The nine o’clock preset drill is a great drill to improve your swing. It’s very simple, you’re going to take your set up, hinge the club up in front to you, lead arm is parallel to the ground, widen out, trail arm is in connected to your side, and your wrists are fully set at this point. Then from there, all you need to do is a full body turn and come down the same way and you’re going to be gold.
When you get in the nine o’clock position you will find the club gets in a much better position at the top and then your body and arm swings going to match up beautifully on the downswing too.
