Lindsay Lohan is to continue with the "erotic yoga" pole dancing classes she took to prepare for her new film role as a stripper - because the sessions have made her a better dancer. The troubled actress plays a risque dancer in new movie I Know Who Killed Me and took up stripper classes to get into the part, and she's now hooked. She tells Movies.com, "I took these classes where you begin with sort of like erotic yoga to warm up. It was really hard on the pole because it takes a lot of upper body strength. "When I saw the scenes, I was surprised that I was dancing the way I was. I'm actually going to keep taking lessons because it makes me feel good."
