This is one of the best exercise I tried. I also have a friend who is fond of zumba. I admire her having all the time to go zumba. This is one of the reason why she maintains her petite body. Some months ago another friend bought a zumba xbox 360. We use to go zumba in their house. I remember sweating for almost an hour of zumba exercise. I love it because it seems that you are also dancing with the beat of disco music. The problem is, after doing zumba, we also eat a lot of yummy Filipino foods like humba. I am still hoping to go zumba again with friends. It is one of the best ways to work-out and exercise, thus losing weight. I need discipline to remove my excess weight since winter is coming..lol! I am thinking of buying zumba xbox 360 this holiday season.
