Over the Top (1987)
Over the Top features Sylvester Stallone  (the fitness star of this decade) and focuses on championship arm wrestling. You might wonder: how the hell could a movie about arm wrestling make for a decent training montage? And you’re absolutely right. In this brief clip, Sly’s character named Lincoln Hawk (what else?) shows his estranged son the ropes, grappling mano-a-mano and strengthening their rassling arms in what looks like a very ineffective curling exercise on a semi-truck—ridiculous, but great nonetheless. It also includes a makeshift tricep pull-down Lincoln constructed in the cab of his big rig.
