The action button (green square with an arrow) hides some features.
You can rename and duplicate your workouts:
- Select a workout in the Workouts menu
- Tap the action button (top-right corner)
- Select rename or duplicate
In the same menu you'll find the following features, too:
- Send to watch: it sends that selected workout to your watch. Using this feature adds the workout to your database on watch, without deleting previously sent workouts.
- Workout sharing option via iOS email app and AirDrop
