It’s the halfway point in the season, and the contestants find out that the weight of only one player on each team will count this week, but they won’t know who it will be until the weigh-in. With this week’s theme of “Leading by example,” trainers Bob, Jillian and Dolvett skype with kid participants Biingo, Sunny and Lindsay, and motivate each one to do just that. While Sunny creates a circuit training routine for her fellow classmates, Biingo tries to recruit more friends to his after-school sports club. Lindsay gives an anti-bullying speech to her peers, joined by special guest Cody Simpson, who also talks about his experience being teased before performing for the kids. The adult contestants compete in a crazy challenge requiring them to avoid three swinging pendulums while walking on a balance beam to retrieve calorie-coded plates matching five specific dishes. Later, during last chance workouts, Dolvett’s team has a special visit with five-time undefeated world champion fighter Laila Ali, who put them through a fun and challenging boxing workout.
