Lose fat and build muscle at the same time.
For lifters who know the basics and want more from their training. Recomp gives every session a clear structure, suggests what weight to lift, and shows you when your body is changing, even when the scale doesn't move.

Bulking and cutting keeps you going in circles.
Most lifters spend months eating more to build muscle, then months eating less to lose the fat that came with it. A year later, they look much the same.
Trained lifters can lose fat and build muscle at the same time. The hard part is seeing it happen, because the scale barely moves.
Recomp measures what the scale misses.
A clear structure for every session.
Tell Recomp how many days you can train and which muscles you want to bring up. It lays out your week and keeps adjusting it as you get stronger.

Know what to lift, every set.
Recomp suggests a weight for every set and tells you when you're ready to go heavier.

Stuck on a lift? Recomp notices.
When an exercise stops moving forward, Recomp spots it and suggests a better option. Machine taken? Swap it for today, or for good.

See the change the scale can't.
Take a few tape measurements each week. Recomp tells you whether you're losing fat, building muscle, or both.

A report every 4 weeks.
See which lifts went up, how much you trained, how you slept and how your measurements changed. Then see what changes in the next 4 weeks.

The small things, handled.
Your daily calorie and protein guidelines. A rest timer that starts on its own. The plates to load on each side of the bar. Last session's notes, waiting on the exercise.

Built on research.
Recomp is based on published sports science, from how much protein you need to how hard each set should be.
