This week, the contestants are surprised to find that the gym is empty - and the only equipment they'll be able to use is equipment they've successfully bid on with "Biggest Loser" bucks in the show's first ever auction, run by host Alison Sweeney. Trainers Bob, Jillian and Dolvett and the players have to get creative to make the most of their limited equipment. Later, one player opens up to her trainer about her difficult childhood, and all of the contestants re-charge their spirits with a very special treat - getting to skype with their loved ones back home in emotional, heartwarming family visits. Then it's time to head to the gym for a very emotional weigh-in. Also this week, the show catches up with season 12 fan favorite Vinny Hickerson.
