openGym is a self-hosted gym and body-weight tracker that runs on your own server and keeps your data in a folder you control. It plans weekly routines over a library of over 5,600 exercises, guides workouts with rest timers and PR detection, and tracks progress with 1RM estimates, a muscle map and body-weight charts. It syncs between devices behind passkey sign-in, and it has no subscription, ads or telemetry.
