This is a little post.
I have said in recent posts that you should slow your swing down to ensure contact on the center of the clubface. Once you have accomplished that, swing in a way that feels the same, but in less time. Like this:
1. Before you address the ball, feel a fast, smooth, effortless swing in your mind.
2. Hold the club LIGHTLY at address. Relax everything else, too.
3. Think that it is the sole of the club that is moving fast, not your body, your arms, or your hands.
4. Relax even more during the swing.
