Apple Fitness Plus will launch on December 14, taking on at-home fitness competitors like Peloton

• Apple Fitness Plus, the new "fitness experience" by Apple, will launch on December 14.
• The workouts — which include strength training, yoga, cycling, and more — will be available on iPhone, iPad, and Apple TV.
• Apple Fitness Plus is powered by the Apple Watch, where users can monitor metrics like heart rate and total calories burned.
• Apple's foray into fitness adds to the growing at-home workout market, which has increased in popularity since the beginning of the pandemic in March.

Apple Fitness Plus launched on Tuesday for Apple subscribers. The company earlier announced the new "fitness experience" subscription program at its September event.

The program "brings studio-style workouts to iPhone, iPad, and Apple TV," according to a statement from the company. It's powered the Apple Watch, so users will be able to see real-time metrics, like heart rate and total calories burned, on the screen "during key moments in the workout."

Apple Fitness Plus does require a subscription, for either $9.99/month or $79.99/year. For those who already own an Apple Watch, a free month is included. The company is also offering three months free to anyone who buys an Apple Watch Series 3 or late. Workouts are available in 10, 20, 30, 45-minute intervals.

The platform will have 10 different styles of workouts to choose from, including "High Intensity Interval Training (HIIT), Strength, Yoga, Dance, Core, Cycling, Treadmill (for running and walking), Rowing, and Mindful Cooldown."

For now, Apple Fitness Plus will only be available in Australia, Canada, Ireland, New Zealand, the UK, and the US.

Apple's new fitness platform will add to the growing at-home workout space, which already has Peloton, and the Lululemon-backed Mirror. These products have soared in popularity as stay-at-home orders have kept gyms closed for a majority of the year. Peloton stock dipped slightly on the news of Apple's announcement. On Tuesday, Apple also announced its AirPods Max, a $549 pair of over-ear headphones, rounding out a busier-than-usual year for the tech giant.

In the past, Apple has hosted one large - often star-studded - event in September where new products and technology are announced. This year, the company held three smaller events in September, October, and November.
