Some women exercise to look good in their underwear, to put it frankly. That doesn't mean that they want to exercise in their underwear, though. And despite what you may think about classes called Cardio Striptease or Turning Tricks (a pole dancing class at Crunch), women aren't working out in lingerie or learning how to please their man. While these classes may be stripper-inspired -- or, in some cases, stripper-choreographed -- women leave their clothes on while performing routines designed to make them feel comfortable shaking what their mommas gave them. The name of the game is empowerment, not exploitation. These classes not only give women more self-confidence in the bedroom, they also give women a pretty good workout -- advanced moves on a pole require upper body strength like you wouldn't believe.
