Twelve finalists, nearly 3,000 lbs, one goal -- to go from an eating machine to a dancing machine in Oxygen's new dance/weight loss competition series Dance Your Ass Off, hosted by TONY Awar-winning actress Marissa Jaret Winokur.

Bringing dance and diet together, Dance Your Ass Off features talented, full-figured contestants who will have to lose to win. Each contestant is paired with a professional dance partner who will train him or her for weekly stage performances -- ranging from Hip Hop, to Ballroom and even Pole Dancing! Then they shake and rattle their rolls in front of a live studio audience and a panel of expert judges. The judges score the routines, and then the contestants weigh in to reveal their weekly weight loss. The dance score and the weight loss are combined for an overall score, which determines who is sent home each week.
