Is it possible to keep your head completely still when you swing the club? If so, is it beneficial to do so? Well, the answer is no.
This old golfing myth is misleading as keeping your head still is one of those classic lines used as an excuse for a bad shot.
Basically, if the head moves unnecessarily in the swing, it can create problems with consistency and ball striking.
While it doesn't create too many problems in the backswing, it's in the downswing and through impact where the real problems arise.
Given the speed and momentum created in the downswing, once you've hit the ball and you're moving into the follow-through, your head will naturally move and face your target as you complete your swing.
If your head didn't move, you would end up with a downswing where your body stops turning and you would "flick" at the ball with your hands to generate any meaningful power which makes for a very inconsistent game.
Your head and spine act as the base that the body moves around in the swing.
Keeping both head and spine in a consistent position will help to create a repeatable action.
However, you just can't keep your head still, as you'll notice, if you look carefully at where the game's top player's head is at address compared to where it was at impact.
There is a definite "dipping" of the head, which could be as much as a couple of inches if you look closely.
This happens automatically when we try to gain power in the downswing.
Shifting our weight aggressively into the left side and left foot created a "squatting" action which inevitably makes the head being lower at impact than at address.
Out of Bounds: "The real measure of your wealth is how much you'd be worth if you lost all your money." This didn't go down too well when I said this recently to a mate who was paying up after a recent game.
