The 'Inside Approach.' It's a little tripod looking device that forces you to swing from the inside. You must swing under an 18 inch length of cushion, which is lined up with your target. It costs around $60, but is relatively easy to build yourself. Initially I believed it only benefited my driver, but after the shanks arrived, it has helped to curb them by eliminating my over-the-top move with my irons as well. Good luck.
