“Trainer save” added to Biggest Loser; cast includes 462-pound Ruben Studdard

American Idol 2 winner Ruben Studdard will be on the 15th season of The Biggest Loser this fall; the 462-pound singer will be “the show’s first celebrity player,” according to NBC, and he’s also the season’s biggest person. The 15-person cast also includes Olympic weightlifter Holley Mangold.

Also a first: the trainers helped cast the show, and will each be allowed to save one contestant during the season–kind of like Tim Gunn’s new power on Project Runway. That continues a trend of reality competitions giving people second chances, which perhaps not coincidentally is this season’s theme.

In a preview video, linked in the playlist below, Jillian says, “This game is fundamentally unfair, because it is a game.” She says the save is “the great equalizer” because the contestants “want to be worth saving” so they will work harder and rely less on alliances.
