Absolutely you will lose when you do Zumba I have the DVDs so I can do it at home, started with the Rapido and Advanced set...begining of last week I got a set of 3 and the hand sticks off Amazon site and I have noticed even a bigger difference in just a week, moves are a little harder but I don't care when no one is watching

It is the perfect workout I think...where was this 10 years ago?
