The Biggest Loser - Season 9 Episode 3 -

During "student-teacher week," the contestants on each team assume the role of either teacher or student. "Teachers" get to continue working out with Bob and Jillian, but then have to teach what they've learned to their teammates or "students," who don't get to work out with the trainers. The "student'" on each team will be the only one whose weight counts at weigh-in. Acclaimed chef Curtis Stone teaches the contestants about portion control and helps them whip up a healthy chicken cacciatore dish.
