The Biggest Loser: Couples 4 is the eleventh season of the NBC reality television series entitled The Biggest Loser. The contestants competed to win a $250,000 prize, which was awarded to Olivia Ward, the contestant with the highest percentage of weight loss. It premiered on January 4, 2011. Along with existing trainers Bob Harper and Jillian Michaels, two new trainers will be featured who were revealed in Week 3. One of the featured contestants is Rulon Gardner, a former gold medalist at the 2000 Summer Olympics. It was the longest season in Biggest Loser history at 20 weeks long. This season is the second, after Pay It Forward, to be filmed in high definition. This season marks the first time in USA Biggest Loser history that a contestant left the show by choice.
