Correct your backswing in three steps. One of the reasons you might not hit the ball far enough is because your backswing simply isn’t long enough; therefore, you don’t have enough time to create the acceleration necessary to hit the ball the distance you would like to hit it. What you want to try to do is increase the length of the backswing in order to give you time to accelerate the club so that you can hit the ball farther. A real good drill to help you to understand how to create that distance is to understand that there are three parts that must make motion: (1) one part is the turning of your body; (2) one part is the swinging of the arms; and (3) one part is the cocking of the wrist. So a real good exercise to feel all of those parts used the right amount is to start by: cocking your elbows in front of your body; then cocking your wrists back as far as they will go; and then creating a turn. This will give you a full backswing, which allows you enough time to get the club accelerating into impact to hit that ball farther.
