Check out episode photos of the first episode of season 11 of THE BIGGEST LOSER which premieres on Tuesday, January 4 on NBC (8-10 p.m. ET).
Episode Synopsis: In the premiere, the contestants will compete in a challenge and then get to make a game-changing decision in the order in which they finished. Host Alison Sweeney will offer the eleven family and friend teams of two the unprecedented opportunity to choose whether to work out with trainers Bob Harper and Jillian Michaels at the ranch – or work out at a secret location with two unknown trainers, whose identities will initially remain a mystery. If the contestants choose the new trainers, whom they know nothing about, they’ll receive four weeks of immunity. If they choose to stay at the ranch and be trained by Bob and Jillian, they’re at risk of going home after just one week. What ensues is a riveting ride of intense emotions, surprising turns and "can’t miss" moments as the two groups fight their weight loss battles separately with two sets of trainers equally committed to giving these players a new lease on a healthier life.
