I recently purchased the Wii game, Just Dance II and I have to say that it is the best workout ever! I love dancing, so it is a blast. I did a few songs this morning and walked away sweating. You are having so much fun you forget you are burning calories. It is so much fun! They also have a lot of different songs; from Ke$ha to Jackson 5. High Recommended!!!!
Here's the video trailer that shows some songs and dances!
