This week, the contestants get an inviting offer from host Alison Sweeney to gain an advantage at weigh-in, but the offer comes with a steep price tag - losing trainers Bob Harper and Jillian Michaels for the week. Later, the players are faced with their first temptation, which will give the winner considerable control of the weigh-in. While Jillian gets very frustrated with a contestant who she thinks is far too focused on gameplay, another player finds she has an injury that will dramatically affect her workouts. Then an incline challenge tests the players' stamina before a very tense weigh-in, in which one contestant alienates the others with questionable choices, leading to a heartbreaking elimination.

This week, one contestant is sidelined due to a medical condition and frustrated about not being able to work out to their full capacity. And all of the contestants are in for a big surprise when they learn from host Alison Sweeney that the kitchen is off limits this week and why. A pop challenge about calories brings one winning team an amazing prize, and trainers Bob Harper and Jillian Michaels take the players out to a restaurant to help them learn how to make healthy choices when eating out. Later, a tough challenge tests all the players' endurance before a weigh in, after which another contestant is sent home.

Week five on the ranch kicks off with contestants getting the news that they're all going to be joining either trainer Jillian Michaels' black team or Bob Harper's blue team. But the bigger news from host Alison Sweeney is that whoever wins this week's temptation gets to make the critical decision of which contestant goes on which team. And when one person wins that much power, all of the contestants are worried about being potentially separated from the partner who has been with them since the beginning of their weight-loss journey. Later, a challenge tests the contestants' ability to work together in their newly-formed teams, and one player gives another a very special gift. Then a weigh-in leads to a tough elimination, sending another player home.
