We got this game on sunday and its crazy how it really does give you a workout. I didn't realize how much you can sweat playing a video game. For those who don't goto the gym often, you will be surprised how this game can make you use muscles you didn't know you had. It keeps track how many calories you burn doing certain games or exercises. The game is also suppose to help with your center of balance for better posture. If you know anyone who has this game, you should give it a try.
