Microsoft has launched a new Xbox 360 fitness application called PlayFit.
Out today in the US and in other regions later this week, PlayFit 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", according to Major Nelson.
Kinect PlayFit supports global leaderboards, Achievements, Gamerscore and Avatar Awards.
Earlier today, Microsoft detailed upcoming Xbox Live content for the next few weeks. Of note are tomorrow's release of Quantum Conundrum, the arrival of Mass Effect 3's previously rumoured Earth multiplayer DLC and Tony Hawk's Pro Skater HD next week, and sales on Oblivion and Fallout content.
