for physique and bodybuilding coaches
physique coaching, recomposition made visible
Track lean and fat as two masses on one honest scale, set versioned goals, and prove the recomposition the bathroom scale hides.
the scale hides the work
A physique client can train hard, eat to plan, and watch the bathroom scale sit still for a month. They read that as failure and lose faith, when underneath it lean tissue is climbing and fat is falling at almost the same weight. Bodyweight alone cannot show the one trade that matters to a physique, and a flat line on the wrong number is the fastest way to lose a client who is actually winning.
two masses on one honest scale
Trainbase tracks lean and fat as two separate masses, drawn together on one shared scale so the near-flat bodyweight reads flat and the widening gap between lean and fat reads true. Versioned goals sit beside the readings, so a target is a point in a history, not a number you overwrite and forget.
| the bathroom scale | trainbase | |
|---|---|---|
| what it tracks | one bodyweight number | lean and fat as two masses |
| recomposition | reads flat as no progress | the lean-up, fat-down trade, visible |
| body fat | not tracked | estimated from readings over time |
| goals | a target you overwrite | versioned, kept as a history |
| the client app | a number that demoralises | their own two masses, honestly drawn |
the scissor the scale buries
Twenty weeks of one client. Bodyweight barely moves, but lean and fat pull apart the whole way. On a shared scale the gap is the story.
what you build from
A deep library to program from, and the body model that proves the work.

the honest answers
Can a client really build muscle and lose fat at once?
Yes, and it is clearest in newer lifters, returning lifters, and clients carrying higher body fat. Trainbase does not promise the trade; it makes it visible when it happens, by tracking lean and fat as two separate masses instead of one bodyweight number.
How is body-fat percentage measured?
It is estimated from the readings a coach logs over time, not measured to the gram. Every estimate is treated as an estimate, and the trend across readings is read rather than any single number, so one noisy measurement never derails the picture.
Why track two masses instead of the scale?
Because a client in recomposition can hold the same bodyweight for weeks while lean climbs and fat falls underneath it. The bathroom scale shows a flat line and reads it as no progress. Two masses on one shared scale show the trade the scale hides.
prove the recomposition.
Track lean and fat as two masses, set versioned goals, and show every client the trade the scale hides, at a dollar a head.
