Golf Swing - Setup - The Chin
Too Up

Too Down

Use Fist as Guide

After you address the golf ball there is a check-list of things you need to go through to make sure you are ready to take off. I am not going to tell you the position of the chin (#33) is the most important- however, it ranks up there for sure. The chin controls what happens to the shoulders in the backswing. If the chin is down in your chest at address (#32), the shoulders will have a tendency to pop up in the backswing. The right shoulder will NOT turn out of the way to make room for the arms to swing around. If you continue to leave your chin down in your chest you might have some success with the shorter clubs, but the long clubs will be very difficult to hit. You can get away with the arms swinging up and down with the short clubs, you might not be so lucky with the longer clubs.
If you are going to make the change you should do it now and make the change with all of the clubs. It will pay off with crisper iron shots and more solid tee shots.
As you prepare to address the golf ball the knees are slightly flexed, the spine is long, the shoulders are back and the chin is an extension of the spine. For those of you who wear bifocals or have played with your chin down in your chest for the past 20 odd years, this is going to be somewhat of an awkward feeling when you lift your chin up. If you wear bifocals this might be close to impossible to accomplish. For the rest of you who do not wear bifocals, the party is over, no excuses, get your chin up.
