This week's food temptation puts the trainers to the test instead of the contestants. If Bob, Kim or Jillian give into temptation, they could possibly be giving their team a 15-second advantage that will aid them in the upcoming physical challenge. As much as the trainers want the bonus time, they would not be setting a good example for their teams by choosing the easy way out. In the physical challenge, host Alison Sweeney explains the contestants must race up and down a hill to their team flag in the fastest time. But there's a catch -- the teams will have to try to outbid each other with a faster time, hoping that someone will wager lower and will be unable to succeed. This would result in knocking a team out. The reward for winning will be revealed at the weigh-in and sadly another person will be sent home.
