I can't even begin to sing the praises of Zumba. I started going to classes last month and I am addicted in a big way. It is SO MUCH FUN.
Today I bought the game for the Kinect but haven't tried it out yet. As for the dvd program, I imagine that any program like that will eventually get old, but I bet it would take awhile. The classes are worth it though if you can find them nearby. I have a Y membership and we have classes available every day but Sunday.
All different people go to them, we have everyone from pregnant girls to little old ladies and everything in between. I really like it because you set your own intensity according to your ability and can up it when you want to.
As for the calories...it burns more than just about ANYTHING else and the time flies. The average calorie burn for a typical class is supposed to be 600-800 per hour. There is a girl in one of the classes I take that wears a Body Bugg and last week she burned 1078 in one class. CRAZY.
Zumba isn't the only thing I'm doing, but I have lost just over 24 lbs since I began this journey on February 16th.
