Work out together using SharePlay on Apple TV
Group Workouts, powered by SharePlay, let you and up to 32 of your favorite people work out together. You can start a FaceTime call on your iPhone, iPad, or iPod touch, then start a Group Workout in the Fitness app on Apple TV.
The workout plays in sync with everyone on the call, and everyone can control playback from their devices. You and your friends can cheer each other on, see when someone closes an Activity ring, and get notifications when someone moves ahead of the pack on the Burn Bar during HIIT, Treadmill, Cycling, and Rowing workouts.
Note: Group Workouts with Apple Fitness require Apple Watch Series 3 or later with watchOS 8.1 or later and one of the following Apple devices: iPhone 6s or later or iPod touch with iOS 15.1 or later, or iPad with iPadOS 15.1 or later. Playback on Apple TV requires tvOS 15.1 or later. FaceTime, some FaceTime features, and other Apple services may not be available in all countries or regions, and features may vary by area.
