'My Instructor tried to kill me....."

I confess. I'm completely, probably 98%, out of shape. This profound confession comes as a result of the Zumba class I attended last night. After an hour of dancing around - I'm completely exhausted and I can barely walk normal today. The class was a hoot though, and the instructor really knows how to get you moving. Zumba is amazing - I can feel every single muscle working. I dipped into my bank account and decided to pay out for 6 weeks of Zumba - one class on Monday evenings and another on Wednesday evenings. Mixed with some elliptical and eating well - if I don't see progress I don't know what else to do!
