Many golfers reach a point where they find that they are no longer able to lower their score any further. This can be very frustrating, and if it's happening to you I know exactly how you feel. There was once a point where I could not seem to improve my game matter how much are practiced, and I also like quitting the game of golf altogether. When a breakthrough came when I realized that the key to being a great golfer is having a consistent swing.
In order to improve your swing, it is necessary to first break it down and look at each component involved in the swing. This will allow you to see exactly where you are making your mistakes and correct them and systematic way.
The first part of the swing you should look at is your grip. You should hold a club that awaited as comfortable for you, and make sure your hands are always facing each other. Another thing you should do is make sure you are using the exact same group every time you swing the club.
Your stance is another important element of the golf swing that many golfers overlook. Like with the grip make sure you're standing the same way every time you go to swing.
The backswing is the next part of your swing that you should be analyzing. Many golfers make the mistake of having far too much backswing, as though they're in a long drive contest rather than playing a game of golf. This is not a competition to see how hard you can whack the ball, and accuracy is far more important than distance.
Finally there's the downswing, the final element of your swing you should work on. Make sure that your body is not twisting too much or too little, as this could cause you to hook or slice the ball.
