Or most difficult wrestling workout.
I forgot the name of the exercise, something like "Walking Dead Man's 20" but anyway, Max Meltzer attempted it during the break. What it is, is you mark off approx 30 feet. You go down and do a pushup. You briskly walk in a straight line back the other way 30 feet, turn around, do two pristine pushups, and keep doing it until you can't go any further. Max did 19, but the pushups had gotton so bad by 14, not sure the other five would've been counted in the wrestling room.
