Chapter # Eight - The Arms
THE LEFT ARM - THE RIGHT ARM
THe LEFT ARM at start up, is straight, tension free and pointing from the shoulder to a point slightly behind the ball.
THE LEFT SHOULDER is the center of the left arm and club swing. The motion, caused by the relationship between the left shoulder, left arm, clubshaft and clubhead, forms a circle. The left shoulder is the center of this circle. The left arm and the club form the radius of this circle. The Clubhead moves along the arc of this circle. The golf ball rest on the arc of this circle.
The left arm is caused to remain straight by the outward pressure of the right palm against the left thumb. This relationship of the right hand and left thumb is called EXTENSOR ACTION. This extensor action joins the hands together and allows the two arms to work together. As long as this outward pressure against the thumb is maintained, the left arm will remain straight and will be tension free, from address to the top of the backswing, returning to impact.
The left arm is caused to be straight by the extensor action, from start up, to the top of the backswing. During the downswing into the forward swing, CENTIFUGAL FORCE takes over and keeps the left arm straight until the momentum of the clubhead causes the left elbow to fold. This folding action allows the club to swing over the left shoulder and behind the back. At this point the club can be used as a balance pole to help maintain good balance.
When ever, the left arm returns to a position paralell to the ground, during the down swing, it should also be paralell to the target line. When the left arm is parallel to the ground, it will be pointing down the INTIAL FLIGHT LINE of the ball. If it is pointing right, the ball will start right. If it is pointing left, the ball will start to the left.
THE FOURTH PRESSURE POINTof the golf swing is the contact point of the left arm against the chest. The greater the contact pressure of the left arm against the chest is maintained, the greater amount of body rotation that can be utilized by the swing arms; the greater the power transfer from the rotaing body through the arms into the clubhead. The lesser the pressure of the left arm against the chest, the slower the arms will be able to be swung, the lesser power transfer.
THE RIGHT ARM THE RIGHT ARM at address is slightly lower than the left arm and is slightly flexed. The upper right arm is in contact with the chest and is vertical to the ground.
The right arm is caused to be moved by the intitial motion of the left hip away from the ball.
This intitial horizontal motion of the left hip, 45 degrees away from the target, around the right hip, causes the right forearm to move away from the target. At the completion of this horizontal movement of the left hip, the left arm is pointing down the stance line parallel to the target line. The right thumb is pointing directly down a line away from the target, parallel to the target line. The shaft of the club is parallel to the ground, parallel to the target line parallel to the stance line. The right forearm is parallel to the ground. Both the right and left hands are vertical to the ground. The hands are at their lowest point in relationship to the ground. At this point all HORIZONTAL body motion away from the target stops.
All motion of the hands and arms from this position to the top of the backswing is VERTICAL. All the motion of
the down swing, which returns the hands to their low point position is vertical. This vertical motion of the hands and
arms to the top of the backswing is caused to happen by the cocking of the right elbow towards th right shoulder.
This cocking of the right elbow causes the hands to rotate to the right so that the back of the right hand is flat against the swing plane.
This cocking of the right elbow causes the left wrist to cock.
This cocking of the right elbow causes the left arm to be raised to it's cocked position.
The extensor action force of the right palm exerted on the left thumb causes the left shoulder to be rotated around the spine to its position at he top of the backswing. This position is 90 or more degrees away from the target. Since the right shoulder is connected to the left shoulder, it is also caused to be rotated 90 degrees or more towards the target. At the top of the backswing the right forearm is vertical to the ground. The right upper arm is horizontal to the ground.
The Downswing begins by releasing the tension in the right elbow. The right arm goes from a cocked position at the top of the downswing to a fully extended straight right arm shortly after impact. The right arm then caused to fold as centrifugal force carries the club over the left shoulder.
