Summary: Still getting up to speed. Not for the couch potato. I'm 52 and have been behind a desk for the last 10 years. Had to get "Your Shape Fitness Evolved - Xbox 360" to work up to this. I was that couch potato!!! But it's good. And if you get to the point of mastering it. You're in great shape. From an ex collegiate athlete.
Summary: bought it to start working out...and needless to say it kicked my ass after not working out for over 6 months...it does get frustrating sometimes when you did something and it didnt register it..
