The key to consistency is to maintain your balance and use a smooth rhythm.
If you rush your swing you will lose your balance and the end result is inconsistent contact and poor ball flight. Outstanding ball strikers are rarely off balance at impact and their rhythm is the "glue" that bonds their positions and movements. Often their swings seem effortless and they, "swing easy and hit hard." Great rhythm allows you to properly sequence your body motion and arrive at impact in a position of leverage and power.
If you want to be a more consistent ball striker, you must understand how the body should be balanced in four key positions.
Although your spine is tilted away from the target at address, you should have your weight evenly balanced between your right and your left foot with your middle and long irons. Also, you should feel your weight evenly balanced between your heels and your toes, roughly on the balls of the feet.
TOP OF BACKSWING
As you pivot to the top of the back swing, your weight moves into the inside of the back foot. You should feel approximately 75-percent of your weight on the back foot and 25-percent on the front foot. The weight must never move to the outside of the back foot.
By the time you arrive at impact, approximately 70- to 75-percent of your weight should be shifted onto the front foot. Your head must be behind the ball and your hips must shift forward approximately 4 inches past their starting position. This increases the spine tilt by at least double.
At the completion of the follow through, you should have the majority of your weight - about 90-percent of it - on the outside of the front foot.
