ITS CRAZY.The instructor even does it with them, they do like 100 over dips with only 1 min break inbetween.The instructor does it like its nothing to him.
While the soldiers(some are like going to die anytime, a lot start doing partial dips after some time already)While the instructor just keeps going at it like a mad person.
