The Biggest Loser - Season 13 Episode 10 Week 10
5.50 90 minutes This week, the age-old excuse "I'm stuck in my comfort zone" is addressed as contestants are pushed out of their comfort zones by switching trainers for the week. The red team works out with trainer Bob Harper, while the black team burns calories with trainer Dolvett Quince. And one trainer gets out of his own comfort zone by trying ballet with his female contestants! Also, the teams get down and dirty in a 70-foot wide mud pit, filled with various weight plates they have to find in a messy challenge that will give one team a big advantage. Then it's time for the weigh-in, followed by an emotional elimination sending one more player home.
