The inner girl in us loves a good belly dance. So why get it in with the goal of flattening the abs. On Wednesdays, Sweat Fitness is offering cardio belly dancing. The class is taught by Alexa Krepps. The low-impact classes includes warm up, isolation and toning. And participants will get to put together their own dance routine. (Next stop is the poll, of course.) Classes are at Sweat Fitness in Center City located at 1425 Arch Street; It is free for members and $15 for non-members. Now you have no excuse for not putting on a bikini this summer and we mean it. Have any of you out there tried bellydancing? Is it a true workout?
