Yes there is one in the Zumba section on this forum
I LOVE Wii Zumba, although I do feel stupid doing it if other people are in the room, it really does help to lose weight and makes me feel like I have actually done a workout. Zumba along with Wii Fit Hula Hoop is really getting my huge hips down
ive done it first time yesterday to have a day of something different and i enjoyed it. dont know how it is calorie burning wise but i take it any exercise is better than sitting down.
