The stability ball pushup is an advanced progression of the traditional pushup that strengthens the chest, shoulders, and triceps. Performing the exercise on the stability ball, an unstable surface engages the core throughout the entire range of motion.
Lie face down on the floor and place your hands apart from each other holding your torso up at arms length. Place your toes on top of the exercise ball.
Inhale and lower yourself until your chest almost touches the floor. Keep your body straight.
Exhale and press your body back up to the starting position, using your pectoral muscles. Repeat.
