Attach two medium bands to a high anchor point. Facing away from the anchor point,  get into a Half Kneeling Stance and grip the handles with the palms facing down. Add an appropriate amount of tension in the bands and begin the exercise with your arms retracted pressing position with the elbows tucked to the sides. Perform the exercise by pushing the hands down and away while you contract the abdomen muscles, bringing the rib cage down toward the waist line. Then return to the starting position. Tip: Make the exercise a little tougher by extending the arms and holding them in front of your chest.
