Then bring your knees towards your chest with the exercise ball. 3.) Hold this position for a count then returning back to the starting position. 4.) On the return of the exercise ball to the starting position, bring your chest down to the floor in a push-up motion. 5.) Return back to the starting position and repeat for as many reps and sets desired.
