CK's leg day: Lunges

Clark has a hard time figuring out how much weight he should do for each exercise because everything feels light to him. Too much weight, and people will think he's a freak. Too light a weight, and people will snicker...

He also can't figure out how 'strained' he should make his face, and how much grunting sounds produce. His best bet is just to copy the other men who do the same exercises...
