I went into trying this game with an open mind. The punches worked but when doing lunges and squats it wouldn't register the movement. I play EA sports Active and them having the motion sensing straps is a much better idea. You would think that when coming up with a new game they would see what makes other games so successful and try to compete not come out with a half schemed idea and try to rip off the customer. This game would be good if it was just boxing. Don't waste your time or energy on this game. Maybe it's better on the kinect.
The game needs a leg strap to determine if you are doing all the exerises properly. If you don't have it the game is useless. It's better to buy the game new and it come with the leg straps then to rent it and have to buy the straps for a game you will be returning. The workouts that I could do without the straps were cool but all in all it was a waste of time.
