It's the halfway point in the competition and contestants get the exciting news that three NFL legends - Super Bowl champs Michael Irvin, Donald Driver and Willie McGinest - will be joining them this week. First, they'll be part of a football challenge in which a trainer and contestant from each team must catch footballs from the NFL legends - while tied together. And the stakes are high, because the winning team gets the coveted prize of video chats with loved ones. Later, the NFL players join the trainers in the gym and have fun putting their own spin on coaching the contestants. Then a red line at the weigh-in puts all the players on edge, while the Comeback Canyon weigh-in sends another contestant home for good.
