I LOVE this game! It's a full body workout with 76 different sessions to choose from in various difficulties and lengths. It also builds your memory and reaction time! You have to follow the order of the hits after it shows them to you, and if you don't get them quick enough they'll disappear. As you workout you collect sweat drops which you can then use to unlock new skins for your gloves. There are 100 different gloves to unlock!
The music is great, the patterns are fun, there are so many different workouts you'll never get bored with the same one... AWESOME!
