With summer rapidly approaching and a demand for that perfect beach body amplified, Xbox One has the perfect app to help chisel your physique. “Xbox Fitness” is a service exclusively found on the Xbox One console and features fitness and exercise videos from popular, top-tier trainers Tracy Anderson, Jillian Michaels, Tony Horton of “P90X” and Shaun T of “Insanity.” The game, developed by Microsoft Studios in partnership with Sumo Digital, uses the Kinect 2.0 sensor to track the player’s heart rate, estimate calories burned and give feedback about the player’s form, power and balance.
