Its Good For Your Game
Create right angles on swing
By T.J. Tomasi
A good way to think of your backswing is that its role is to create certain power angles between you and your golf club ― angles that multiply the force of your swing. Once you create these angles, you need to keep them intact until they release naturally.
One of the most important of these angles is the one created by your right wrist (left for left-handers) as it bends into a "hinged" position at the top of your backswing. Your wrist will do this in response to the momentum of your backswing ― if you allow it to happen.
Returning the clubhead to the ball is another story. During the downswing, there are strong forces pulling/pushing on the club that can cause golfers to lose the crucial right-wrist hinge much too early in the downswing. When this happens, your swing springs a power leak, and all you can do is deliver a weak slap at the ball that kills both your distance and your accuracy.
At first, keeping your right wrist bent (concave) longer than you're used to will feel like you can't square the clubface in time for impact. But through practice, you will realize that you can keep the hinge and square the clubface to the ball with power, not by manipulating the clubface with your hands, but through the sequence of motion as your body unwinds.
A word of caution: While focusing on keeping your trail wrist bent, make sure to allow your trail elbow to straighten naturally as you swing the club down and toward the ball.
