One repetition is counted when the forearms touch the thighs, and they return to the start position. Marines cannot bounce or arch their lower backs, and their buttocks must remain in contact with the floor. The Marine Corps modified the sit-up to provide a better evaluation of abdominal strength and reduce the potential for neck and back injuries, Pappa said. The number of repetitions to achieve the maximum score increases July 1 from 80 to 100 for both men and women. The Navy's version, the curl-up, mirrors the Marines' with one variation.
Sailors fold their arms across their chests with hands touching the upper chest or shoulders.
The Navy and Army use push-ups to test upper body strength. Soldiers and sailors have two minutes to do as many push-ups as they can. New pull-up guidelines went into effect January 1997. Personnel must sit with legs straight out, feet together and toes pointed up. Without bouncing or lunging, personnel must touch their toes with the fingertips of both hands and hold the position for one second.
