Use a bag towel to promote stronger strikes

STEVE ASTLE

Fold your bag towel into thirds and lie it across your target line, behind the ball as shown. Address the ball so your trail foot is opposite the middle of the towel. This places the ball three or four inches ahead of the towel for a mid/short iron. All you have to do with this drill is miss the towel coming into impact. Missing the towel means powerful lag retention and a squeezing attack angle. Contact with the towel provides painless yet pronounced proof of any casting or flicking at the ball.
