USMC Crunches: PFT Rules
MARINE CORPS PHYSICAL FITNESS TEST AND BODY COMPOSITION PROGRAM MANUAL
The goal of the abdominal crunch event is for a Marine to execute as many proper and complete crunches within the prescribed time limit. The procedures are:
(1) 2-minute time limit.
(2) On a flat surface, Marines will lie flat on their back with shoulder blades touching the deck, knees will be bent, and both feet will be flat on the deck.
(3) The arms will be folded across the chest or rib cage with no gap existing between the arms and chest/rib cage. Both arms must remain in constant contact with chest/rib cage throughout the exercise. A single repetition consists of raising the upper body from the starting position until both forearms or elbows simultaneously touch the thighs, and then returning to the starting position with the shoulder blades touching the deck.
(4) The buttocks will remain in constant contact with the deck throughout the event. No arching of the lower back or lifting the buttocks is permitted.
(5) An assistant may be used to hold a Marine’s legs or feet, at or below the knees in whatever manner that is most comfortable for the Marine. Kneeling or sitting on the Marine’s feet is permitted.
(6) A repetition will be counted when an accurate and complete abdominal crunch is performed.
