, before moving on to this one. Then again, fine to read this one first. Regardless, I’m tackling the question of the name — Slowfit, and explaining why this whole thing is intended to empower you with agency. Choices that belong to you in terms of your health and happiness. All in the face of certain forces, some of which have just sort of happened as we’ve strayed from our evolutionary design in a modern world. And some others of these forces could justifiably be called dark forces. Forces incentivized by things different than the things that are good for you as a human being. I’d argue its important to understand the bigger picture and some common themes at play here, so that we can stand a chance against Big Food, Big Booze, Big Shoe, Big Tech, and the like. So that we can take back control of our lives and and actually flourish.

It starts with the name I chose. Slowfit.

I hear you, it’s different, a little counter-intuitive, even. Slow? I don’t want to be slow! Isn’t this the opposite of what a fitness brand should be called? Where’s the intensity? The urgency? The before-and-after? Fitness brands are supposed to promise fast. Six weeks! Twelve moves! One weird trick! No pain, no gain! Push harder! Do more! Sleep when you’re dead! Watch this 7-second video! Now this one! And this one! Stress? What stress?

That’s exactly the problem.

The Slowfit Method® is not slow in the sense that it is easy. It is slow in the sense that it is deliberate. Because the interventions that actually work are almost always the ones that take time, require consistency, and resist the cultural pressure to turn everything into a shortcut. It is slow the way a sequoia is slow. The way compound interest is slow. The way building a life you don’t need to escape from by eating something or drinking something or doom-scrolling something to distract you from this moment—is slow. Like slow food. Slow streets. Slow parenting. Slow cities.

Slowfit. Get it?

It is also, quite deliberately, the antidote to a very specific set of forces — forces that are working against your health, your performance, and your quality of life, right now, across every dimension simultaneously.

Here is what the Slowfit Method® is the antidote to. Pillar by pillar. There’s a lot to cover here, folks, so I split the topic into four parts. This one is Part II of IV. (Reminder: Part I lives here.)

Mouth breathing and over-breathing.

You take roughly 20,000 breaths a day. If you’re breathing through your mouth, shallowly, chaotically — which most people are — you are driving down your CO2 levels, undermining oxygen delivery to your tissues, elevating your cortisol, disrupting your sleep, and suppressing your immune function. Sending a signal of danger to your central nervous system, resulting in a state of chronic arousal. This is not a minor inconvenience. It is a systemic health failure happening 20,000 times a day. All stirred up by overreacting to that email, that text message, that news media alert, that guy who just cut you off in traffic…. We live in a culture of hyper-stimulation, and the vast majority of us are making it worse by reacting with over-breathing through the mouth.

The Slowfit antidote: nasal breathing, pretty much always. CO2 tolerance training. A downregulation protocol post-workout and before bed. The Wim Hof upregulation protocol before training. Paying attention to the breath constantly. Your breath is the only autonomic function you can also consciously control. Use it. Exercise agency over this moment, right here.

YOU TAKE 20,000 BREATHS A DAY. HERE’S WHY MOST OF THEM ARE WORKING AGAINST YOU.

At the end of the last post in this series — the Mindset pillar — I teased what was coming next.

Smartphone and social media addiction.

In Part I, I talked about Big Food, Big Booze & Big Shoe. Now we’re on to Big Tech. Adam Alter’s research in Irresistible documented the six ingredients that make behavioral experiences as addictive as heroin. In Screen People, Megan Garber warned what happens to a civilization that organizes itself around those ingredients. And in The Anxious Generation, Jonathon Haidt documented what happened to an entire generation of children. The variable reward schedule. The infinite scroll. The slot machine in your pocket, available 24 hours a day, engineered by people who understand the neuroscience of compulsion better than most psychiatrists.

The Slowfit antidote: intentional technology. Use the smartphone. Don’t be used by it. State a purpose before you open any app. Switch to greyscale. Tape your mouth at night and put your phone in another room (that sounds a little weird, but the taping is for improved nasal breathing, not to prevent you from talking on your phone—though I suppose that’s a nice side effect). Remember that your attention is the most valuable thing you own. Defend it accordingly. Don’t give it away to things that don’t deserve it. Again, agency. We have agency.

SAME PLAYBOOK. DIFFERENT INDUSTRY.

We made it! Ellie and I covered about 3,000 miles from one coast to another. Whew. A week behind the wheel offers up a fair amount of think time. And the next couple posts here will be a product of 48 hours in the driver’s seat and a lucky backlog of Audible credits.

Requiring constant stimulus. Being held hostage to a chronic state of arousal.

What might we call this one, Big Attention? Probably still Big Tech, for the most part. The modern attention economy has trained an entire population to be incapable of tolerating silence, stillness, or unstructured time. Standing in a line without checking a phone. Sitting with a thought without immediately reaching for distraction. Being in a beautiful place without photographing it for an audience. The inability to be present in a moment that isn’t performing for anyone is one of the most consequential health crises nobody is naming.

The Slowfit antidote: presence. Meditation. Long walks without AirPods. Books instead of feeds. The deliberate cultivation of your own inner life, which turns out to be where performance actually lives.

Meditation, for example, is backed by so much research now, folks. It’s a huge miss not to be doing this on the regular. I wrote about the benefits of a meditation practice here.

Across every Slowfit pillar, there is a version of the world that is working against you — a faster, louder, more addictive, more profitable version of health and fitness that extracts value from your attention and your body and returns chronic disease, fragmented focus, and a vague sense that something is wrong.

And across every pillar, there is a choice.

You can eat the food that was engineered to make you eat more of it. Or you can eat real food.

You can pour yourself a drink to numb the edges of your life. Or you can learn to be comfortable in your own skin.

You can breathe through your mouth, shallowly, without thinking. Or you can close your mouth.

You can let the back pocket slot machine rent your attention. Or you can be present in your own life.

You can run on the hedonic treadmill until your knees give out. Or you can find a reason.

You can outsource your social life to a platform. Or you can show up for the people in front of you.

You can grind yourself into cortisol-flooded exhaustion. Or you can dose yourself intelligently and recover like it matters.

You can live as though sleep is optional. Or you can train in your sleep.

That’s the Slowfit Method®. Not a program. Not a protocol. A framework for making the better choice, pillar by pillar, day by day, for as long as you’re here.

Slow. Deliberate. Yours.

Stay tuned for Part III.

People ask me about the name. Pretty much from the moment I suggested it, even. “Hey, whaddya think about Slowfit?”

Slowfit. It sounds like the opposite of what a fitness brand should be called. Where’s the intensity? The urgency? The before-and-after? Fitness brands are supposed to promise fast. Six weeks. Twelve moves. One weird trick. No pain, no gain. Push harder. Do more. Sleep when you’re dead.

That’s exactly the problem.

The Slowfit Method® is not slow because it is easy. It is slow because it is deliberate. Because the interventions that actually work are almost always the ones that take time, require consistency, and resist the cultural pressure to turn everything into a shortcut. It is slow the way a sequoia is slow. The way compound interest is slow. The way building a life you don’t need to escape from by eating something or drinking something or doing something to distract you from this moment—is slow.

Here is what the Slowfit Method® is the antidote to. Pillar by pillar. There’s a lot to cover here, folks, so I reckon I’ll split the topic into four parts. This here is Part I. Today we’re going to tackle Big Food, Big Booze and Big Shoe.

Ultra-processed food.

And I’m not just talking about Doritos. Sixty percent of the American diet is now engineered in laboratories to override your satiety signals and create compulsive, escalating consumption. Dr. Chris van Tulleken spent a month eating 80 percent ultra-processed food and watched his body and brain deteriorate in real time. Robert Lustig has spent decades documenting how the food industry deliberately conflated sugar with food and sold us chronic disease as a lifestyle. Herman Pontzer proved you cannot outrun a bad diet.

The Slowfit antidote: eat real f*cking food. Four words. OK, three if you take out that one I put in there for extra oomph. Bottom line is, if your great-grandparents wouldn’t recognize it as food, it probably isn’t.

EAT REAL FOOD. THE REST IS DETAILS.

The Joy Juice.

The alcohol industry has spent decades and billions of dollars convincing you of two things that are not true. First, that moderate alcohol consumption is good for your health — a claim built on deeply flawed observational studies that the industry helped fund and promote. Second, that a fulfilling life — celebration, connection, relaxation, reward — requires their product to be complete.

Neither is true. Both are manipulations.

The U.S. Surgeon General issued an advisory in January 2025 declaring alcohol the third leading preventable cause of cancer in the United States. Not a risk factor. The third leading preventable cause. So why would I want to put that into my body? On purpose? The science has been available for years. The wine industry’s Mediterranean diet talking points, the beer commercials that make you believe every meaningful human moment requires a cold one, the social script that frames sobriety as joylessness — all of it is marketing. Great marketing, too. This Bud’s for you! Weekends are made for Michelob! Tastes great, less filling! Stay thirst, my friends! These ad agencies have earned their huge fees. I am as entertained as anyone by the Super Bowl halftime ads. Alas, none of it is medicine. None of it.

But the manipulation goes deeper than the carcinogen. Alcohol is also one of the most effective tools available for avoiding yourself. For numbing the discomfort that is actually information. For suppressing the low-grade anxiety that, if you sat with it, might tell you something important about your life. A drink to take the edge off. Another to get to sleep. A third because the first two didn’t quite do what you needed. The hedonic treadmill running at full speed, tolerance building, the dose escalating to maintain the same effect.

This was a big one for me. Not drinking myself into oblivion. But rather, using a big IPA or two to get my brain to slow down. Guys, there’s a better way. Lots of better ways, actually.

I get it. Learning to be comfortable in your own skin — present, unmedicated, in the actual texture of your life without a chemical buffer — is hard. It is also one of the most important things you can do for yourself. William Porter’s Alcohol Explained is the clearest account I’ve read of why alcohol makes you feel better in the short term and worse in every other dimension. Annie Grace’s This Naked Mind is the best account of how to understand the grip it has and decide for yourself whether to let go of it.

I’ll be four years sober in October. Not because I had a problem by conventional definitions. Because the data was unambiguous — my sleep, my recovery, my HRV, my cortisol, my cognitive clarity all improved materially and measurably. A drink or two on a Friday night was affecting my Tuesday training. The trade was not worth it.

The Slowfit antidote: honesty. Not prohibition — agency. Look at what alcohol is actually doing to your body and your mind, strip away the marketing, and make a real choice. Your own choice. Not one foisted upon you by Madison Avenue. A fulfilling life does not require poisoning yourself with a known carcinogen while bowing to television advertisements. It just doesn’t.

Chronic cardio.

So far we’ve got Big Food, Big Booze & now, Big Shoe. You’re likely familiar with the hedonic treadmill? On this point here, I’m referring to the treadmill treadmill. Mark Sisson has written compellingly about what he calls “chronic cardio” — the kind of punishing, high-volume endurance training that grinds the body into a cortisol-flooded state of permanent, low-grade stress. Long-distance running done at the wrong intensities, day after day, without adequate recovery, doesn’t make you fitter. It makes you sick, injured, and inflamed.

All aided by the shoe companies who have propagandized us for years with overly-cushioned shoes featuring narrow toe boxes and raised heels. Shoe coffins.

Been there, done that. I remember running my first marathon—don’t get too excited, I only did a few of them. The Boston Marathon in 1995 or maybe 1996. (No, I didn’t qualify for this one—I had a buddy with some graphic design bona fides and morals as bent as mine whip up a counterfeit race bib, but that is another story altogether). I trained in “motion control” shoes through regular bouts of shin splints that left my lower legs painful to the touch. In an incredibly dumb bout of pre-race exuberance, I ran a race-pace 8 miles a couple days before the marathon itself.

I also remember being deep into training for my first Ironman-distance triathlon (again, not a humble brag, I didn’t do many of these), while running a 6-week jury trial as an overly ambitious young litigator, just 2 weeks before getting married. In what world is any of that a good idea?

Thankfully, I know better now (because…science).

The Slowfit antidote? Smart dosing. Zone 2 for your aerobic base. Brief, intense efforts for VO2 max. Strength work twice a week. And recovery treated as part of the training — not what happens when you’re too tired to train. A viable longevity strategy should involve regular walking, rather than running yourself into the ground. Oh, and ditch the shoe coffins. Gradually, like any other big change. But get thee some shoes that reflect what our feet are designed to do—toe-splay, perceive the ground, no high heels.

The Month Cartilage Science Changed Everything — And What It Means For Your Knees Right Now

July 8, 2026human performancearthritis, artificial intelligence, exercise, fitness, Health, human performance, knee osteoarthritis, mental-health, personal training, shotokan karate, Triathlon, wellnesskjbeadling Leave a comment

A few weeks ago I wrote about my own knee osteoarthritis diagnosis — the swollen left knee that wouldn’t quit, the 30cc of fluid my orthopedic surgeon’s staff drained in his office, the Baker’s cyst, the MRI findings, the cortisone shot, the pending hyaluronic acid injection series. I promised updates as things developed.

Here’s the update: I just completed a multi-day karate special training. Strenuous, demanding, the kind of training that tests your entire body and your mind in equal measure. My knee is still not perfect. The inflammation is ongoing. And I did it anyway — not because I was reckless, but because the emerging science told me I should. And because I’m in the business of continuing to do the things that I love, that give my life meaning.

How Seven Principles Changed the Way I Built My AI Coaching App

June 20, 2026Healthai coaching, artificial intelligence, coaching, Health, human performance, mental-health, personal-training, san francisco, Triathlon, wellnesskjbeadling Leave a comment

The Center for Humane Technology had a lot to do with it.

I’ve been following Tristan Harris and Aza Raskin at the Center for Humane Technology for years. If you’ve seen The Social Dilemma on Netflix, you know Tristan’s face and his argument: the tech companies that run our lives are not neutral platforms. They’re slot machines, engineered by very smart, very well-funded people to maximize one thing above all else. Not your health. Not your relationships. Not your sleep. Your time on device.

That argument is not new to regular Foghorn Fitness readers. I’ve written about it at length. The distraction pillars. The phone breakup series. The Johann Hari and Jonathan Haidt posts. I’ve been making the case for years that your smartphone is doing things to your attention, your sleep, your nervous system, and your relationships that you haven’t consented to and probably don’t fully understand.

And then I built an app.

Wait, what?

I know. We’ve been over this. And a podcast episode I listened to yesterday clarified things for me in a way I hadn’t expected. CHT just released a new Your Undivided Attention episode in which Aza Raskin sits down with fellow CHT co-founder Randy Fernando to walk through their Seven Principles of Humane Technology. I want to take you through those principles — and then show you, specifically, how each one maps to the design decisions I made building the Slowfit Method® app.

Because this isn’t abstract. Every one of these principles shows up in the product.

First: What’s Actually Wrong With Most Tech

The episode opens with a clip from CHT’s very first podcast guest, cultural anthropologist Natasha Dow Schüll, who spent years studying casino design in Las Vegas. What she observed is the design logic behind modern slot machines: the goal is “time on device.” Everything is engineered to eliminate fatigue, minimize disruption, and keep you in the chair. Light doesn’t bounce at your eyes. Sound doesn’t jar your senses. The environment is calibrated to sustain your engagement indefinitely.

Raskin’s point: that’s exactly how your apps are designed. Not for your wellbeing. For time on device. Instagram, TikTok, YouTube, the news feed — different technologies, same broken ideology.

Raskin himself invented the infinite scroll, pre-social media. He watched it get weaponized against users and has spent the past decade trying to undo the damage. He estimates it wastes something on the order of 100,000 human lifetimes every week.

That’s the problem CHT’s seven principles are designed to solve. Here they are — and here’s how I applied each one.

Principle 1: Use a Complex Systems Lens

One of the big things that we miss a lot when we are dealing with technology is we don’t look at the whole system. We look at just one small piece of it and that means we don’t correctly understand what its effects are going to be and we don’t correctly understand how to fix the problems that we find. — Randy Fernando

The failure mode Fernando describes is optimizing for a single metric — engagement, time on site, daily active users — while ignoring what that metric does to everything else. YouTube optimized for watch time. The result was algorithmic extremism. You can’t see the damage from inside the single metric. You need to look at the whole system.

In the Slowfit Method® app, I deliberately refused to build around a single engagement metric. There are no daily active user dashboards driving product decisions. There are no A/B tests designed to squeeze more sessions out of users. The question I kept asking during development was not “how do we get people to come back?” It was: “what does a successful interaction actually look like?” The answer: the user got what they needed and went and did “the thing.” That’s the whole system I was trying to optimize for.

Principle 2: Protect the Systems We All Depend On

If you extract faster than something can regenerate, obviously that’s a problem. Technology is a huge exponentiator of that extraction process. — Randy Fernando

Fernando’s framework here is extraction vs. regeneration. Most tech extracts — attention, time, data, dopamine — faster than humans can regenerate. The result is depletion. Of attention spans. Of sleep. Of real-world relationships. Of the shared information environment we all depend on for democracy to function.

The Slowfit Method® is built around the opposite premise. Sleep, recovery, social connection, movement, mindfulness — every pillar is about replenishment, not extraction. I tried to build an app that reflects that. An hour on the app is an hour less of the things that regenerate you. So the app shouldn’t take an hour. It should take two minutes and send you back to the things that do.

Principle 3: Design for Genuine Thriving

A tool that’s designed for genuine human thriving will leave you stronger when you put it down than when you picked it up. — Aza Raskin

This is the principle most directly tied to the experience of using technology. Raskin puts it simply: when you put your phone down after an hour on it, do you feel better or worse? When you wake up the morning after a late-night scroll session, do you feel better or worse?

Fernando connects the anti-AI sentiment building in the culture to this principle’s absence. Students booing AI at commencement speeches. Parents pulling kids off platforms. Communities organizing against data centers. That resistance isn’t coming from people who’ve read ethics papers. It’s coming from people who can genuinely feel that something is wrong.

What they’re feeling, Fernando argues, is the absence of this principle. Technology built to extract attention, replace labor, and harvest data rather than to genuinely serve the humans using it.

When I designed the Coach Keir AI interface, I wrote this into the system prompt: the AI should never try to extend the conversation beyond what’s useful. It should give direct answers. It should end responses with a single action item. It should tell you to put the phone down. Literally. You saw the screenshot in an earlier post: “Your move: Phone face down across the room. Lights out. Start breathing.” That’s designing for genuine thriving.

Principle 4: Align Incentives with Human Wellbeing

The fourth principle is about business models. Most tech companies have a fundamental misalignment: they make money when you use the product more, not when you’re healthier, better rested, or more connected to the people in your actual life. That misalignment is structural. It’s not fixed by good intentions. It’s fixed by changing the incentive.

The Slowfit Method® app runs on a subscription model. I make money when people find enough value to pay for ongoing access to the Vault — 270+ books, podcasts, tools, and on-demand workouts — not when they spend more time banging around for hours in the chat interface. That changes what I’m actually optimizing for. I want the free Coach Keir AI interactions to be so useful and so direct that people think “this person’s deeper knowledge base is worth paying for.” Not “I can’t stop using this.”

Principle 5: Foster Autonomy and Agency

Inhumane tech exploits psychological vulnerabilities. Variable reward schedules. Social comparison. FOMO. The fear of missing out on what everyone else is seeing right now. These are not neutral design choices. They are deliberate mechanisms for hijacking your decision-making and substituting the algorithm’s agenda for your own.

I built the anti-version of this into every layer of the app. No infinite scroll. No push notifications designed to pull you back. No streak mechanics that make you feel bad for not opening the app three days in a row. No social comparison features. The Coach Keir AI is explicitly designed to be anti-sycophantic — it will tell you what you need to hear, not what you want to hear. Autonomy means you get accurate information and make your own decisions. That’s what I want the app to support.

Principle 6: Ensure Accountability and Transparency

This one is personal. When you open the Coach Keir AI, the first thing you see is a banner: “AI-generated responses. Coach Keir AI is not a licensed medical professional. Emergencies: 911. Mental health crisis: call/text 988.”

That’s not a legal disclaimer buried in the terms of service. That’s the first thing you see, every time, in the primary interface. Because transparency about what the technology is and isn’t matters. The AI is trained on my writing and my methodology. But it is not me. It is not a therapist. It is not a doctor. It is a tool. I wanted users to know that before they typed their first message.

I also published Substack posts about the app’s design philosophy before and again after I published anything about its features. One about why I built it to not be addictive. Another about the ethical decisions baked into the system prompt: the anti-sycophancy rule, the distress routing protocol, the nudge toward real human coaching. Accountability means making those decisions visible, not hiding them in the product.

Principle 7: Build for the Long Term

The final principle is the hardest one for most tech companies because the market actively punishes it. Fernando uses car safety as his example: the automakers weren’t excited about investing in safety until cultural pressure, regulation, and changed incentives forced them to. The same transformation needs to happen in tech.

I think about this principle in terms of the Slowfit Method® itself. The whole framework is built around the long game. Not the fastest result, the best result over time. Not maximum intensity, optimal sustainable load. Not the biggest Strain Score number on your Whoop this week, the best recovery over the next twenty years.

The app is an expression of that philosophy. I’m not trying to maximize short-term engagement metrics. I’m trying to build something that is genuinely useful to people over time. Something that, in a year, someone might say: that app didn’t try to take over my life. It helped me understand mine a little better. Actually helped me improve things. And then it got out of the way.

Why This Matters Right Now

I am not under any illusion that a single human performance coach bumping along towards 100 app downloads over two weeks in San Francisco is going to single-handedly reform the tech industry. That’s not the point.

The point is that the principles exist. They’re not idealistic. They’re not impractical. They’re a checklist that any builder of any product — at any scale — can apply. And I applied them. Imperfectly, with limited resources, in a space dominated by products that ignore all seven.

Raskin ended the episode with something that stuck with me. He said you know a system is humane when it is protecting the thing that it depends on. Ask yourself: has social media made democracy stronger or weaker? Has the infinite scroll made your attention stronger or weaker? Has the algorithm made your relationships stronger or weaker?

The answers are obvious.

Now, after spending a little time kicking the tires on my little app, ask: has the Slowfit Method® made my health stronger or weaker? Has Coach Keir AI made my sleep better or worse? Has this app left me more capable or less?

Those are the right questions. They’re the only questions, I’d say. I hope you’ll make a little bit of space in your life for this app. I promise it’ll help.

And maybe go listen to the Your Undivided Attention episode. It’s 52 minutes and it’s worth every one of them.

Stick around.

Best,

Keir

The App I Built Is the Opposite of Everything I’ve Been Warning You About

“This phone is the devil”

— a childhood friend, via text, this morning

He’s getting off Instagram. Can’t say I blame him.

I’ve spent years writing about your phone. Specifically, about what it’s doing to you. (And to me.)

In January 2024 I wrote about Johann Hari’s Stolen Focus and the trillions of dollars arrayed against your ability to pay attention. In February 2024 I went deeper on why it’s so hard to focus — the dopamine dependency, the slot-machine mechanics, the infinite scroll engineered to exploit our evolutionary hard-wiring. In October 2024 I wrote about Jonathan Haidt’s The Anxious Generation and what the smartphone has done to our kids. And before all of that, Cal Newport’s Digital Minimalism convinced me to deliberately downsize my iPhone use, strip the social media icons off my home screen, and mute the notifications pulling my attention toward that hunk of plastic and glass in my pocket.

The research is clear. Maggie Jackson, in Distracted, put it as starkly as anyone: with our attention scattered among the beeps and pings of a push-button world, we are cultivating a culture of distraction and detachment.

I didn’t just write about this stuff. I lived it. A while back I documented my own month-long attempt to break up with my iPhone — the rubber band around the phone, the grayscale screen mode, a Giants game where I didn’t look at a screen once (one of my prouder moments). The whole messy field report is in the Phone Breakup series if you want to go down that rabbit hole. The short version: it’s hard, it’s worth it, and I failed more than I succeeded. But I kept trying.

And then I went and built an app.

I know.

Here’s the Thing I Had to Reconcile

When I first started thinking seriously about building the Coach Keir AI app, I had a problem. Not a technical problem — that was my developer Alex’s department. Rather, I had to address a philosophical one.

I had spent years making the case that our smartphones are attention-harvesting machines designed by very smart, very well-funded people to keep us glued to screens as long as humanly possible. I had written about Anna Lembke’s Dopamine Nation and the way pleasure-seeking loops get forged into deep neural grooves. I had cited the Center for Humane Technology and Tristan Harris’ warnings about what engagement-maximizing technology is doing to human cognition. I had recommended Catherine Price’s How to Break Up with Your Phone to pretty much every athlete I coach.

And I was about to add another app to the App Store?

The only way I could do it in good conscience was to build the opposite of what everyone else was building.

So that’s what I did.

What “The Opposite” Actually Looks Like

No infinite scroll. No push notifications engineered to pull you back. No streaks. No engagement metrics. No algorithmic filler designed to keep your eyes on the screen.

The app gives you what you need and sends you back to your life. That’s the design spec. Use it as a springboard, not a slot machine. Remember Patagonia’s famous “Don’t Buy This Jacket” ad in The New York Times? Same energy. I want you to use this app. I also want you to use it for two minutes and then go to sleep.

Speaking of sleep.

Meet “Julie”

One of my longtime Foghorn athletes — I’ll call her Julie — has a bedtime habit that will be familiar to a lot of you.

She gets into bed at 10:30. She picks up her phone to “check one thing.” An hour later she’s still on Instagram, heart rate quietly elevated, nervous system humming, cortisol doing what cortisol does when you’ve been consuming a high-speed feed of other people’s highlight reels for 60 consecutive minutes. She falls asleep somewhere around midnight. Her Whoop recovery score the next morning is dismal. She’s groggy, short-tempered, and reaching for an extra cup of coffee by 9 a.m.

We’ve talked about this in our sessions. A lot. She knows the science. She’s read the posts I’ve sent her. She knows that the blue light from her phone suppresses melatonin, that the emotional arousal of social media keeps her sympathetic nervous system activated exactly when she needs to be downregulating, that the unpredictable reward schedule of Instagram is the same mechanism that keeps people at slot machines.

Knowing isn’t the same as doing.

So a couple weeks ago I told her to try something different. Instead of reaching for Instagram when she gets into bed, open the Coach Keir AI app and type in what she’s feeling.

Here’s exactly what Coach Keir said:

Julie, put the phone down right now. Instagram at 10:30pm is gasoline on the anxiety fire — the algorithm is literally designed to keep your nervous system activated. I know it feels like comfort but it’s the opposite.

Here’s your downregulation breathing protocol. Do this right now: Close your mouth. Keep it closed throughout. Start with a quick body scan from head to toe — wherever you find tension (jaw, shoulders, chest), let it dissolve on your exhales. Now breathe:

• 4 counts in through your nose, belly-led

• 8 counts out through your nose, slow and controlled

• No aggressive pauses, circular and gentle

• When your mind wanders to work anxiety, gently bring it back without judgment — no self-criticism, just return to the breath. The extended exhale is the physiological key — it directly activates your parasympathetic nervous system. Your body cannot stay in fight-or-flight with a long nasal exhale. This isn’t woo, it’s autonomic nervous system science. Do this for 5 minutes. Then finish with one big inhale all the way to the top, slight hold, then the longest possible nasal exhale you can sustain. That final exhale is your reset.

One more thing: If you want guided support for this, Headspace has excellent sleep meditations that pair perfectly with this protocol. It’s the only meditation app I use and endorse. Your move: Phone face down across the room. Lights out. Start breathing. You’ve got this Julie. Goodnight.

Two minutes to read that. Five minutes to do the breathing. She was asleep by 10:45. That’s not a miracle. That’s a tool.

The Irony Is Intentional

Yes, this requires using a phone to stop using a phone. I get it. That’s a real tension and I won’t pretend otherwise.

But here’s what I’d offer: the problem was never the device. It’s what the device is typically used for. Instagram, TikTok, and the news feed are engineered for maximum engagement. A breathing protocol is not. One is a slot machine. The other is a tool.

Catherine Price’s framework — ask yourself “What for? Why now? What else?” before you reach for your phone — is the right instinct. Most of the time, the answer to those three questions is damning. But occasionally the answer is: I need a downregulation protocol so I can sleep. And for that, a phone can actually help.

The Slowfit Method® has always been about intentional choices. Being deliberate about how and why we are living our lives, rather than just pouring more water into a glass that is already overflowing and hoping for the best. The app is the method in your pocket. Use it intentionally. For two minutes. Then put it down.

That’s the whole pitch.

What “Julie” Said Last Week

“Honestly? I forget sometimes and I end up on Instagram anyway. But when I remember to open the app instead, I’m asleep in under 15 minutes. When I don’t, I’m awake until midnight and I hate myself a little.”

Not a case study. Not a controlled trial. Just a Foghorn athlete who found one thing that works slightly better than the thing that wasn’t working.

Which is more or less what the Slowfit Method® is for.

My buddy from childhood is getting off Instagram. Good for him.

The phone doesn’t have to be the devil. But it’s up to us to make sure it isn’t.

Stick around.

Best,

Keir

I Asked My Own App for Help. Here’s What It Said.

June 17, 2026parenting tipsartificial intelligence, dogs, Health, human performance, life, mental-health, parenting, puppy, san francisco, sleep, vibe-coding, wellnesskjbeadling Leave a comment

A dispatch from the edge of new puppy ownership.

It is 8 a.m. I have already been awake for hours.

Meet Ellie. She is a puppy. She is adorable.

She is destroying me.

I want to be clear about something. I am a human performance coach. I have spent years building a ten-pillar framework for maximizing health and happiness. I teach people how to manage stress, optimize sleep, build resilience, regulate their nervous systems. I have a registered trademark, for crissakes.

And I am currently being defeated by a creature who weighs less than my lightest kettlebell.

So I did what I’ve been encouraging all of you to do. I opened the Coach Keir AI app and typed in my problem.

“I’m struggling with the stress of parenting a new puppy as a full time job, on top of my full time job.”

I want to share exactly what it said. Verbatim. Because it’s better than anything I would have written at that hour…

What Coach Keir Said: Round One

The first response named what was actually happening:

KJ, welcome to the puppy tax — the hidden cost nobody warns you about. Sleepless nights, constant vigilance, zero personal space, and a tiny furry creature who has absolutely no idea what you’re going through. It’s basically a newborn who will eventually chew your furniture.

Here’s what’s actually happening physiologically: you’re running a chronic stress response. Interrupted sleep alone tanks your cortisol regulation, impairs decision-making, and reduces emotional resilience. Add constant unpredictability (will she destroy something while I’m on this Zoom call?) and your nervous system is on high alert all day. That’s exhausting.

Immediate tools from the Slowfit toolkit:

First, your breathing. When the puppy stress spikes, do a quick downregulation reset: mouth closed, 4-count nasal inhale, 8-count nasal exhale. Repeat for 3-5 minutes. That extended exhale is a direct dial into your parasympathetic nervous system — it physiologically cannot stay in fight-or-flight mode with a long exhale. Do this during any quiet moment, even while the puppy naps.

Second, protect your sleep ruthlessly. Also grab a Manta Sleep mask with this link — blackout sleep is non-negotiable when you’re already sleep-deprived.

Your move today: Do that breathing protocol right now, then schedule one 20-minute walk — just you, no puppy. Your nervous system needs a reset.

What’s hitting hardest — the sleep deprivation or the constant unpredictability?

I answered: the sleep deprivation. And the follow-up was even better.

Round Two: The Neuroscience of Running on Empty

KJ, what you’re describing is textbook — and it’s not a character flaw, it’s neuroscience. Sleep deprivation doesn’t just make you tired, it literally impairs your prefrontal cortex (the rational decision-making part of your brain) while simultaneously amplifying your amygdala (the emotional alarm system). You’re essentially driving with no brakes and a heavy accelerator.

Dr. Lisa Feldman Barrett’s work is essential here — her book How Emotions Are Made explains exactly what’s happening to you. Her “body budget” model is brilliant: sleep, nutrition, exercise, and social connection are the bedrock of emotional stability. When sleep is depleted, your brain’s predictive emotional processing goes haywire — it starts catastrophizing and overreacting because it literally doesn’t have the resources to regulate properly. You’re not overreacting because you’re weak. You’re overreacting because your brain is running on empty.

Practical interventions right now:

Protect whatever sleep you’re getting ferociously. Same wake time every single day — even weekends, even after bad nights. This anchors your circadian rhythm when everything else feels chaotic. Grab a Manta Sleep mask and get Momentous Magnesium Threonate (with code foghorn) — it crosses the blood-brain barrier and meaningfully improves sleep quality.

Track your recovery with Whoop — join Team Foghorn Fitness free. When you can see your actual recovery data, you stop guessing and start making smarter decisions about when to push and when to protect.

Your move today: Set one non-negotiable sleep boundary tonight. What time does the puppy allow you to be in bed?

The resource tiles that surfaced below the response: Dr. Alia Crum’s Science of Mindset podcast, the Wim Hof Method book, Full Catastrophe Living, How Emotions Are Made, Hope for Cynics. Every one of them relevant. Every one of them something I personally put in the Vault.

Why I’m Showing You This

I’ve published three posts about this app. One about the features. One about why I designed it to not be addictive. One about the ethics of building AI for human performance.

This is the post I should have written first.

The app is not impressive just because of its feature set. It’s useful because at 8 a.m., when I’m running on fragmented sleep and have a full day of coaching ahead, it gives me fast, direct, specific access to the synthesized thinking of someone who has spent years studying this stuff.

That someone is me. Which means I’m getting my own best thinking back when I’m too depleted to access it myself.

That’s a strange and genuinely useful thing.

A few things I want to flag about that exchange, because they matter:

• It called me KJ. Not Coach Keir, not Keir, not “I understand you’re struggling.” It knew who it was talking to—because of a few questions in the onboarding process— and it was direct.

• It named the physiology immediately. No sympathy spiral. No “that sounds really hard.” Here’s what’s actually happening in your nervous system. Here’s why.

• The affiliate links surfaced organically. Manta Sleep mask, Momentous Magnesium, Whoop — these are products I actually use and recommend. They appeared because they were relevant, not because an algorithm was optimizing for commission.

• It ended both responses with a single, specific action. Not a list of ten things. Not an attempt at endless dialogue to artificially increase engagement. One move. Today.

• It asked a follow-up question. It didn’t assume. It narrowed toward what I actually needed. Then it sent me on my way.

That’s what “trained on my methods” actually means in practice. Not a chatbot that has read some random fitness content. A coaching interface that reflects a specific philosophy about how to help people, built from years of my writing, research, and direct work with athletes.

You don’t have to have a puppy. You can have a deadline, a training plateau, a sleep score trending the wrong direction, a knee that won’t cooperate, or just a week when everything feels like too much.

That’s what this app I built is for.

OK. Ellie is ramping up for another loud barking session in her puppy zone at the moment, looking for attention. I’m going to do the breathing protocol right now.

Best,

Keir

What Do You Want Written on Your Tombstone?

June 15, 2026Healthai coaching, human performance, life, life coaching, mental-health, personal training, personal-development, personal-growth, purposekjbeadling Leave a comment

I know. Dark opener for a fitness newsletter, right?

Bear with me.

This is the first in a series of deep dives on the ten pillars of the Slowfit Method®. My framework for being as healthy and happy as possible, developed over thousands of hours of coaching, reading, and frankly experimenting on myself and anyone who’d let me. If you’re new here, the full method is at foghornfitness.com — worth a look before or after you read this.

I’m not kicking off with a workout. Not with a supplement protocol. Not even with a breathwork technique, though that’s coming.

I’m starting with a question about your funeral.

Because everything else flows from the answer.

Pillar #1: Purpose

When I designed the Slowfit Method®, I had to decide where to start. Ten pillars, each important. But one has to come first.

The answer was obvious: If you don’t know why you’re here, nothing else is oriented correctly. You can optimize your sleep, nail your Zone 2 training, build a meditation practice. And still feel like you’re running on a treadmill going nowhere if the whole machine isn’t pointed toward something that matters to you.

So we start with purpose. Your mission. Your reason for being.

Your answer to: Why am I here? And most of us have no idea. That’s OK! Keep reading, let’s see if I can help get you there, or at least pointed in the right direction.

The Tombstone Exercise

World-renowned performance psychologist Dr. Jim Loehr has spent his career thinking about exactly this. His book Leading with Character: 10 Minutes a Day to a Brilliant Legacy puts it plainly: at the end of your life, people won’t be praising your money, your title, or your status.

They’ll remember your character. What you gave. How you made them feel.

Loehr’s companion piece, The Personal Credo Journal, walks you through the hard work of crystallizing your life’s purpose. Prompts like: What are the major themes in your life? What words describe you at your best? At your worst? Are you more of a giver or a taker?

I’ve been working through the journaling myself. I won’t pretend it’s comfortable. Nor that I’ve got this thing dialed. I basically find myself disappointed in myself about something I’ve done or not done every single day. But I’m developing a much clearer sense of what I’m actually meant to be doing here. And that clarity is making me more intentional about how I spend my time. The things I choose to do that serve my purpose. The things I choose not to do that don’t. Where I direct my focus and attention (and where I don’t).

I’m also mindful here of Tsutomu Ohshima, the founder of Shotokan Karate of America (the school to which I belong), who famously said: “We must look at ourselves with the strictest eyes.” That’s the work. Not brutal self-criticism. Clear-eyed self-knowledge. Being honest with yourself, no BS. You don’t need to be a karate-ka (though it helps!) to appreciate this one.

This is why Pillar #1 is Purpose. Not double-unders. Not red-faced Tabata on a spin bike. In fact, this heavy topic is something I’ll address with new Foghorn athletes fairly early in a new training relationship. Because everything else flows from there.

Arthur Brooks on Happiness and the Second Curve

A book I kept coming back to while developing this pillar: Arthur C. Brooks’ From Strength to Strength: Finding Success, Happiness, and Deep Purpose in the Second Half of Life. Brooks is a Harvard professor, social scientist, and The Atlantic’s happiness columnist.

The book resonated with me personally. It helped put into perspective my own career arc. Big firm litigator to sports entrepreneur running a major big wave surfing contest to human performance coach. On paper, this doesn’t look like a clean trajectory, does it?

Brooks’ framework made sense of it.

As we age, our “fluid intelligence” naturally diminishes. The dynamism, the raw idea generation, the ability to out-grind everyone in the room. That fades.

But our “crystallized intelligence” rises. The ability to draw on a lifetime of experience, synthesize knowledge, teach, and mentor. If you can let go of your attachment to the first curve and lean into the second, you’re on the road to a different kind of success. And a much deeper kind of happiness.

This is where I’ve landed. I’m here to share what I’ve learned (and continue to learn). This is my purpose, and in it I’ve found a sense of peace.

Brooks defines happiness not as a feeling but as a combination of elements: enjoyment, satisfaction, and purpose. That third ingredient is the one most people skip. We optimize for enjoyment. We track our accomplishments for satisfaction. But purpose is the ballast. Without it, the good days feel thin and the hard days feel bottomless.

His prescription is strikingly aligned with what I built the Slowfit Method® around. Detachment from empty rewards. Genuine service to others (like you!). Deep relationships. Some form of contemplative practice.

Not hustle more, achieve more. That’s an endless treadmill. Instead be thoughtful—mission-focused—along the way. And slow down, go deeper, figure out what actually matters. Focus your efforts on that.

What the Science Says

Just like everything else I write about here, this isn’t soft stuff. The research treats purpose the same way it treats sleep quality or exercise frequency. It’s a health variable.

A 2024 peer-reviewed study found that purpose in life is a more robust predictor of mortality than life satisfaction itself. People with the highest sense of purpose had a 46% reduced risk of mortality compared to those with the lowest. They were 24% less likely to become physically inactive. And 33% less likely to develop sleep problems.

Then in the fall of 2025, UC Davis published findings from a 15-year study of more than 13,000 adults. People with a stronger sense of purpose were 28% less likely to develop cognitive impairment, including mild cognitive impairment and dementia. The effect held across racial and ethnic groups and remained significant even after controlling for education, depression, and the APOE4 gene—a known genetic risk factor for Alzheimer’s.

As lead researcher Dr. Aliza Wingo put it: purpose helps the brain stay resilient with age. Her co-author, UC Davis neurologist Dr. Thomas Wingo, added something I’ve been saying for years in different words: purpose is something we can nurture. It’s never too early or too late to start thinking about what gives your life meaning.

And the biological punchline: people with higher purpose scores show reduced epigenetic aging. They are aging more slowly at the cellular level.

So yeah, purpose isn’t a soft goal. It’s a physiological variable.

So What Do You Actually Do?

Start with Loehr’s tombstone exercise. Not morbidly. Seriously.

Sit somewhere quiet and write out, in three to five sentences, what you’d want your obituary to say. Not your title. Not your achievements. Not your stock portfolio. The kind of person you were. The impact you had. What people will remember.

Then ask: is the life I’m actually living pointed toward that?

Not perfectly. Nobody’s life is perfectly aligned with their stated values. But roughly. Generally. Is the trajectory right?

If yes: keep going with more intention.

If no, or “I’m not sure”: that’s useful information. That’s where the work starts.

That work, figuring out why you’re here and structuring your life accordingly, is in my view one of the most important health interventions available to you. More important than your VO2 max. More important than your sleep score. More important than your supplement stack.

What to Read

Want to dig a bit deeper on your own? Start with Leading with Character and The Personal Credo Journal by Jim Loehr.

Then From Strength to Strength by Arthur Brooks. And his follow-up, Build the Life You Want (co-written with Oprah Winfrey, which sounds odd but is genuinely good).

For a more philosophical angle: Iddo Landau’s Finding Meaning in an Imperfect World. His central argument is that most of us are far too hard on ourselves when we conclude our lives lack meaning. Your life is almost certainly more meaningful than you think.

Next up in this series: Mindset—specifically, why the story you tell yourself about your own abilities, how you perceive stressors, how you view the world around you— is one of the single most important variables in your health and performance.

Stick around.

Best,

Keir

The Most Underrated Longevity Drug Costs Nothing and You Already Know How to Do It

A Foghorn Fitness / Slowfit Method® dispatch

Oops, I did it again. I went and disappeared for two more years from this here blog. Again. I promise not to do that again. My apologies. The original intent of The Lemonade Chronicles was as a sort of real-time journal of a reluctant stay-at-home dad as he approaches mid-life. Most of the “action” (if you can call it that) transpired more than 10 years ago. Everything leading up to my mid 40s, and something of an existential struggle.

Ten-plus years on, and things are waaaaaaay different.

My kids are in their 20s and miraculously, my wife and I seem to have done a reasonably good job with the boys, Max and Everett. I suppose that parenting never really ends, but the degree to which we exert control over their lives lessens every day. And I’m cool with that. Hilary is still the rock of our family, steadfast as always. We’ve had some losses, as is the case with life. Hilary’s parents. Aunts and uncles on both sides of the family. We lost our beloved Lab Wailea a couple years back. And time is taking its toll on people around us about whom we really care.

As for me? My own evolution, as a human being chasing the elusive bright side, has continued. Picked up pace, even, in the last 6 or 7 years. Ten years or so ago, I had a lot of questions. What is the meaning of life? How do I take care of myself and the people (and animals) that I love? Am I doing it right? These questions served as the impetus for creating another (and presumably my last) little company.

This is the human performance company called Foghorn Fitness.

As I think about it, this is the culmination of my life’s work. Everything I’ve learned to this point. And really, somehow I think I’ve managed to build a pretty robust vehicle to help guide folks (and myself) to a happier and healthier life. There’s even an app for it!

I’ve been writing a ton, just not on this platform. Everything is now over at Substack. That’s now the place to go for the good stuff, though I suspect I’ll continue spinning yarns here, as well. If you’ve followed me years ago, agitating about Alien Heads, dogs who eat money, and missing the school bus, I think you’ll find this latest chapter of mine of interest. I hope you will. When last we were acquainted, I had so many questions about life. Maybe you did too. Now I think I have the answers. Well, at least some of them. I hope you’ll join me and come along for the ride.

—

To that end, I’m going to jump right into it. Maybe a more apt image would be walk right into it. Because this post is about walking. Walking? Yep. Walking. Bear with me….

Because this is a thing you already know how to do — have known since you were about a year old — that is one of the most evidence-backed longevity interventions available to you, costs absolutely nothing, requires no equipment, no gym membership, no coach, and can be done anywhere on earth.

You are almost certainly not doing enough of it.

Walking. That’s it. That’s the whole revelation.

I know. Anticlimactic. But stay with me, because the research is genuinely surprising, and the running boom — I say this as someone who runs — has done a lot of damage to walking’s reputation that it doesn’t deserve.

WALKING IS THE SIXTH VITAL SIGN

Dr. Courtney Conley and Dr. Milica McDowell just published Walk: Rediscover the Most Natural Way to Boost Your Health and Longevity — One Step at a Time, and it is the book I’ve been waiting for on this topic. What James Nestor did for breathing, what Kelly and Juliet Starrett did for mobility, Conley and McDowell do for walking. Their central argument: walking is as important to your health and longevity as sleep and proper breathing. It is the sixth vital sign. And yet we’ve almost engineered it out of our lives.

The details are striking. Your walking speed can predict your overall health status and risk of early death. Your risk of falls and longevity can be measured by your foot health. And the number of daily optimal steps is not 10,000, it’s fewer. That last one will rearrange some people’s mental models. And hopefully rearrange people’s shoe closets. Enough with the foot coffins, folks.

BORN TO WALK—AND LIFT, SPRINT & PLAY

Mark Sisson’s Born to Walk makes the case most forcefully, and it’s worth spending a moment here because his full prescription maps almost exactly onto the Slowfit Method®.

Sisson’s argument isn’t just that running is overrated. It’s that we’ve misunderstood the entire architecture of human physical activity. He describes a movement pyramid built around four layers:

Low-level aerobic movement — walking — as the foundation. This is your Zone 2 base. Sustained, conversational-pace movement that builds mitochondrial density, improves insulin sensitivity, and develops your aerobic engine without the joint stress of running. Walking is Zone 2 for most people. The running boom convinced an entire generation that anything less than hard cardio didn’t count. That was wrong. Instead, most of us are running ourselves into the ground.

Strength training as the second layer. Not optional. Sisson is explicit: lifting heavy things is what signals the body to maintain muscle mass, protect bone density, and keep hormones functioning as you age. Same argument Attia, Luks, and Topol all make in the longevity books I covered last month. Muscle is the organ of longevity.

Sprinting and high-intensity work as the third layer, but sparingly. Short, hard efforts a couple of times a week. Not chronic cardio. Brief, intense, and followed by full recovery. This is what Foghorn’s HIIT sessions are built around.

Play as the fourth layer. Sisson is serious about this one. Unstructured physical activity, sports, martial arts, open water swimming, anything that involves moving your body in ways that aren’t predetermined by a machine or a program. In the Slowfit framework this is the spirit behind karate, pickle ball, whatever gets you moving in ways your body wasn’t expecting.

The Slowfit Method® has been built around exactly this hierarchy since day one: low-and-slow aerobic base, progressive strength work, occasional high-intensity effort, and enough variety to keep the body adapting and the mind engaged. Sisson just gave it a name.

—

THE LONGEVITY CONNECTION

Last month I wrote about three longevity books, Attia, Topol, Luks. All three converge on the same point. Eric Topol’s seven-year Wellderly Study, the people who reached their late 80s without major chronic disease, found no genetic smoking gun. What separated them was lifestyle: they were physically active. They walked. Howard Luks makes it plainly in Longevity…Simplified: walking counts. Not as a consolation prize for people who can’t run. As a legitimate, evidence-supported health intervention.

THE BODY IMAGE RESEARCH NOBODY IS TALKING ABOUT

And here is the piece that’ll encourage us to touch grass. Outside Online published new research by Dr. Viren Swami, a psychology researcher who has spent years studying nature exposure and body image. In the largest survey on this topic, researchers analyzed self-reported habits of more than 50,000 people aged 18 to 99 from 58 countries. Despite vast differences in age, location, and gender, connecting with nature was linked to positive body image.

But the experimental work is the part worth sitting with. A short 30-minute walk in nature promotes improvements in positive body image in the immediate term. And here is the detail that really landed: when participants took a walk in a built, urban environment, high-rise housing blocks, offices, shops, and parking lots, the walk actually caused a slight decline in body satisfaction. Walking in a natural environment increased it.

Same duration. Same physical effort. Different environment. Opposite psychological outcome.

Swami frames it this way: positive body image is when we begin to think of the body not in terms of what it looks like, but in terms of how it functions, how it helps us navigate from place to place, and all the wonderful things it does for us in everyday life. Nature creates the conditions for that shift. The urban environment, shop windows, advertisements, the constant social comparison of city life, works against it. Sounds kinda like the social media comparison-o-rama, no?

This maps directly onto Conley and McDowell’s framing of walking as biological necessity rather than exercise. When you’re moving through a natural environment, you are not performing for anyone. You are a body doing what bodies were built to do.

ADD WEIGHT. SERIOUS THINGS HAPPEN.

Michael Easter’s Walk with Weight: The Definitive Guide to Rucking takes this one step further. Rucking, walking with a weighted pack, is one of the oldest forms of human physical training, refined over centuries of military conditioning. It loads the posterior chain, builds functional strength, and elevates the metabolic demand enough to produce real fitness adaptation while remaining low-impact.

Start with 20-30 pounds and go 2-3 miles. Build from there. I program rucking regularly for clients whose bodies are telling them to back off the high-impact work. Nobody has ever come back disappointed. If you’re going to read one book to get started, Walk with Weight is it. And GORUCK is my go-to when it comes to rucksacks (discount code in that link).

THE SLOWFIT METHOD® TAKE

Walking is the Movement pillar at its most accessible. But as Sisson makes clear, and as we practice at Foghorn every week, walking is only the foundation. The full pyramid is what produces lasting fitness: walk as your base, lift to preserve muscle and bone, sprint occasionally to keep your cardiovascular ceiling high, and play to keep your body adaptable and your brain engaged.

That’s not a novel prescription. It’s what humans did for most of our evolutionary history. We just stopped doing it when gyms started selling us the idea that one type of hard cardio was enough.

A few things from Walk worth implementing immediately: your walking speed matters, so don’t shuffle. Your foot health matters, so ditch the cushioned stability shoes and let your feet actually feel the ground. And the 10,000 steps target is more marketing than medicine, quality of movement beats raw step count.

One more thing: if you want to go deeper on any of this, the walking research, Zone 2, rucking, the Slowfit Movement pillar, Coach Keir AI knows the full methodology. The Slowfit Method® app is now live on the App Store, free to download with a 10-message trial. Ask it anything. It won’t shuffle. Want to learn more? Wrote about the new app here and here. I’m proud of it; sure hope you’ll check it out.

Your action today: go for a walk that is at least 30 minutes, outside, somewhere that isn’t a parking lot. Leave the earbuds out for the first ten minutes. Notice what happens to how you feel about yourself.

That’s the whole protocol.

See you out there somewhere!

P.S. Speaking of walking, did a fair amount of that up the infamous Baker Beach Sand Ladder this past weekend during the 2026 Escape from Alcatraz Triathlon. Congrats, too, to Foghorn athlete (and eldest son) Max Beadling on his first triathlon (and on absolutely smoking his dad).

P.P.S. New website, new merch! Please have a look at the latest & greatest Foghorn website and if you’re interested in a new Foghorn hat (blue on black logo pictured above), let me know!

What Now?

Greetings, friends. It’s been a couple years since my last Lemonade Chronicles post, sorry about that. (Or maybe, you’re welcome.) But I thought today might be a good day to pick the pencil back up. I’ve been writing plenty over the past few years, including finishing a 106,000 word memoir manuscript that I am actively shopping to literary agents (who have yet to nibble the bait). But I’ve also been writing in more of an email campaign format, with something of a different purpose from what I have written starting 10 years ago with this particular blog. The existential angst, butt-of-my-own-jokes prose familiar to TLC readers? Well I’ve managed to evolve that after a good hard look at my lifestyle, digging into the science about health and wellness, starting a new company called Foghorn Fitness, and even developing an entirely new approach to this stuff that I’ve coined The Slowfit Method™. Over the past five years, I’ve morphed into a human performance coach who trains about 100 people a week across group exercise classes, private coaching, and corporate wellness programs. And I send out semi-regular email missives to another 500-ish folks on topics like meditation, improving one’s sleep, physical training, mindset, breathwork, recovery, nutrition, drinking (less or not at all), building resilience, etc. More importantly, as a result of all this work, I’m waaaaay happier and healthier than I’ve ever been, living with an equanimity that I didn’t know was possible.

So now that we’re all caught up (and I hope all is well on your end, by the way), why am I posting on TLC after ghosting the platform for years?

Because things are different now. I should say at the outset that this is not a political message. I’ll leave the Monday morning quarterbacking to folks who are much more astute on that topic than I. Rather, and consistent with this new chapter of my own life and profession, I want to talk about how you can choose to respond to this new reality that we have all woken up to yesterday morning. Regardless of your political leanings, things are different now. By definition, we will be making our way in an environment with the stress dial turned up to eleven.

So what now?

First, notice that I wrote the word “choose” above. On purpose. As the Stoic philosopher and Roman Emperor Marcus Aurelius said, we really can choose how to respond to stress. The Buddha, too, is credited with a similar sentiment, his regarding the pain of a second arrow that we effectively inflict on ourselves. In other words, we don’t have to scream and pull our hair out and go all googly-eyed, foaming at the mouth, emotionally hijacked by external circumstances. It doesn’t have to be that way. We have a choice. Your reaction–the next arrow–is up to you.

Second, we have a whole grab bag of useful tools to manage stress. Any kind of stress. The hundreds of athletes I’ve coached over the past five years are probably tired of hearing me say this. But it’s true. Yesterday I wrote about a bunch of them at our disposal sort of in-the-moment: Breathing, moving, eating (real food), connecting, and sleeping. For my part, I took my own advice. I doubled down on my regular healthy habits yesterday, and I genuinely felt less overwhelmed by the political events. I’ve started the day the same way today, and I feel…calm. I’m not naive; there will be much ongoing vigilance required and plenty of work to do. From all of us. But I am not consumed by it. I am ready for whatever comes. I am choosing my response.

Third, let me share a bit more about that response. Please know that this stuff is all science-backed, folks. Nothing woo-woo or otherwise outlandish here. And it’s more relevant now than ever. Because this new political reality is a textbook example of an “evolutionary mismatch” the likes of which is responsible in large part for what ails our species. Metabolic dysfunction, cognitive decline, mental health issues, obesity, lesser longevity, loneliness, and so on. Our brain is on high alert, being chased (over and over again) by a saber-toothed tiger as we peruse our favorite news sites, social media sites, TV news, etc. I can pretty much guarantee that you’re breathing rapidly through your mouth even now just thinking about it all. You are, right? Close your mouth and take a long exhale. 🙂 The “mismatch” is the unhealthy combo of a perceived stressor without the moving around part. Unlike our on-the-go ancestors, we run the risk of being stuck in a chronic state of arousal while sitting at our desks, curled up on our couches, iPhone stuck in our face, smashing Snickers bars, yada yada. Nothing good will come from that, if we let that happen and leave things there.

So I’m not going to let that happen. And neither should you. I’m going to lean into my meditation, breathwork, physical training (swimming, surfing, cycling, running, lifting, karate, etc.–the photo at the top was taken during a little morning walk today), journaling, mindset, mobility, clean nutrition, proper sleep hygiene, meaningful social connections, building resilience, improving focus and minimizing distraction, etc. Details on all of this stuff can be found here. If you want to deep-dive into the science underlying this Method of mine, go for it; I’ve got links to enough primary sources to keep you occupied for years.

And this is really important: Please do not be intimidated or scared off by all of this. You don’t need to try to be me. This is not about me. It’s my job to do all of this stuff. All you have to do is make a positive change in the right direction. One change. Baby steps. Walk. Take the stairs. Back away from TikTok for a bit. Drink more water. Cut back on the booze a bit. Learn some downregulation breathing. See the sunrise. Or the sunset. Hide the Snickers out of sight. Lift something heavy and put it back down, right where you found it, then do it again. Everything helps! But you do not need to do everything all at once. Just start somewhere. You have so many choices. Make one.

Lastly, let’s not forget the whole point of this thing. By “thing,” I don’t mean democracy or the United States or the world. Nope. I’m referring to life. Your life. As in, what is the purpose of your life? Nothing that happened yesterday should have had any negative impact on your purpose. In fact, it may have actually strengthened your purpose. It did mine. As I wrote over a year ago, my purpose is to learn and to teach. It can be easy to lose sight of one’s purpose, though, in the mundane day-to-day, or in the perceived crush of new stress.

This past week I received an unsolicited email from a gentlemen whom I’ve never even met. Here’s what he wrote (and yep, I have his permission to share this, but I’m still anonymizing it a bit)–

Keir,

Thank you. Thank you for what you do. What you do is important and it matters! Although we’ve never met face to face you’ve had a huge influence and impact on me! I began a similar “no IPA / no wine” journey in late November 2022. I was on a trip to Phoenix with E. and a couple other high school buds in March 2023. During that trip E. asked why I wasn’t having any beer or wine. I mentioned that it was driven by health concerns and I was making progress in my quest. He then said “A friend of mine is doing the same thing. I’ll forward you his newsletter”.

From the point I read your first newsletter you’ve been a part of my journey. Through giving up alcohol and starting to move my body a lot more I’ve lost over 40 lbs and my body has responded. My doctor is no longer pushing me to be on diabetes medicine or statins. My other blood tests that were very concerning have all returned to healthy levels. While all that is important the one thing giving up the IPA and wine has given me that was very unexpected is the feeling of accomplishment and it may sound simplistic and very basic but…happiness. Life is good again.

I look forward to each newsletter you send. Your message in October regarding your two years IPA free was fantastic…congrats! I look forward continuing my journey and exploring your Slow Fit Method further in late 2024 and 2025.

I’m including a couple pics. My family is the most important thing to me. With my newfound health we are hiking and getting outdoors more (S. and I having fun at the top of a small mtn in upstate NY). I’m even in the process of completing the Spartan trifecta with my two “boys” (J., M. and I after finishing the “beast” at Killington in VT).

This email may be a bit over the top but you’ve had an impact on me. What you do is important and it matters. Thank you!

Today is “day 700” of my IPA/wine free journey…thank you for the gift you’ve given me!

Sincerely,
Joe

If I needed a reminder of my purpose (and we all do), why I put my feet on the floor every morning, Joe graciously provided that. I’m grateful for his note, and humbled by it. Sometimes it feels like I’m shouting into the wind with all this Slowfit human performance stuff. But Joe heard me. Thanks Joe.

And Tuesday’s election has inspired me in a similar way, believe it or not. I feel the same sense of purpose that I felt during the Pandemic when I first started Foghorn Fitness. In my view, now more than ever, we need to figure out how to survive and thrive in this new super-charged, stressful environment. Remember your purpose. Move forward, one little step at a time. Oh, and put that second arrow down. Let’s do this.
