After facing body critics for over a year (she'll never live down those mom jeans), Jessica Simpson recently spoke to Oprah Winfrey about feeling more beautiful than ever, curves and all. "I'm comfortable with me. I love my curves. I'm not ever going to be a size 0 and weigh 90 lbs.," the size-4 singer said. The days of her fitting into her Daisy Duke short shorts may be behind her, but she's still hitting the gym with trainer Harley Pasternak about twice weekly for cardio and circuit training, including bench step-overs for limber legs. Take a cue from Simpson and readjust your definition of fit by finding an exercise regimen that works for you -- body and soul.
