Golfers who get elaborate in their swings usually aren’t consistent. The true golf swing is a very simple affair when you’re playing well: you swing the club back, you swing the club through, and the ball goes where you’d like.
People often worry about their weight shift. A weight shift gets complex when the head starts moving about – that’s more of a slide than a shift, and it causes consistency problems.
The next time you’re on the range, try to keep your head absolutely still. I like to imagine a giant rod going down the back of my head, through my spine, and into the ground. I turn around this giant rod – my left shoulder working under, my right shoulder working around the top. I have no choice but to maintain both my spine angle and position through impact!
In reality, the best pros move their heads and their spines a little, but far more than the average amateur golfer thinks is necessary. Stick a giant rod through your spine next time and see how your consistency improves.
