What are your thoughts on Zumba? I don't mean in a gym or class with 30 other people...I mean the at-home, in the privacy of your own living room, personal DVD version? The 30 Day Shred kicked my but all over the house for a week and I only did it one time. I can't muster up the gumption to do it again. Plan B is to try something fun! I know nothing about Zumba, but I did watch some You Tube videos on it. Looks interesting! I'm thinking of buy a DVD and giving it a try - any suggestions??
