Using Kinect technology, Xbox Fitness can read your heart rate without a monitor, says Microsoft. It can also detect which muscles are most engaged, and track the quality of exercise.

Xbox Fitness can also deliver personalized program recommendations based on workout history and past performance, and highlight workouts popular among Xbox Fitness users, says Microsoft. 

The Xbox Fitness library includes Beachbody’s P90X (Tony Horton) and Insanity (Shaun T), Jillian Michaels, Tracy Anderson among others. It will be available for free with Xbox Live Gold memberships through December 2014.
