The brand new application will track physical activity across the majority of Kinect titles with the help of Joule, a new heart-rate monitor.
With the aid of Joule, the fitness tracker will store information in the cloud, assisting users in their bid to lose weight, increase strength and improve overall levels of fitness.
Users can also benefit from Kinect Fit Play's stat-tracking service without the Joule heart-rate monitor, reports The Verge, although exact details remain thin on the ground.
Microsoft is yet to confirm the application, but will likely announce more during this year's E3 event in Los Angeles.
There are a number of fitness titles already available on Kinect, including UFC Personal Trainer and EA Sports Active 2.0.
Adidas, meanwhile, will release its own fitness title this summer, titled Adidas miCoach. The keep-fit game features guest coaches such as Kaka, Dwight Howard, Jose Mourinho and Ana Ivanovic.
It will be available exclusively for Kinect on Xbox 360 and Move on PlayStation 3.
