The Biggest Loser

Down to Singles (15x10)

Air date: Dec 17, 2013

The contestants meet Alison for this week's Ring of Fire Challenge. Before the challenge begins, Alison informs the contestants that the competition is moving to singles. Once they've received their individual jerseys, the competition begins. The contestants must hold a 20-foot metal rod in a ring of fire as long as they can. The bar weighs 20% of the contestant's weight, and they're competing for a one-pound advantage. It's a respectable prize, and all of the contestants are eager for a big win.
