You can use Siri to control your MySwimPro workouts on Apple Watch. First, make sure that you've enabled Siri permissions for MySwimPro. You can find them by going to the Settings app, select MySwimPro, then be sure "Use with Siri" is enabled.
After that, you will be able to control the workouts from your Apple Watch as long as it has an internet connection. Some things you can say:
- Hey Siri, start a MySwimPro workout in a 20 meter pool
- Hey Siri, pause the MySwimPro workout
- Hey Siri, resume the MySwimPro workout
- Hey Siri, end the MySwimPro workout
