The Apple Watch will be able to automatically detect if you have started a workout in the future. This function is useful, because a training will be recorded even if you forgot to start it explicitly.
For the automatic workout recognition to work, you need to make the following settings in the Apple Watch:
1. Open the settings.
2. Scroll down in the list and select the entry "General
3. Select "Training" in the next menu.
4. Activate the option "Reminder at start of workout".
5.If you want the workout to end automatically, please activate "Reminder at end of workout".
From now on, your workouts will be automatically recorded when the Apple Watch detects one.
