(S09E06) In honor of the 2010 Olympic Winter Games, so conveniently on NBC as well, the contestants of 'The Biggest Loser' got to spend their week working out with the world-class athletes at the Olympic training center in Colorado. The vacation, along with the higher altitude, impacted how their bodies reacted to their workouts, leading to smaller numbers on the scale, and one startling result.

To make matters worse, Alison informed them they would not only be competing this week as individuals, instead of teams, but that two of them would be sent home. It was the return of the dreaded red line. The contestant falling below that would be eliminated immediately. The next two lowest percentages of weight loss would fall below the yellow line and one of them would be going home. But even that process wasn't quite as expected.
