Season 7 begins by introducing the players, who will compete in pairs. Grandparents, best friends and former plus-size models are among the twosomes. The group also boasts the oldest contestants and the heaviest contestant in the show's history.

The players encounter temptation, forcing them to assess why they've come to the ranch. Later, they compete in a race for immunity and a phone call home, and Bob clashes with a contestant during the last-chance workouts.

The contestants get a blast from the past this week with visits from season five winner Ali Vincent and season six winner Michelle Aguilar, both filling in as host while Alison Sweeney is on maternity leave. The contestants are also surprised by the arrival of some old friends, whose return promises to shake up the competition. And while one player is sidelined by medical issues, the rest compete in a balance and endurance challenge that finds each contestant standing on a platform, suspended six feet over a pool. One by one, the lines supporting the platform are removed, making it harder to stand, until only the winner is left standing. Later, Bob has last chance workouts at the beach before the weigh in, which is followed by a surprising elimination. Trainers Bob Harper and Jillian Michaels also star.

This week brings a pop challenge that will add an interesting twist to the weigh-in, and later, the contestants head to 24 Hour Fitness for a relay race competition. The winning team gets 24 hours of luxury, including spa treatments, but some contestants have trouble resisting temptation during their 24-hour getaway. Also, one contestant has a big blow-up with their trainer, and all of the contestants get some welcome and surprising news from host Alison Sweeney after elimination. Trainers Bob Harper and Jillian Michaels also star.

The competition heats up when the eight remaining contestants are faced with a temptation that will give the winner all the power this week. The players come to the gym and find 100 trays before them, under which there are high calorie snacks, cash prizes and the golden ticket - the one and only vote at this week'’s elimination. They can uncover as many trays as they like, providing they eat whatever they uncover. Then Chef Rocco DiSpirito returns to teach the contestants how to make healthy, lower-calorie versions of the dishes they used to order in restaurants, and later, two familiar faces from last season give the players encouragement and advice. This week’s challenge finds the players running up and down the steps of the Pasadena Rose Bowl competing for an incredible vacation prize. And after the weigh-in, the temptation winner casts the sole vote to send another player home. Alison Sweeney hosts, and trainers Bob Harper and Jillian Michaels also star.

It'’s Super Bowl week on the Biggest Loser ranch, and that means food, football and fun with two special guest stars celebrity chef Curtis Stone and NFL MVP Kurt Warner. First, Stone tests the contestants’ calorie knowledge of traditional Super Bowl snacks, then teaches them how to make healthier versions. Later, one contestant has to leave the ranch for a very important arrival at home, while another surprises her teammates with a new change in attitude. Then it'’s time for the challenge, when Warner puts the contestants through an NFL-style drill that will give the winner an especially valuable prize this week. Then the partners who were sent home for 30 days while their teammates stayed on the ranch are welcomed back. But the reunion celebration is quickly followed by a tense weigh-in and elimination that will leave one team heading home. Alison Sweeney hosts, and trainers Bob Harper and Jillian Michaels also star.
