PUSH UP 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:
You need to find two fitballs and place them together in front of you. Lie facing down and placing your hands on the fitballs slightly wider than shoulder width apart while holding your torso up at arms length. Support your weight on your toes. Keep your shoulders far from your ears retracting your shoulder blades. Contract your pelvic floor and core while keep your body straight.
MOVEMENT:
Start lowering yourself by bending your elbows until your chest almost touches the fitballs 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.
