Actress Teri Hatcher has taken up a sexy method of keeping her curves firm - exercise classes based on stripping. The former Lois & Clark star is currently a devoted student at the Sheila Kelley's S Factor in Los Angeles, and she's thrilled with the results it has had on her body. Hatcher, who insists all students stay fully clothed during lessons, says, "It's all geared around stripping moves and we actually dance on a pole and we learn how to lapdance. I know it sounds funny, but it's great for all your muscles and it's actually really empowering because it's not about turning a guy on - it's about turning yourself on and learning to be comfortable with your own body." On Friday, Hatcher displayed her skills to excited comedian Jay Leno on his chat show
