Rhythm and balance are essential for a good golf swing. Once you've spent some time on the basics, you can improve your swing even more by paying careful attention to your rhythm and balance.
Eric Johnson demonstrates some great drills that will help you improve the rhythm (and therefore the balance) of your swing in his video "Fairway Woods Swing Rhythm" on PGA.com:
- Count it Out: Your second grade "one-and-two-and-three-and-four-and" rhythm skills will serve you well with this exercise. Begin by repeating in a slow, steady rhythm "One-one-thousand, two-one-thousand." Once you've got a steady beat, practice swinging back on one and down on two. Simply counting through the rhythm of your swing will really help you become aware if you're rushing part of your swing.
- Two Balls: Place two golf balls on the ground one directly behind the other. Now, slip your iron between them and swing. If the back ball goes hurtling off into the far distance, you're rushing your swing. To improve your rhythm, practice until the back ball rolls just a few feet.
