Attach two medium bands to a middle anchor point. Facing toward the anchor point, get into a Squated Stance and grip the handles with the palms facing toward the body. Add an appropriate amount of tension in the bands and begin the exercise with your hands in the rib cage and engaging postural muscles. Perform the exercise by extending the arms fully from the Squatted Position and pulling the handles back into the body so that the hands end up back at the rib cage. Tip: Thumbs facing up when hands are pulled into the rib cage and thumbs facing each other when arms are fully extended.
