'80s Week

S6 E10: This week, contestants travel back in time to the 1980s, dressing the part and doing '80s style workouts and participating in a special '80s-themed challenge. Meanwhile, two players aren't speaking to each other, causing friction in the house and with one team in particular. Then an emotional elimination round sends another contestant home. Alison Sweeney is the host, and trainers Bob Harper and Jillian Michaels also star.
