So you CAN do zumba class without joining the Y, but it's $15 per class.
Good news: I won a Zumba video system in a silent auction at work today!! We're raising money for the family we adopted for the holidays.
I did the "learn the moves" dvd, and did get my heart rate up and got sweaty for 50 minutes. Also reminded myself that I have NO coordination. Oh well, it was fun!
