The Biggest Loser

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.

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.

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.
