Exergaming or exer-gaming (a portmanteau of 'exercise' and 'gaming') is a term used for video games that are also a form of exercise. Exergaming relies on technology that tracks body movement or reaction. The genre has been credited with upending the stereotype of gaming as a sedentary activity, and promoting an active lifestyle. However, research indicates that exergames do not actually promote a more active lifestyle. Exergames are seen as evolving from technology changes aimed at making video games more fun.
