Which muscles does your routine miss?
Tick the movements you already train. You get a body map of all 17 muscle groups, the ones falling short, and the two exercises that close the biggest gaps. No signup, nothing saved - it all runs in your browser.
What do you train?
Tick anything close - variations of the same movement train the same muscle groups.

How this works
Every exercise in our catalog carries a per-muscle activation percentage. Ticking a movement adds its numbers to the 17 totals; 100% is one session's target for a muscle, and anything under 90% is flagged. Same engine and the same numbers the app runs during a real session - nothing here is guessed by a model.
Do I need an account?
No. Nothing is sent anywhere and nothing is stored - the whole check runs in your browser, and the link in your address bar is the only copy of your answers.
It says I am missing muscles I definitely train.
Tick everything you actually do, accessories included. The check only knows what you tell it, and each tick counts as one exercise's worth of work - roughly three hard sets.
What counts as covered?
100% is one full session's work for that muscle. The app's default program hits 100-145% on all 17 groups every session; here anything under 90% is flagged as falling short.
What do I do about the gaps?
Add the two movements suggested, or let the app plan the session for you. Every new account starts with 14 days of Pro, no card.
