A great game if you use it like you are supposed to. Very easy to cheat and not get a good workout though.
This game offers many different types of exercises. Yoga, strength, aerobic, and balance games are the 4 different categories to choose from. If you want to increase you balance and flexibility, yoga exercises are the way to go. If you want a real workout, the strength exercises will give you that. The aerobic exercises are just that, they will get your heart rate up and make you sweat (especially the boxing). And balance games are fun and work to increase your balance.
The one complaint I have with this game is that it gets kind of tedious shifting between accounts if you are playing with more than one person.
