The Biggest Loser has tried a number of different twists, but this season the weight-loss competition is doing a battle of the ages. Season 12, which kicks off Tuesday, September 20 at 8pm on NBC, will feature 15 contestants divided into three groups based on their ages.

There will be one group with people under 30, one over 50, and a third in the middle. In addition, the Biggest Loser premiere’s first challenge will decide the order that the teams get to pick their trainers. In addition to returning favorite Bob Harper, season 12 will feature new trainers Anna Kournikova and Dolvett Quince. I wonder if the young ‘uns will go with Kournikova based solely on hotness.

The 15 contestants for The Biggest Loser season 12 include a former NFL player and a Nashville singer. Here are the people competing to lose weight this season.
