Season 11 of "The Biggest Loser" will see the departure of trainer Jillian Michaels and the introduction of two new trainers. And that's just part of this season's twist: Contestants will have the choice of working out with Michaels and co-trainer Bob Harper for one week and then face elimination at the weigh in. Or they can work out with two mystery trainers at a secret location for an entire month before facing the possibility of elimination. Once again this season's contestants are competing as partners. Among them: Olympic wrestler and gold medalist Rulon Gardner, a father and son from Pasadena and twin police detectives who are hard to tell apart. America, meet your contestants.
