This week kicks off with a wild challenge that will test the strength of both the blue and the black teams when each team has to pull a truck - and then put together a large puzzle with the crates they had to stop and load along the way. The winning team gets an amazing prize. Then it?s work week for the contestants, with each working eight-hour shifts at the food bank while also fitting in workouts in a specific time frame, a real-world task that proves very challenging for some. Later, the blue team squares off against the black team at a tense weigh-in before another player is sent home. Alison Sweeney is the host, and trainers Bob Harper and Jillian Michaels also star.
