Apple’s Fitness+ subscription service rolls out in the United States, United Kingdom, Australia, Canada, Ireland, and New Zealand today.

Apple announced Fitness+ back at its September 15 ‘Time Flies’ event, alongside the Apple Watch Series 6. The workout–focused service is designed to utilize the Apple smartwatch range’s array of fitness-tracking sensors.

Apple Fitness+ is an all-encompassing personalized workout experience that delivers studio-style workout videos to your ‌Apple TV‌, ‌iPad‌, or iPhone, all whilst feeding in the appropriate fitness metrics (calories burned, heart rate etc.) from your Apple Watch. A custom recommendation engine will serve up the most appropriate workouts for users, and you can use Apple Music to customize the soundtrack to your exercises.

Apple has assembled an extensive fitness team made up of expert trainers from across the disparate workout disciplines, including strength, HIIT, and yoga specialists.

All of the sophistication and specialization is on Apple’s end, however. Most of the workouts can actually be completed at home, with no equipment at all, and workouts can last anything between 5 and 45 minutes. There’s a beginner’s program for those who haven’t exercised in a while, too.

Of course, if you can access a gym, or have a treadmill, exercise bike, or rowing machine at home, then Apple Fitness+ has a number of activities that will cater to advanced users.

Fitness+ can be located within the Fitness app on iOS, and there’s also a new Fitness app for the ‌‌Apple TV. The service costs $10/month or $80/year, but Apple is offering three free months of the service with new Apple Watch purchases. It’s also included as part of the $30/month Apple One Premier bundle.
