Tensions rise when contestants learn from host Alison Sweeney that two players will be eliminated this week ? so only six of the eight remaining players will still be in the game after the weigh-in. With the stakes so high, players are more determined than ever to stay above the yellow line. First, there's a tennis ball pop challenge that rewards the winner with an advantage at weigh-in. Then the contestants have to jump through hoops ? literally ? when they head to the circus for a lively challenge with the coveted prize of immunity for whoever wins. Later, contestants are led by trainer Bob Harper through a wild, trapeze-swinging last chance workout, only to return to the ranch and find trainer Jillian Michaels ready to put them through a second, grueling last chance workout. Then a dramatic weigh-in leads to heartbreaking eliminations as the contestants say goodbye to two more players.
