In this season of "no excuses," this week's challenge addresses the excuse "I can't lose weight on my own." Trainers Bob Harper and Dolvett Quince are suspended over water in a wild dunk tank-like challenge in which the red and black teams have to use their strength to keep a weight from landing their trainer in the pool. The losing team has to do without their trainer all week until the last chance workout. Once the losing team is determine, one contestant admirably steps up to lead their group while their trainer is away, with none of them aware that he is secretly watching how they do in his absence. Later, a very heated elimination sends another player home after a tense weigh-in to see how both teams did this week.
