For the first time, the trainers, who for season 15's theme “Second Chances“ will be Bob, Jillian and Dolvett, are in charge of casting the fifteen people who will comprise the contestant list. After conducting interviews with the applicants, those fifteen chosen are brought to the Biggest Loser Ranch, where they learn that they will take part in their first workout before the trainers choose which five will be on Bob's blue team, which five will be on Jillian's white team, and which five will be on Dolvett's red team. During this workout, the naming of the team members and the first team workout, each contestant tells a little about him or herself and his/her motivation for being on the show.
