In a rare glimpse 3 hours in to this muscle razing hell-convention, we find Kai admitting that he's nearing his limit. Nick's close to collapsing, yet the song plays on. The pair machine gun out several additional sets of hamstring curls and leg extensions, their mind-muscle circuits savaged and surely teetering on a meltdown. Having visibly transitioned through several stages of emotion, Nick suddenly discovers the humorous angle of things realizing what he's just subjected himself to, a plausible reaction in retrospect. With his receptivity at a heightened state, he takes the opportunity to absorb more of Kai's final thoughts on what it will take for him to reach the next level as an athlete. With no gas left in the tank, it's hard to imagine finishing a leg workout with squats, and even harder to imagine the 2-3 additional exercises Kai had originally planned.
