Why it works
What makes Prept's muscle tracker different
A body map for every workout
Each saved workout lights up the muscles it trains, from light work to hard-worked.
23 muscle groups
From chest and lats down to forearms, calves and adductors — Prept tracks the detail that generic trackers skip.
See gaps before they become imbalances
A weekly view shows which muscles you've been skipping so you can fix it before it's a problem.
Per-exercise detail
Even within one workout, see which exercise hit which muscle — not just the workout as a whole.
How it works
From saved video to logged session
Save a workout
From TikTok, Instagram, YouTube, or anywhere else — Prept reads the exercises.
Prept maps the muscles
Every exercise is matched to the muscles it works, automatically.
