"THE BIGGEST LOSER"

"GET MOVING"

01/20/2013 (07:00PM - 09:00PM) (Sunday) : NFL STAR ANTONIO GATES GUEST STARS - This week, the contestants are encouraged to "Get Moving," and find themselves pushed to new limits when they are introduced to the new outdoor gyms that each trainer has custom designed. The stakes are high, with another red line looming for whoever loses the least amount of weight, and the dreaded "week 2 curse" that has instilled fear in all the contestants. Dr. H visits the ranch, giving the adult players an eye-opening wake-up call about just how unhealthy they really are, and one trainer has a heart-to-heart talk with their team to try and get them on track. Later, NFL star and San Diego Chargers tight end Antonio Gates cheers on the adult contestants and kids at a football-themed challenge testing the speed, agility and strength of the adults as they compete for a special prize for the child on their team. Plus, the trainers do a special fitness test with the kids and season 10 winner Patrick House makes a special appearance before the dreaded red line at an emotional weigh-in sends another player home.
