The guy in the hotel gym wants to be a boxer. Running on the treadmill, he flicks a flurry of jabs and hooks. Then he turns the speed up all the way and sprints, sprints, sprints.

He absorbs a massive beating. A woman hops off her stairmaster to help. Here’s this guy trying to be a boxer and he loses his first fight to a treadmill.
