Lateral Movement and Fat Shots
For those of you who have a tendency to hit the ball on the top of the club, that is to swing underneath the ball, hitting fat shots or pop ups when the ball is on a tee, one of the major causes of that is the fact that you might have too much lateral movement in your swing.
Lateral vs. Rotary Movement
If you move side to side, the bottom of your swing changes with the center of your body. What you would like to do, instead of having side-to-side movement in your swing, is to have rotary movement. Fell like you are turning within a confined space. Turn back to the left and when you come through turn back to the right, reducing the amount of side-to-side movement in my swing.
A good exercise for those of you who have this problem is to set up what I have here. I have two old shafts that I have stuck in the ground on the outside of my feet. You may not have shafts, so you might want to use bag stands by each side of your legs, anything to tell you if you moved too much sideways. For instance, if I over shift to the right I can feel when the shaft touches my leg, or if I shift too far forward I can feel when that shaft touches my front leg. What I want to do is to turn inside of these shafts, like the old turn inside a barrel image. Let me demonstrate. As you can see, I turned back and I turned through without hitting the shafts. This is the way to get solid contact.
