The red, blue and black teams all go "green" for the week, participating in recycling and learning how to implement new environmentally friendly habits in their lives. They also learn to exercise without the aid of electricity, taking their workouts to a whole new level. This week's challenge is all about recycling, and the winners get something really environmentally friendly Ford Escape hybrids!.

For the first time ever this season, the players start competing as individuals rather than teams. A tantalizing temptation has the contestants overcome by the power of donuts and one player finds a valuable prize, but was it worth risking their diet for? Then a 24-Hour Fitness triathlon challenge allows a contestant to go home for 24 hours and surprise their loved ones but as always theres a twist.

As a reward for their hard work so far, the players are surprised with a day of star treatment and makeovers on the set of NBC's popular daytime drama Days of our Lives. Behind closed doors, family and friends wait to surprise their beloved losers who they haven't seen in over three months. Alison Sweeney is the host, and trainers Bob Harper, Kim Lyons and Jillian Michaels star.
