One of the most common problems I see with high-handicap golfers is improper weight transfer. Many have what is called a “reverse pivot.” Quite simply, if most of your weight is on your back foot after you swing, you have a reverse pivot. This improper weight shift causes an inconsistent golf swing resulting in one of the following: topping the ball, hitting the ground before the ball, ball contact on the toe of the club, and sometimes even missing the ball. Even with decent contact, distance and direction will suffer.
In your backswing, some weight should shift to your back leg, but in the downswing is where the proper weight transfer forward must happen in order to make solid contact. The shift continues through impact and follow-through. If done properly, you’ll end up with most of your weight on your front foot, and your belt buckle facing the target.
Taking practice swings without a ball in front of you will reinforce the feeling of weight transfer. You can practice this further by taking a backswing but stopping it when you cannot turn your shoulders and hips anymore. Then note the feeling of your weight being shifted onto your back leg. Do this several times; the feeling will eventually become natural. Once it does, you can then complete your downswing, feeling the weight moving from your back foot over to your front foot. As you practice with complete swings, your rhythm and tempo will become smoother too.
