The Biggest Loser: Battle of the Ages is the twelfth season of the NBC reality television series entitled The Biggest Loser. The contestants competed to win a $250,000 prize, which was awarded to John Rhode, the contestant with the highest percentage of weight lost. It premiered on September 20, 2011. Along with existing trainer Bob Harper, two new trainers joined this season. The 15 contestants this season were divided into three groups of five by their ages: those who are 30 and under were initially trained by Quince, those who are between 31–49 were initially trained by Harper, and those who are 50 and over were initially trained by Kournikova. This season marked the first time since season 5 that America did not have to vote on who would become a finalist. For the first time ever in Biggest Loser history, all 3 finalists were men.
