Abby Lentz: Yoga's Biggest Buff

This picture is not digitally altered. All 243 pounds of Abby Lentz are that flexible -- and the certified yoga instructor aims to help full figures everywhere get limber too. This year, she released her first DVD, HeavyWeight Yoga (available at heartfeltyoga.com). On it, she uses the formula of modified moves, slow pacing, and lots of encouragement that made her an outsize yoga star in Austin, where she teaches weekly. "Anyone in any shape can practice yoga," Lentz says. "You don't have to wait until you lose weight to get the benefits of a great workout."
