While all this has been happening, the right leg has not moved except torsionally. Here, I am afraid, I must allow some other portions of the anatomy to intrude on my sectional analysis, but I shall only do that in so far as I cannot keep them out, for I have a very definite object in considering each portion of the machinery by itself.
As the left knee moves in towards the ball it naturally pulls the left hip joint after it. The twisting movement of the body, commonly mis-called rotation, is supposed to take place with the spine as an axis. It follows then that this pulling forward of the left hip joint throws backward the right hip joint. As the right foot is planted firmly for its full length on the earth now and until some time after the top of the swing is reached, it follows that the right leg is twisted at the top of the swing.
It is this torsional strain that has been mistaken for weight and that has led to the great mistake made by the most famous professionals and writers in this most vital matter.
Now without considering the hands or arms we have arrived at the top of the swing; and let me say now that although I have never even thought of teaching the drive this way in practise, it would probably be much sounder and productive of better results than the methods generally used.
