There are three essential parts to any complete golf game. If you can bomb it off the tee and play sharp around the green, you have two of the three essentials licked. Long irons, on the other hand, are often approached with trepidation. The small club face and delofted status can make long irons rather temperamental and unpredictable. But, there are some basic steps you can take that will help you increase your success in the long-iron game and put it all together.
Address the ball bending at the waist. One of the first steps is to make sure that your spine angle is correct. So, when you approach the ball, get in your normal stance and bend at the waist to meet the ball, but keep your spine straight, as opposed to hunched.
Keep your weight between the balls and heels of your feet, slightly back from normal.
Start your backswing, making sure that you keep your head at the same level as address. The swing is more of a sweep, as opposed to a more aggressive, downward cut like you might have with a short iron.
Try and connect with the inside half of your ball upon impact. As you move to lower irons, hitting the inside half--the half closest to you--becomes more important with the smaller club face.
Hit the ball on impact. Beginner and intermediate golfers tend to hit the ground before or at the same time as they hit the ball. For a really solid iron shot, it makes all the difference to get solid contact on the ball and then hit the ground.
Follow through, keeping your body still and your head level.
