01 — The framework

Four things to understand. Then you can run your own body.

You don't need a coach. You need to understand what you eat, how you move, how you rest, and how habits stick — well enough to run your own body for the rest of your life.

Fuel Calories, macros, protein, fibre, hydration — what to eat and why, with the math shown. Train Strength, cardio, volume, progressive overload — the kinds of work your body actually needs. Recover Sleep, rest days, stress and cortisol — the multiplier, not the afterthought. Rewire Habits, motivation vs discipline vs systems, identity-based change that holds.

02 — The toolkit & the warm corner

Tools a coach would charge for. Food you'd actually eat.

Tools Free tools. No login. No catch.

A calorie calculator, a macro calculator, and Bevel for tracking the trend. They show the math, not just the answer.
