It's "Finals week," and each contestant will be tested by the trainers to see how much they've really learned at "The Biggest Loser" ranch, with the winner claiming a big cash prize. The players get a chance to add to their overall test scores by competing against each other in four difference exercises while playing "The Biggest Loser Ultimate Workout" on Kinect for Xbox 360. Later, the contestants are put to another test with a stair-building challenge involving weighted sandbags. The winner gets a weigh-in advantage that could help determine who makes it to the final four - and who is sent home.
