You step up to your ball. Your address is perfect. Your backswing is flawless. So, why is it that the golf ball does not travel as far or feel as solidly as you want? For many beginning and intermediate golfers, the act of striking the ball ends once the ball leaves the club. Yet the impact zone is not the end of the golf swing. Keep this concept foremost in mind: swinging through the ball creates greater distance for your shots. The key is to swing and accelerate the club head through the ball, rather than letting up once impact is made.
Select a mid-range iron from your bag. A five- or six-iron will suffice for improving your ability to swing through the ball.
Take your normal approach. Because you are using a mid-range iron, you'll want the ball to be positioned between your feet, keeping your feet at least shoulder-width apart.
Place the club head just behind your non-lead foot. Your non-lead foot is the foot that's farthest from the hole.
Use only your weight shift to move the club head from behind your non-lead foot, dragging it forward past the ball.
Start to accelerate your club head speed as you reach the ball, breaking your wrist, releasing, and finishing your swing.
Practice the drag move repeatedly, feeling the shift of your body weight and club acceleration as you move past the ball.
Add to the drill by starting the move from waist high in your backswing. Use the same weight transfer you used when dragging the club.
Progress all the way to a full swing, but keep the weight transfer and club acceleration in mind as you swing through the ball and begin your follow-through.
