The Knockout

Week two begins with the trainers and contestants getting to know each other and reveal more about themselves, with the exception of one player who refuses to talk about what led to her weight gain. This week's challenge has contestants busting through "walls of excuses" and racing through an obstacle course while carrying a punching bag, with the winning team getting a prize that none of the players want to be without. Then Dr. Huizenga meets one-on-one with contestants to reveal the results of their medical exams and what the future holds if they don't lose weight, leading one contestant to storm out of the room when the truth is too hard to hear. Later, the weigh-in at the ranch reveals which contestant will be headed to trainer Bob's Harper's "Comeback Canyon," while the weigh-in at "Comeback Canyon" ends with one contestant leaving the competition for good.
