Adding power and distance is a goal for most golfers. Adding power doesn't necessarily mean that you will lower your score; that is usually determined by your play around the green. However, hitting longer shots off the tee and from the fairway can help your confidence and put you in a position to improve your overall game.
Address the ball properly. Concentrate on the fundamentals and don't cut any corners. That means aligning yourself correctly. Make sure your left shoulder (for a righthanded golfer) is facing the green or the target spot in the fairway. Your left foot should be directly under your left shoulder.
Bend your knees and assume an athletic position. The key to driving the ball for distance is timing in the transfer of weight from your back leg to your front leg. You can't do this successfully if your knees aren't flexed slightly.
Play the ball about one ball length closer to your front foot than your back foot when you are hitting with your driver. Because the club does not have much loft, you want to give yourself a chance to hit the ball in the air. By playing it closer to your front foot, you will hit the ball just as you begin your upswing.
Lean slightly toward the back of the tee box with your upper body as you are about to begin your backswing. By tilting your upper body, you will increase your leverage slightly and this will improve your ability to hit the ball for distance. This technique of tilting toward the back of the tee box is called the "power lean."
Rotate your hips to get your swing started. You may want to hit the ball harder and farther, but there is no point in increasing the tempo of your backswing or approach to the ball. However, when you come through the ball with your hands, you must snap your right hand on impact with the ball in order to get extra distance. A steady and smooth swing will suffice, but to get extra power snap your right wrist on impact.
Tips & Warnings
Practice the power lean and the right wrist snap whenever you go to the practice range.
