Kneel before medicine ball. Place hands on upper part of ball on each side. Balance upper body above ball with arms extended. Straighten body and place forefeet back, away from ball on floor shoulder width apart.
Keeping body straight, lower body by bending arms until chest touches ball. Push body up until arms are extended. Repeat.
Both upper and lower body must be kept straight throughout movement. Also see close grip push-up on floor.
Resistance can be reduced by performing push-ups with knees bent on floor or placing medicine ball on higher platform. Balance can be made less challenging by placing feet further apart.
Elevate feet for greater intensity or to vary angle of exercise. Balance can be made more challenging by placing feet closer together.
