The teams hit the road for the ultimate temptation town: Las Vegas, where the trainers teach skills for a hotel stay ranging from eating right when confronted with a buffet, to finding ways to workout within their hotel rooms. A card game that offers the chance to win up to $5,000 comes with high stakes - losing their trainer for the rest of the week. The team challenge for the opportunity to choose who sits out at the next weigh-in and to win a return trip to Vegas with their families consists of a relay race in the hotel swimming pool.
