My son is learning how to play golf. He he didn't start until he was about 30 years old. Best to start when you're about 10, and I tried, but he was 10 in the heyday of Michael Jordan, and basketball won out. My son is fairly athletic and hits the ball a long way, but neither he nor I have any idea of where it's going to end up most of the time. The reason for that, and the one thing that he is struggling to learn, involves his left wrist. This post is not about him, though. It's about over half the recreational golfers I play with who do the same thing he does. They flip. In an earlier post, I talked about pronation and supination. This is one of my most-read posts, because it is something that Ben Hogan went into at length in his book, Five Lessons: The Modern Fundamentals of Golf. The Hogan mystique makes amateurs think this is the magic move that if they get figured out, will change everything. For once, they're right. It means simply this. At impact, the cup (backward bend) in the left wrist MUST BE MAINTAINED. That wrist must not be straightened out at that moment, and it must certainly not be bent forward (flip). Pronation means to turn downward, and supination means to turn upward. Think of supination : sky. If you let your left wrist straighten out or bend forward before impact, the left palm will be turned upward (facing the sky) and this is the move that just ruins everything. You just can't do this and play anything close to good golf. Supinating the left hand is a natural move for many golfers, though. Because you are left-handed, you want to get the ball in the air with that hand, and you likely use a throwing motion which ends up bending your wrist forward. Many golfers do this because they learned how to throw a baseball before they learned how to swing a golf club. When you throw a baseball, the wrist bends forward after you release the ball in the same shape as when you supinate your wrist (incorrectly) in the golf swing. Hitting a golf ball, though, is not a throwing motion. It's a hitting motion. If you want to do something with your left hand, think of driving the ball forward with the palm of that hand. The club will get the ball in the air. Drive that ball forward, and you do that by keeping the left palm facing the target. At impact, your left palm needs to be in such a position that if there were a rod coming straight out of it, the rod would point right at the target. The hard part about learning this is that you might have to change a firmly established habit of turning that palm upwards. Fortunately, that is easy to do if you are willing to put in the time and can accept that it might take several months for the changeover to be complete. Stand at address, with no club in your hand, and swing your left arm across your body so the left wrist is centered. Now bend the wrist so the left hand points straight down to the ground (Figure 1, below). Notice that my hand is curled as if it were gripping a golf club. www.therecreationalgolfer.com. It will change everything about the way you play.
