The Biggest Loser

Los doce concursantes regresan al campus donde comenzaron todo el proceso para ver cuán lejos han llegado.

It's all about families in the new edition of The Biggest Loser, which features four husband-and-wife teams and four parent-adult child teams trying to lose weight through diet and exercise as they compete for a grand prize of $250,000. Trainers Bob Harper and Jillian Michaels fly around the country, surprising their teams with the news they've been chosen for the show. Then it's off to The Biggest Loser ranch in California, where the contestants get a wake-up call from the show's doctor about what ages their bodies really are vs. their chronological ages because of obesity. Then the eight teams compete in their first challenge -- and the lucky winner gets immunity from this week's elimination. Alison Sweeney hosts the hit weight loss series.

The contestants get to bid on the percentage of body weight they think theyll lose this week, and the highest bidding team can win $10,000 -- but only if they reach their weight loss goal. Then its off to a wild sprint and slide challenge, with the winning team earning a phone call home. Later, Chef Rocco DiSpirito drops by to teach the contestants how to shop for and make healthy, tasty and affordable meals before an elimination round sends another team packing. Alison Sweeney is the host, and trainers Bob Harper and Jillian Michaels also star.

This week, the contestants take a road trip to one of the most beautiful places in the world - the Grand Canyon! On the way there, they stop by a convenience store for a temptation challenge with host Alison Sweeney that will provide the winning team a much more luxurious trip for their scenic getaway. Once they arrive at the Grand Canyon, they have to figure out how to work out with no gym and no trainers. Later, the family teams compete for an amazing prize in a kayak challenge on the Colorado River before heading back to the ranch, where medical problems threaten to sideline one contestant. Then a surprise shake-up at the weigh in makes for the most difficult and emotional elimination so far. Trainer Bob Harper and Jillian Michaels also star.

In part one of this two-part episode, one team gets to go home and surprise their loved ones, while another team cashes in on a prize to spend 24 hours with their trainer for a day they’ll never forget! Then the contestants face their toughest challenge yet - a water tower competition that tests their endurance like never before. Later, one group of contestants incurs the wrath of their trainer when it seems they aren’t working out as hard as they need to, to stay on the ranch. Alison Sweeney is the host, and trainers Bob Harper and Jillian Michaels also star.

In part two of this two-part episode, one group of contestants tries to convince their trainer that they are committed to stepping up their workouts. Later, one of the contestants has a heart-to-heart talk with her trainer about relationship issues with their family member. And a surprising weigh-in forces one team to send a family member home when they fall below the yellow line. Alison Sweeney is the host, and trainers Bob Harper and Jillian Michaels also star.
