With your irons, the target of the swing is not the ball, nor the green way out there. It’s the ground right in front of the ball. You want the bottom of the club to make its first contanct with the ground the tiniest bit beyond the front side of the ball (yellow line).

That promotes ball first-ground second contact, and helps prevent hitting fat.

Now how do you do this? There is a very simple way, one that does not involve changing your swing one little bit. You do it with your mind.

Before you take the club away, look at the ground where that yellow line in the photo is, and tell yourself to hit the ground on that very spot. Your unconscious mind will say, “Yes, sir!” or “Yes ma’am!” as the case may be, and direct your swing to do just that with no conscious effort on your part.

Easy.
