Use JustGains with Garmin
Connect Garmin Connect™ to bring your runs, rides, sleep and recovery into JustGains, and send workouts, Forge runs and routes to your watch.
Your Garmin watch already knows how you slept, how hard yesterday’s run was and how much you have left in the tank. Connect Garmin Connect™ and JustGains puts all of it beside the lifting you log here, then sends your next session back to your wrist.
Connect your Garmin account
- On justgains.com, open Connected apps. It’s also in Settings on your profile.
- Choose Connect beside Garmin Connect™ and sign in with your Garmin account.
- Garmin shows you exactly what JustGains is asking for. Leave on whatever you want to share, then agree.
- You come back to Connected apps with Garmin Connect™ marked as connected, and the date it started.
What comes in
| From Garmin | Where it shows up |
|---|---|
| Runs, rides, walks, hikes and swims, with maps, splits and heart rate | Your feed, your profile and each activity’s own page |
| Sleep, HRV, resting heart rate, Body Battery™ and stress | The Recovery card on your dashboard, against your 7- and 30-day averages |
| Cycle tracking | Only if you choose to share women’s health in Garmin Connect™ |
Everything from Garmin carries its source right under its title: "Garmin Forerunner 965", or simply "Garmin" when the watch didn’t say. The label travels with it, onto a shared link, the picture people see when you post that link, a route leaderboard and any segment time it sets.
Log the same session in JustGains as well and the two are matched, so nothing counts twice.
Send workouts, runs and routes to your watch
- Workouts. Open any workout and choose Send to Garmin. Strength sessions go over set by set, and the result lists each exercise with the name your watch will show.
- Program weeks. In a program’s schedule, Send week to Garmin sends every training day of that week in one go.
- Forge runs. In your saved Forge for Runs plan, send one session from its details, or the rest of the week from the schedule. Each run lands on its day in your Garmin calendar with its paces and intervals.
- Routes. On a route’s page, Send to watch turns it into a course you can follow on your wrist.
Your watch picks up what you send the next time it syncs with Garmin Connect™. Change a workout and send it again, and the copy on Garmin is updated instead of doubled. Changed your mind? Open it, choose On your Garmin, then Remove from Garmin.
The first time you send
Before anything leaves JustGains, you see Garmin’s notice: what you send is copied to your Garmin Connect™ account, Garmin’s privacy notice applies there, and Garmin may keep it even if you remove it here later. Nothing goes until you choose Agree and send, and you’re only asked once.
When an exercise has no Garmin match
Garmin keeps its own list of strength exercises. Most of ours line up with one of theirs, and the send result tells you which name each one got. When there’s no match, the step still goes over and its note carries the JustGains name, so you know exactly what to do when it comes up.
Garmin data and AI
AI features like coach chat only read your Garmin activities and health data if you turn on Use Garmin data in AI features in Connected apps. It stays off until you switch it on, and switching it off counts from the very next answer. When an answer did lean on your Garmin data, it says so underneath: "Insights derived in part from Garmin device-sourced data." We never use Garmin data to train AI models.
Disconnect or delete
- Disconnect stops new data from coming in. What already arrived stays in your log.
- Delete everything we’ve received from Garmin disconnects Garmin and permanently removes every Garmin activity, with the route times, segment efforts and goal progress it set, plus all Garmin sleep and health data. Workouts you logged yourself stay put.
You can also remove JustGains from Connected Apps in the Garmin Connect™ app. Either way, Garmin data stops arriving from that moment. To fix a Garmin activity, edit it in Garmin Connect™ and the change comes through here.
