On a Samsung phone or watch, connect Samsung Health — that's the route we recommend, and your workouts become check-ins automatically. Health Connect also works, but treat it as a fallback: use it only if Samsung Health won't connect, or if you need other apps (Strava, Zepp, Mi Fitness) arriving through the same connection. Never leave both active at the same time — that's what causes duplicate check-ins.
Connecting Samsung Health (recommended)
Open GymRats and go to My Connections.
Select Samsung Health and tap Authorize permission.
Enable All permissions and tap Done.
Turn on the Active toggle.
That's it — your Samsung Health workouts will start becoming check-ins.
If Samsung Health won't connect: use Health Connect instead
Samsung Health also writes your workouts into Health Connect, and GymRats can read them from there. Use this route if Samsung Health won't connect on your phone, or if you already use Health Connect with other apps (Strava, Zepp, Mi Fitness) and want everything arriving through a single connection.
In Samsung Health: Settings → Health Connect → allow it to share your exercise data.
In GymRats, open My Connections and choose Health Connect.
When asked for permissions, choose Allow all.
Turn on the Active toggle.
Keep only one of them active
If Samsung Health and Health Connect are both active, the same workout can become two check-ins. Leave the Active toggle on for only one of them — on a Samsung device that should normally be Samsung Health.
If you're not sure which one is currently feeding your check-ins, see which source has your most recent workout:
In GymRats, tap + to start a new check-in.
Choose From device.
Compare Samsung Health and Health Connect — whichever is showing your most recent workout is the one that's up to date.
Go back to My Connections and leave Active on only that one.
Trouble syncing?
Check that the workout is in the Samsung Health app. If it isn't there, GymRats can't see it — the problem is between your watch and Samsung Health, so fix that side first.
Check that the connection still shows as Active in My Connections. It can drop after a system update.
Open GymRats after your workout. Sync only publishes your check-in once you open the app. See About Auto-Sync.
Let GymRats run in the background. Android may pause the app to save battery, which stops sync: Settings → Apps → GymRats → Battery → Unrestricted.
Update GymRats and Samsung Health to the latest version.
Check for pending firmware updates inside the Samsung Health app.
Try disconnecting and reconnecting, accepting all permissions.
