Rely on a proper posture, get the right golfing shoes and focus on aligning with the ball. Why do you need a strong posture is because without it you could twist at an in appropriate moment resulting in your incapability to hold the club properly. What happens when all these things come together is that it spoils your attempt at a good back swing. This is your first line of defense.

How would you detect whether your posture is right or not? Then compare the proper stance with the exact way that you are standing. If this is not an option for you, look into some lessons, which will allow you to work with someone to truly master your stance. A good set of foundation skills should be at the base. If you have the ability to work with a golf instructor this is going to be the best way since they can be much more honest with you about the flaws in your stance than you will be with yourself.

Your next set once you have corrected your stance is to look at the problems with your grip. It is when you overextend your grip or hold the club the wrong way. Unless you hold the club properly, you can never master the art of a good back swing. To get it perfect, you would surely go on trying. A little alteration in the hand position could provide unprecedented results in the outcome.

The last point of consideration while you are working on improving your back swing, is that you must pull he club from the ball before it is moved off the ground. Generally players make the mistake of doing both these acts of pulling and lifting the club at the same time. This not only destroys movement but creates an off-center hit. When you pull the club before lifting it, you could notice great improvements in the game instantly. This neither hard or complicated thing to do. Your back swing would improve drastically if you make that extra effort to pull the club before lifting.
