PUSH UPS ON TWO FITBALLS

TIPS: The key of the exercise is quality over quantity. The trick is to perform the exercise using proper form.
STARTING POSITION:
Place a fitball in front of you and another fitball behind you. Lie on the fitball face down placing your hands slightly wider than shoulder width apart while holding your torso up at arms length. Now place your feet on the other fitball and straighten your legs. Keep your shoulders far from the ears retracting your shoulder blades. Contract your pelvic floor and core while keeping your body straight.
MOVEMENT:
Start lowering yourself by bending your elbows until your chest almost touches the fitball while you inhale. Press your upper body back to the starting position tensing all your body muscles while you exhale. Make sure your shoulder blades are always retracted.
