Host Alison Sweeney surprises the contestants with the news that one player from each team will be going home with their trainer - and that player's weight will be the only one that counts at this week's weigh-in. It's also Valentine's Day at the Biggest Loser ranch, and that means letters from loved ones go to the team who digs their way under an obstacle course of logs first with a 200 lb. dummy along for the ride, representing the contestant who has gone home. The red and black teams do their best to burn calories while their trainers are away, and one contestant gets help from Biggest Loser nutritionist Rachel Beller in preparing a special meal for their loved one. Then the trainers and the two players they went home with return for a tense weigh-in before another contestant is sent home. Trainers Bob Harper and Dolvett Quince also star.
