One of the best things I am known for is the X-Factor. Now I wrote a series of articles for Golf Magazine in 1992 called The X-Factor. Later on I did a tape, The X-Factor Video and then the book. So I spent a lot of time speaking on the X-Factor all over the world, and what the X-Factor is, is really how the body moves in the swing.
What is the Basic X-Factor Coil?
What moves first, how much do you turn your shoulders, how much do you turn your hips, what are the knees doing, what are the feet doing, it is the entire body. We also look at the arms and how they work with the body. Let me give you the basic X-Factor coil, the first article I wrote, and that was the X-Factor Power Coil, how to gain power by making a more powerful backswing.
Seperation Between the Shoulders and Hips
What I found was that the average person tends to make a big turn but it is a weak turn, and what I mean by that is the lower body and the upper body turn in tandem. So you end up with a pretty big turn, your arms might collapse a little bit, your left knee travels a lot, you might have poor balance, but mainly the hips and the shoulders are almost together, or equal.
What we found by studying Tour professionals and the longest hitters is that they get big separation between the shoulders and the hips. So it is really not how much you turn but rather how you turn. What you want to have happen in your swing is to get to a 90-degree shoulder turn if you can, but 80, 90 or 100, anywhere in that kind of gap there is fine, it is just that you want the lower body to resist.
Shoulder Turn vs. Hip Turn
As you go away, what I am looking for is that the shoulders far out-turn the hips. We would like to see a gap of at least 30 degrees between the shoulder turn and the hip turn. So when you go to the top try to check if this turn of the shoulders, put a line across your shoulders, is quite a bit more than the turn of your hips. That is the simplest way that I can give you the basic ideas of the Power Coil.
