Alignment is one of the most important, yet the most overlooked fundamental of golf. Your forearms, eyes, shoulders, hips, knees, and feet should be parallel to the target line. Just think of a railroad track. The body should be on the inside rail and the ball outside.
You should take at the position of your feet. Your feet should be just the same as your shoulder width when it comes to middle irons. For short irons, your stance should be narrower by 2 inches. For long irons, your stance should be 2 inches wider. Your target-side foot should flare toward the target, and the back foot should be square. Some of the things which help determine proper foot replacement are your body rotation speed and flexibility.

The placement of the ball will not stay the same. It changes with each club you use. For long irons, the correct ball position is towards the target-side foot from the center. For middle irons, it should be toward the target-side foot from the center and for short irons, it should be just in the center position. Learning the correct golf swing is one of the important factors that you must focus on playing golf.
When swinging, your weight should be balanced on the balls of the feet. Your feet should not be concentrated in your toes or your heels. A lot of people make this mistake, and it affects their swing in a very big way. If you are doing short irons, your body weight should be 60% on the target side. For middle irons, your weight should be equal on each foot. Lastly, for long iron, 60% of your weight should be on the backside foot.
How you position your body can have a great effect on your swing. Therefore, you need good posture. Your knees should be slightly bent, and they should be directly above the balls of the feet. This will give you balance. Your body should be bent at the hips and not in the waist like most people normally do. You will know that you have the correct posture because your buttocks will protrude. There should be a right-angle relationship between your shaft and your spine. This helps when you swing the club. Your vertebrae should be straight, and there should be no bending in the spine, especially at the middle. You can observe this to the most professional golfer as they know and master how the proper position to achieve the correct golf swing.
Your hands should hang forward in the direction of your zipper. The distance between your hands and your body will depend on the club you are using when swinging. Generally, your hands should be just the width of your palm away from your body when using middle and short clubs. For long clubs, your hands should be the length of your palm away from your body.
Now you know the basics to achieve the correct golf swing, you should practice it. Over time, you will see that your swing will improve, and your game will be a lot better. Click here to get more info about correcting golf swing.
