Control forearms to hit accurately
There are few things that will disrupt your ball flight more than too much forearm rotation. There are two bones in your forearm that rotate over each other to allow the palm of your hand to turn skyward as well as to the ground. These are handy movements to have in your survival arsenal, but if they are over- or underdone during your golf swing, they cause trouble.
The reason is that your forearms rotate the clubface, which is responsible for 85 percent of your accuracy. If it’s your goal to hit consistently accurate shots, listen up.
The key to accuracy is to cock your wrists without rolling your forearms during the takeaway. It’s important to understand how to set your lead wrist without spinning the shaft, so use this drill: Extend your lead arm straight out and aim your hand at a target as if it were a pistol with the hammer (your thumb) cocked and ready to fire. Your wrist should be directly in line with your forearm. Now take your address position, and practice cocking your wrist the same way, so the club sets upward, making sure it stays in line with your forearm.
To keep your forearm under control during your takeaway, cock your front wrist (per the drill) by moving your thumb back toward your lead shoulder as you swing your arm across the middle of your chest. Here, the shaft of your club points between the target line and your toe line. Note that your arms move up and your wrists cock up, but the forearm doesn’t spin the clubface open.
The guiding concept is that the arms and wrists do the “up and down” of the swing and the body does the “around,” and they don’t get into each other’s business. Thus the amount the club travels behind you equals the amount of body rotation, and the amount the club goes above you equals the arm/wrist elevation.
And here is the key point: As you rotate your body, the momentum tilts the shaft so that it now points at the target line, aka on the plane angle. You don’t force the shaft to rotate, but you allow your friend momentum to do it, and when momentum is your friend, the clubface twirl that troubles so many golfers disappears.
Summary: Cock the club straight up, then let the rotation of your
body tilt it onto the swing plane angle. And remember: With a quiet face comes consistency, and you quiet your clubface by cutting back on your forearm rotation.
