Address the Ball
In order to give yourself a chance to build a good swing, you need to start off with the correct address. Make sure your left shoulder is facing the target. Your left foot needs to be directly under your left shoulder. Your feet should be shoulder-length apart and your knees should be flexed slightly. Play the ball midway between your front foot and your back foot.
Rotate your hips to the right (for a right-handed golfer) to get started. Many golfers will make their first move with their hands and arms and that is a mistake. Your hips are the engine of the golf swing. Rotate them to the right and then let your hands and arms follow. Your backswing is completed when your hands and wrists have reached shoulder level.
After you have rotated your hips to the right on the backswing, rotate your hips back to the left to begin the downswing. Once again, your hands should follow. Your hips need to get all the way through the hitting zone before your hands come through the ball. Once your hips have cleared, your hands will come through with speed and purpose.
Moment of Impact
Your left hand will take the club into the ball and it is responsible for the accuracy of your shot and a good portion of the power. However, once you make contact with the ball you need to snap your right wrist to get maximum power and distance on your shots. By snapping your wrist, you should be able to get an extra 15 to 20 yards every time you hit the ball off the tee or with a fairway wood or long iron.
Many high- and medium-handicap players don't finish their swing correctly. Instead of keeping their heads down all the way through contact and bringing the club up to shoulder level, golfers are anxious to see the results of their swing and they pick their heads up and don't finish. Resist the urge to look at your shot before you finish your swing. Your playing partners will tell you where the ball went. Finishing the swing will give you a much better chance to have excellent results.
