"THE BIGGEST LOSER 9"
02/07/2010 (09:00PM - 11:00PM) (Sunday) : IT'S STUDENT-TEACHER WEEK AT "THE BIGGEST LOSER" RANCH -- Host Alison Sweeney surprises the contestants with the news that this will be student/teacher week, with the contestants on each team assuming the role of either teacher or student. The "teachers" get to continue working out with trainers Bob Harper and Jillian Michaels, but then have to teach what they've learned to their teammates or "students," who don't get to work out with the trainers. First, a temptation determines who will decide who the student and teacher are on each team, and later, contestants have to unravel their way through a challenge that grants immunity to the lucky winning team. Also, one player threatens to leave after the trainers try to determine what is causing her negative attitude, and an accusation about game play flies during a tense weigh-in, after which another contestant is sent home.
