'Biggest Loser' trailer: Teams switch trainers - video
Watch the trailer below:
Last week's episode saw teenager Chism Cornelison sent home in a shock weigh-in after he missed his immunity weight-loss goal by just 1lb.
Every player had gone home for 18 days with the target of losing 5% of their body weight in order to gain immunity at weigh-in and ensure they wouldn't be eliminated. Unfortunately for Chism, he narrowly missed his target and as everybody else on the Black Team had immunity, he was sent home.
The Biggest Loser airs Tuesdays at 8/7c on NBC.
