Max-Reps: Sit Ups

Purpose: Evaluate the ability of the core and mid body muscle groups to sustain repeated contractions against body weight resistance for an extended period of time or until failure.

Equipment: Exercise mat

Procedure: Participant lies in a supine position on their mat with knees bent at approximately 45 degrees with feet flat on the floor and slightly apart. His or her hands should rest at their side flat on the floor.

Instruct the participant to tuck their chin to their chest and begin contracting anterior abdominal muscles until their upper back is off the mat and hands have moved forward approximately 5 inches. Keeping heels in contact with the mat, once the participant reaches the top of the movement he or she can slowly return their upper back to the floor and continue repetitions.  The score is calculated as the number of repetitions completed.
