About Prept

Most people who train already find good workouts. They save them — to TikTok favourites, an Instagram collection, a camera roll full of screenshots — and then never see them again. The workout exists, but it isn't usable: you can't follow a 30-second video set by set, you can't search it, and you can't tell what you trained last week.

Prept closes that gap. You share a video to the app, Prept reads it and writes out the actual workout, and from then on it behaves like a routine rather than a bookmark — something you can schedule, follow, log and look back on.

Prept is not a coaching service and does not write training programmes for you. It does not give medical, nutritional or rehabilitation advice, and nothing in the app or on this site is a substitute for a qualified professional.

It is also not the deepest gym logger available. If your priority is long-run strength analytics or barbell periodisation, dedicated loggers do that better — and we say so plainly in our comparisons. Prept's job is getting a workout out of a video and into your week.

Prept is free to use with an optional paid subscription, Prept Pro. There are no ads, and Prept does not sell user data.

Being clear about this matters: an app that is free, ad-free and doesn't sell data has to be paid for somehow, and in Prept's case it is paid for by the people who subscribe.

Alongside the app, this site publishes free, no-signup fitness calculators and a muscle anatomy reference. Every calculation runs in your browser — nothing you type is uploaded, stored or sent anywhere. The formulas used are named and sourced on each page so you can check them.

Support, press, bug reports, data requests and partnership enquiries all go to support@prept.pro. It reaches the person who builds the app.

What is Prept?

Prept is a free iOS and Android app that saves workout videos from TikTok, Instagram, YouTube and other platforms, and automatically turns them into structured workouts with exercises, sets, reps and the muscle groups they train.
