STARTING POSITION:
Place a fitball in front of you and other fitball behind you. Lie on the floor face down and place your hands on the fitball 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 the shoulders far from the 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 fitball while you inhale. Press your upper body back to the starting position strengthening you body while you exhale. Make sure your shoulder blades are always retracted.
TIPS: The exercise key is quality over quantity. The trick is to perform the exercise using proper form.
