Opening the Front Shoulder too Early in the Downswing
by Jack Gibson, PGA

I never liked the idea of just thinking about “front shoulder,” “left hip” or any other thought that seems to forget that you can’t move either independently without also moving the opposite shoulder or hip. Presuming we are working with a golfer who has most of his parts connected, it is more productive to concentrate on the golfer’s dominant side movement when trying to make a correction. For a right-handed golfer, for example, learning to swing the club head down and toward the golf ball with the right hand and right arm is a simple and effective way to eliminate any “opening of the front shoulder” until the golf ball is well under way.

So, what is my favorite drill for opening the front shoulder too early? I suppose it would be to simply learn to swing the club head back and through with the dominant hand and just let the body respond to that swinging motion, as was taught by the great teacher Manuel de la Torre.
Try it. It will work and improve the golf swing of anybody. And don’t worry about your front shoulder.
