The contestants arrive in the gym for their morning workouts and are greeted by Alison, who has a surprise in store for them. This week, the trainers will roll giant dice to determine one team member whose weight will count in the weigh-in. This means that every single team member must work extra hard to make sure that, if they're chosen, they'll be able to deliver a win for their team.
Before the Blue Team's workout begins, Bob pulls Gina aside to talk to her about her confidence. Gina has a tendency to doubt herself, and Bob makes it his mission to instill some confidence in Gina. Throughout the week, he'll remind her that she can do anything she sets her mind to. Gina is more than willing to live up to Bob's hopes.
With the drama out of the way, the teams get into their workout routines. Each contestant is filled with a sense of personal accountability. They all know that, at the end of the week, they alone may decide the fate of their team members, and nobody wants to let their team down. Dolvett talks to Jackson, who still gets sick during rigorous workouts. Dolvett encourages Jackson to keep working hard. It's not a problem for Jackson, who is more inspired than ever before.
After the morning workout, the trainers do a video chat with the Biggest Loser kids. During their video chats, the trainers encourage their kids to start a program to help them live up to this week's theme, "lead by example." Biingo decides to start an after school activity program to encourage kids to stay active and have fun. Lindsay decides to organize a pep rally to spread awareness about bullying. Sunny decides to start a fitness club in her neighborhood.
The contestants are taken to an empty warehouse to meet Alison, who introduces them to the Calorie Crush challenge. Alison chooses one contestant from each team to participate in the challenge. The contestant must navigate across a balance beam, avoid swinging pendulums, retrieve five plates and match it to the calorie counts on five food dishes. It's a difficult challenge, and after a number of falls and fumbles, Danni comes out on top and receives a package of letters from her family at home.
Across the country, the kids are hard at work in their efforts to lead by example. Sunny's fitness club has drawn dozens of kids from her neighborhood who are excited about staying active. Biingo's after-school sports club is drawing a crowd as well. Lindsay organizes an anti-bullying rally at her school, and Dolvett sends pop sensation Cody Simpson to help Lindsay spread the message.
This week's Last-Chance Workouts are a perfect combination of fun and brutality. Bob keeps his Blue Team in the gym for an intense workout. Jillian takes Danni to a parkour training center to get some one-on-one tips for jumping off of buildings with ease, and Dolvett takes his Red Team for some boxing lessons with the one and only Leila Ali. The workouts are all intense and rewarding in their own ways.
At the end of the week, the contestants gather for the weigh-in. This week, each trainer rolls a die to determine which of their team members will decide this week's weigh-in results. After each trainer rolls, it is determined that Joe, Danni and Jeff will be representing their respective teams in this week's weigh-in.
The Red Team takes the scale first. While every team member weighs in, only Joe's weight will be considered in competition. Jackson dropped one pound this week, Francy shed seven pounds and Joe lost eight pounds.
Next, the White Team takes to the scale. Danni is the only remaining member of the white team, so she has to participate in this week's weigh-off competition. Fortunately, she dropped six pounds this week. Weigh-ins are determined by percentage of weight loss, which means that Danni's loss puts her in first place in the weigh-in. She's safe for another week.
Finally, the Blue Team hits the scale. Gina lost four pounds, Alex shed three pounds, Michael dropped eight pounds and David lost three pounds. Finally, it's Jeff's turn to weigh in. Jeff's is the only weight that will matter in this week's competition, so there's a lot riding on this moment. Jeff takes to the scale and drops six pounds. It's a good loss, but it's not enough to get the Blue Team out of third place. Tonight, a Blue Team member will be heading home.
The Blue Team members vote individually, and in the end they decide to send David home. Despite his enthusiasm and hard work, David is dealing with an injury that prevents him from participating in rigorous exercise activity. This means that his weight loss is slower than many of the other team members, and the Blue Team needs big numbers to stay in the competition. David says good-bye to his team members and leaves the ranch.
