Exercises, nah, that is not an exercise. That is me trying to figure out how wide my feet should be at address. One of the keys to good balance is finding a width that allows you when you finish for your back leg to catch up to your front leg. Here is what that means. I like to teach a drill Jerk Back and Slam. What is jerking back? The left leg? What is slamming? The right thigh into the left thigh. I will show it to you from a couple of different angles. If you get too wide no matter how good a job you do of jerking back and slamming your right leg can never catch up to your left. You can see my left leg over here. In a good finish I can only see if I am watching you hit one thigh, the back one. Watch. I narrow my feet I make the same move and as I turn through it you see my right thigh and you have to ask yourself where did John's left thigh go? Well the answer is it is behind my right one. Her is why. During the forward swing the left knee jerks back towards the heel, the right thigh slams into the left thigh. So if I handed you a million dollar bill and you put it between your two thighs it is yours as long as it is still there. As soon as it touches the ground it is mine. Well, most of you being pretty smart you will probably walk to your next shot like this because no one wants to lose a million dollar bill. Point being in a good golf swing the lead led jerks back, the trail thigh slams into your lead leg, and from your knee cap all the way up to your crotch the two thighs are squeezed together like me putting my two palms together. Now I am in the ultimate balance position. Jerk Back and Slam. The width effects it. Your ability to move your legs correctly effects it. The speed of your swing will be increased dramatically because you are using your legs more efficiently. End result, you are going to hit the ball much further and it is going to make a lot more noise. That is nice.
