Microsoft Studios announced on Monday, June 27th in a blog post that the Xbox Fitness app on Xbox One would be shutting down in just over a year on July 1st, 2017. Effective immediately, the sale of in-game content has been stopped but previously purchased workouts will remain available through the end of the service.
On December 15th, 2016 the “Free with Gold” offer expires which took some digging to unravel. What that means is that the free workouts and streaming of previously purchased workouts come to an end. If you want to keep up with your workouts for as long as possible you’ll need to dig into the app and choose to download them before December 15th.
Finally, on July 1st, 2017 the app and all associated content will no longer be available to anyone. Similar to other online-only releases like Karaoke, the Xbox Fitness app may still launch but even if you have downloaded workouts on your console you’ll be unable to access them.
