Headcover Drill

Another important aspect of the one plane swing is keeping the arms passive or connected to the body, allowing the body to control the golf club rather than relying on the arms and hands to do so. This concept of body-driven rotation is at the heart of efficient, powerful ball striking, and a simple tool like a headcover can transform how you feel the correct motion.

A very simple way to start to correct overactive arms in the swing is to stick a headcover under your lead arm and hold it there as you make some swings. For a trail-hand dominant golfer, the lead arm is the one closest to the target — the arm that needs to stay close to the chest to maintain proper connection throughout the entire motion.

You’re looking for a feeling of connectedness. You don’t have to clamp down on it tightly, but if you feel like you have to work hard just to keep it from falling out, this drill is probably exactly what you need. That struggle is your body telling you that your arms have been doing too much independent work, separating from the core rotation that should be driving every shot.

Start out by putting the headcover under your lead arm and then just rotate your body back and through. Feel how the arm stays pinned against the chest as your torso winds and unwinds. So far so good!

Of course, when you go to make a full golf swing your arm will work a little bit across your chest and a little bit back. This natural movement is fine — what you want to eliminate is the arms separating aggressively from the body, which is the root cause of so many swing faults including early extension, loss of posture, and casting the club.
