Boys vs Girls week, the contestants competed as two teams, and chose a champion for each of the three disciplines – Strength, Speed and Endurance. The first team to win two rounds won the power of the Walk. In the first round, Strength, Ryan and Margie had to hold a 20 kg bar on their shoulders whilst their chosen question answerers, Hamish and Lydia, answered nutrition-related questions. For each incorrect answer, 5 kg was added to their bars. The first to drop lost the round. After 40 kg was on his bar, Ryan decided to give up, handing the first round to the girls.
