Health Connect is Android's shared health data store. GymRats reads your workouts from it, and most Android apps and watches write to it. Samsung Health can reach GymRats this way too, if you prefer — it also connects directly. Use one or the other, not both.
Connecting Health Connect to GymRats
In GymRats, open the side menu → My Connections.
Choose Health Connect.
When the permission screen opens, select Allow all.
Turn on the Active toggle.
To change permissions later: open Health Connect (Settings → Apps → Health Connect on most phones) → App permissions → GymRats → Allow all.
Which apps reach GymRats this way
Samsung Health, Strava, Zepp (Amazfit) and Mi Fitness (Xiaomi) all write to Health Connect. Connect them to Health Connect in their own settings, then connect Health Connect to GymRats — you don't need a separate connection in GymRats for each one.
Using Samsung? Keep only one connection active
If both Samsung Health and Health Connect are active in My Connections, the same workout can become two check-ins. Start a new check-in → From device, see which of the two is showing your most recent workout, and leave Active on only that one. See Samsung Health.
If Health Connect stopped syncing with GymRats
Check that Health Connect shows as Active in My Connections, and that every permission is granted in the Health Connect app.
Open Health Connect and look for the workout itself. If it isn't there, GymRats can't see it — the problem is between your watch or fitness app and Health Connect, so fix that side first.
Android may pause GymRats to save battery, which stops sync: Settings → Apps → GymRats → Battery → Unrestricted.
Open GymRats after your workout. Your check-in is only published once you open the app. See About Auto-Sync.
