MARTHA STEWART

After losing more than 10 lbs. in prison, Stewart (left, in 2004; right, in November) has kept her shape with morning yoga and hikes in the woods near her Bedford, N.Y., home, says friend (and Being Martha author) Lloyd Allen. She also weight trains and does up to 250 crunches at a time. "Being healthy is at the top of her list," says Allen.
