This week, the tables are turned when contestants get to train their trainers and are only too happy to put Bob and Jillian through the paces! Later, the remaining five players have to race up and down hills while carrying bags representing their total weight loss so far in a particularly grueling challenge. Then it's time to visit Dr. Huizenga for a progress report and to find out their new "real ages" now that they've lost so much weight. The players also try on their "goal outfits" and are amazed to see how far they've really come. Then after weighing in and eliminating one more contestant, the final four players head home, where they'll stay for 30 days before returning to weigh in at the ranch one last time.
