Shannan arrived to train his troops, delighted by the news that Lydia had secured herself a Weigh-In Pass. The others were led in a pool training session by The Commando, who raced the contestants in a special circuit, unsurprisingly coming out the winner. The final two Weigh-In Passes were up for grabs in a Biggest Loser Iron Man Challenge at Palm Beach. Brenda took the win with a determined effort, leaving Bek and Shane battling it out for the final Pass.
