Alerts and Videos can be managed under the Preferences section of your training.
Swipe left in the circuit overview until you enter the 'Preferences' screen.
Here, you can choose whether you would like to view your workouts as photos, or video clips.
You are also able to turn on, or off, your ‘Sirens’, ‘Notifications’ and ‘Tutorial’.
Keep in mind, enabling video workouts will use more data.
