Apple Fitness+ is getting new workouts for beginners, older adults, and pregnant women, as well as a new trainer and an Earth Day-themed episode of Time to Walk with Jane Fonda.

Apple is putting in maximum effort for this year’s upcoming Black History Month, celebrating it across many of its services and introducing a special Apple Watch and Sport Band.

Apple has introduced a new Apple Fitness+ feature called Time to Walk, in which celebrities tell stories, share photos, and play songs to encourage you while you go for a walk.

In yet another feature-focused update to Apple’s entire stable of operating systems, the company introduced support for various new products and promised technologies, including Apple Fitness+, the AirPods Max, the Apple ProRAW image format, and more.

Apple has announced that its Apple Fitness+ service will launch on December 14th. Apple Watch owners can try it for a month for free, and those who buy a new Apple Watch get three free months. After that, it’s $9.99 per month or $79.99 per year.

Apple has expanded its stable of subscription services with the addition of Apple Fitness+, an integrated “workout experience” that relies on multiple Apple devices and an ever-changing collection of workout classes. Plus, the company will soon offer bundles of services under the Apple One name.
