Week 6

It's a star-studded Olympic-themed episode of "The Biggest Loser: Couples" to help kick off the winter games! This week, the contestants head to Colorado to train like Olympic athletes at the U.S. Olympic training facility in Colorado Springs. Host Alison Sweeney tells them the game is going from teams to singles, and multiple medal-winning paralympic athlete Allison Jones warmly welcomes them to the U.S.O.C. campus. Trainers Bob Harper and Jillian Michaels invite two Olympians to help work out the contestants - gold medalist skier Julia Mancuso and Jeret "Speedy" Peterson, the freestyle skier famous for his "hurricane" jump. Then it's off to a pop challenge involving a slide board, where U.S. Olympic speed skater J.R. Celski cheers them on. Later, they engage in a biathlon challenge before moving on to this week's last chance workout -- with pairs figure skater Rockne Brubaker! Then their exciting week comes to an end as two more players are sent packing.
