Trainer tip: put down the mocha latte, fatty!

Everyone is in the gym, and Bob and Jillian administer particularly brutal beatings to the contestants who were at home for a month. Shannon says that Bob and Jillian ride them, literally, and we cut to footage of Bob on Shannon's back. Horsey! Jillian tells Laura that she can throw up, scream, yell and swear, but there will be no crying. Tara is a bit worried that Laura, punk that she is, won't be giving 115%. Filipe, meanwhile, is impressed at how seriously Sione is kicking ass. He's outrunning, outlifting, and generally outshining even Filipe. Bob loves the Blue Team, and for good reason. They're ones to watch out for.

Meanwhile, Jillian asks Aubrey how often she was really in the gym while she was home. Aubrey claims to have been in the gym four to five hours a day, and Jillian rips back with a sharp, "There's no way, baby." Aubrey says that she didn't do good on food. What, was she eating lard soufflé for dinner every night? I mean, you would REALLY have to not "do good on food" to negate four hours in the gym. Jillian tells Aubrey that she needs to make herself a priority, and ask for help. Aubrey interviews that she feels like an idiot when she asks for help because she's normally so strong and independent. Methinks Aubrey is going to be Dr. Phillianized but quick. Meanwhile, the Silver Team members aren't screaming at each other anymore! Well, for the moment. Carla is working really hard, which probably means she's too out of breath to really let loose with the yelling. Joelle is still inconsistent with the motivation and the working out.

It's challenge time! There is a dam, which befuddles everyone. Sami goes on and on about the importance of partnership before saying that each team member is tied to his or her partner. Methinks Sami is being punny! Indeed. Each team of two will be tied to a rope, which is in turn wrapped around a big pipe. The teams have to unravel enough rope to make it to the finish line. The first team across the finish line wins either $5,000 in cash or a two-pound advantage at the weigh-in - it's their choice. Effing Joelle turns to Carla and is like, "That's $2,500 each." While her math skills may be impressive, her commitment to the competition is not. Mike reminds us that two pounds is huge in the context of the game, and has often been the difference between staying and going home.
