"Go ahead and try it. Why is is that the great majority of average golfers keep their head still while pros move their head? Jim McLean did an article on this called the Y factor. Tour players moved their head on average 3.6 inches. Amateur average was .6 of an inch. Your feet are spread apart. In doing so keeping your head still will allow you to create the first axis in the backswing. If you do not create this axis your whole body will be leaning left at the top. If you turn you will come way over the top. The only way you can get the club to come down is by shifting laterally. Now you will be blowing it right. Watch: Move Head:
