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.

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.

This week kicks off with a temptation that host Alison Sweeney tells the contestants will allow one player to reunite with their teammate at home and bring their trainer with them. But the reunion doesn’t go exactly as planned when fireworks erupt between the two teammates after one player accuses the other of not doing all she can to stay on the ranch. Meanwhile the contestants check in with Dr. Huizenga to see how far they’ve come and how many medications they no longer need from the first three weeks of weight loss. Then a wild jump rope-like challenge results in immunity at this week’s weigh in for the winner, followed by a surprising elimination that sends another contestant packing. Trainers Bob Harper and Jillian Michaels also star.

Now that the contestants’ partners are back at the ranch, those who’ve been working out at home will weigh in and see how they have fared away from the ranch. Then all the players compete in this week’s “rope challenge,” and later, an elimination leads to tension on one team when one player thinks her partner hasn’t been pulling her weight. Alison Sweeney hosts, and Bob Harper and Jillian Michaels also star.

In part one of this week’s two-part challenge, contestants divide the amount of weight they'’ve lost so far among their opponents, with many ganging up on the player they feel is the strongest competitor. For part two of the challenge, the players head to the racetrack where they'’ll meet NASCAR driver Clint Bowyer. Then each contestant will pull a two-ton car plus the weight added on from part one of the challenge -- for almost a quarter of a mile! Also, the competition goes to singles this week and contestants are given their original colored shirts to wear for the rest of the competition. And later, one contestant breaks “Biggest Loser” records at a weigh in that finds several players hitting big milestones. Alison Sweeney is the host, and trainers Bob Harper and Jillian Michaels also star.
