Microsoft launched the Kinect PlayFit on Xbox LIVE as a free download for all Xbox Live members in the US. Kinect PlayFit is a new fitness dashboard that aggregates and tracks the calories you burn as you play a variety of Kinect games, from "Dance Central 2" to "Your Shape Fitness Evolved 2012" to "Kinect Star Wars."
Kinect PlayFit lets you view your personal stats over time and see leaderboards that show how you rank against Xbox LIVE members across the globe. Get credit for the calories you burn while having fun with Kinect, and earn Kinect PlayFit Achievements, Gamerscore and Avatar Awards.
Kinect PlayFit will launch in other regions later this week.
