Microdot led the two housemates through a variety of weightlifting exercises from machines to dumbbells. First, Lee Kyung Kyu attempted to press 60 kgs (~132 lbs) on a machine, but gave up after a few tries. Sunggyu then stepped up to prove that he could do it and succeeded on the first try with his "serious face". However, a couple more presses, and the idol's arms began shaking heavily, leading him to jump off the machine in embarrassment!

Later on, Sunggyu endured some reps with some medium-weight dumbbells only to be bested by Microdot and his notably larger dumbbells. Microdot also commented that Sunggyu looks like rapper DinDin, but Sunggyu didn't seem to agree.
