Three guides, in order. Everything else builds on them.
Sleep, light exposure, and movement are not specialist topics — they are what every person's health runs on. Most people have never had a clear, honest, evidence-based account of any of them. These three guides are where that changes.
Introduction
Why this guide exists — and how to use it
Sleep
The foundation of everything — no other intervention comes close
Light & Your Body Clock
The free tool that governs your energy, sleep and mood
All 19 archive guides are free to read. No account needed.
A preview, not the whole picture
Small errors, repeated by almost everyone.
Not the advanced stuff — the basics. Things that take no equipment, no gym membership, and no special knowledge. They just don't get done.
Sleeping in on weekends is quietly making your whole week worse.
Waking up at different times on weekdays and weekends is one of the most common things people do — and one of the most disruptive. Your body clock runs on consistency. Even one late morning shifts your internal rhythm and makes Monday morning genuinely harder to wake up for. Same wake time every day, including weekends, is the single biggest lever for sleep quality.
Most people spend their first hour awake looking at a screen instead of going outside.
Getting outside within 30–60 minutes of waking up — even on a cloudy day — sets your body clock for the whole day. It affects when you feel alert, when you feel tired, and how well you sleep that night. Screens don't do it. The light needs to come from the sky, and it takes less than 10 minutes.
Most people who "do cardio" are working out in the zone that gives the fewest benefits.
Moderate-intensity cardio — too hard to sustain a conversation, not hard enough to really push you — is the least productive place to exercise. The real benefits come from going genuinely easy (a pace where talking is comfortable) for most of your cardio time, and going genuinely hard in short bursts a couple of times a week. Most people do neither.
Most people lift weights without ever making them harder — and then wonder why nothing changes.
The body adapts to what you ask it to do. If you're lifting the same weights, doing the same reps, in the same order every week, you're maintaining at best. The only thing that produces change is gradually making the workout harder over time — more reps, more weight, or more sets. Almost nobody tracks this, which means almost nobody progresses.
Premium Guides
The science is free. The implementation is here.
Funds the research. Doesn't gate the science — every free guide stays free regardless.
Free guides answer what the evidence says and why. Premium guides answer what to actually do with it — the exact numbers, schedules, and decision rules you'd otherwise have to work out yourself by reading the same studies we did. Understanding is free. Implementation is what you're paying for.
The Science of Exercise
A complete framework for strength, endurance, and longevity — read on the site, plus a PDF copy. Updated regularly as the evidence evolves.
The Science of Nutrition
A complete framework for energy balance, protein, and food quality — read on the site, plus a PDF copy. Updated regularly as the evidence evolves.
The Science of Sleep
This is knowledge every person should have. It's free.
No account. No paywall. No agenda. Read any guide — or start from the beginning with the Introduction.
Guides are revised as the evidence changes — not a static download. What's accurate today gets corrected, not just published.
