Zumba is amazing! A friend of mine had been asking me to join her for Zumba for months and I finally caved three months ago. I've never in my life, stuck with an exercise program this long - and still love it! I usually attend 3-4 times a week. I haven't seen the weight "fly" off at all but the inches are definately changing! I'm quite the perfectionist so I really push myself during each class to really learn the steps. However, I was blessed with zero rythm so I am constantly tripping over my own feet. The instructor is fun and upbeat and she always encourages us to work at our own pace (either high impact or low impact). A good attitude and Zumba will be the best workout ever!
