Forearm rotation (pronation and supination) in the golfswing fact or myth
I have heard a lot said on the subject of pronating and supinating in the golf swing.The pronator muscles in our forearms turn our hands palms down from the elbows and the supinator muscles in our forearms turn our hands palms up from the elbows. Both with no turn in the elbows (shoulders). In the golf swing as the rule these muscles are simply stabilizer muscles. Even though"some" may start their back swing with this forearm rotation, arm turn from the shoulder quickly catches up in the back swing. Try this. In a standing position hold your left arm straight out and level in front you with your thumb up. With a relaxed arm turn your hand clockwise from your elbow so your thumb now points straight to your right. Swing your arm right well past your right shoulder and then bring it back to the straight out position. Now if you turn your arm from your shoulder so your thumb points up again you will find your arm in the original straight out position. I'm sure we do rotate the forearms at times, to increase a draw or a fade maybe to add or subtract a little height to a shot. Flipping the clubface at impact may be the result of supinating the left and pronating the right into impact, rather than a full arm turn. Any ways I am trilled to have this forum to discuss this and the many other golf related topics.
