The contestants compete in two challenges this week to gain pound advantages at the weigh-in. The first challenge tests their nutrition knowledge, with their trainers consuming food for each incorrect answer. The "Wall of Glory" is revealed in the gym, showing contestants when they were top athletes, inspiring them to work ever harder in the gym. Then trainers Dolvett Quince, Jessie Pavelka and Jennifer Widerstrom help out at an endurance challenge before a weigh-in determines who will be headed to the surprise "Comeback Canyon" location with trainer Bob Harper and which of Bob's two eliminated contestants will be headed home.
