Stop guessing.
Show the work.
The Stat Method turns the messy parts of nutrition, training, body composition, and recovery into instruments you can inspect. Change an input, follow the model, and see exactly what moves.
Tools built like tools.
Small, focused calculators. Each one exposes the model behind the result and links you to the source material.
Useful reading, without the filler.
Training frequency and rest days
For muscle size, how you spread your sets across the week barely matters; for strength, practice pays. And how much rest you need depends on how hard you train.
ExerciseProgressive overload: how to keep making progress
Progress does not have to mean more weight. Adding reps works too — what matters is asking a little more of the muscle, and knowing when the load should follow.
ExerciseTraining volume: how many sets do you actually need?
More sets build more muscle, but each extra set buys less than the last — and strength stops paying out far sooner than size does.
No upsell, no gatekeeping, no hand-waving.
Every equation named
Each calculator lists the formulas it uses and the papers they came from. No black boxes.
Open source, auditable
The math is on GitHub with unit tests. Read it before you trust it.
Every source verified
All 80 citations were checked against the original papers — that they exist, and that they support the specific claim made.
