For some celebrities competing on ABC's Dancing With the Stars isn't just about winning the Mirror Ball Trophy. It's a lifestyle change. Most celebrities who snag an invite to compete for the grand prize get the chance to step outside their comfort zone and see themselves transform into a better dancer. And thanks to the rigorous rehearsal and training schedule, there are other stars who see an added benefit of weight loss along the way.
