The hip slide, weight shift, hip drive or whatever you want to call it is one of the most important, yet overlooked elements in the golf swing. Golfers have become so brainwashed against any form of lateral movement that I believe the vast majority of us are trying to stay as quiet and centered as we possibly can. Here are a few interesting points about hip action:

The downswing does not mirror the backswing. There should be no lateral hip motion in the back swing, while the downswing must have a good measure of shift towards the target. The weight shift to the front foot is entirely attributable to the hips gliding towards the target in the downswing. The head and upper body must remain over or slightly behind the ball as the hips shift, thus creating body curve. Hip slide creates the room necessary in the downswing for the arms and club to drop to the inside. Too much spin or rotation from the top and you can only come over the top. Not only does the hip slide create room for the arms to get to the inside, but it also positions the weight so that the ball can be struck with a descending blow. The weight must be on the front foot for any golfer to consistently hit down on the ball. This video from my
