[Update: Xbox officially announced Xbox Fitness. Check out the promo video, telling you to push your friends harder. HARDER!]
A page on the official Xbox website leaked revealing Xbox Fitness, an exercise app for the Kinect 2.0 that will feature routines like P90X and Insanity, along with the famous trainers such as Tracy Anderson, Tony Horton, Jillian Michaels, and Shaun T.
The exercise stuff was big on the Xbox 360, largely because that was the only thing that really worked with the original Kinect. I say "worked" loosely here. Kinect 2.0 does seem way more accurate this time around, so I can see Xbox Fitness being pretty successful. Well, that is until the subscription fees kick in for this.
