The transition from position #3, which we call "top of backswing-torsion", to position #4, which we sometimes call "pre-impact-zap", must be achieved in a totally counter-instinctive fashion, which is a movement by the mass of the lower body instead of the instinctive move of hitting with the upper right quarter of the body prematurely. In making this first move of the downswing, it is not merely a case of learning how-what-why to make this first critical move of the downswing, (the movement of the lower mass) but more importantly we must understand the purging process that we must engage in first before we can truly experience a gain in precise golfswing achievement.
The golf swing is a most un-natural, non-instinctive, uncomfortable contrary series of moves and positions. The innate characteristics we humans have can be traced back six million years to our progenitors, who fended and fed the family with a shoulder-hand-arm striking action against the beast. This innate characteristic is still highly prevalent in all people of today. Perhaps as high as 95% of all golfers constantly are plagued by the Strike-Steer-Stare-Stall-Syndrome. Even the superstar, under maximum stress conditions, will experience the same Strike-Steer-Starre-Stall problem. When the typical golfer picks up a golf club, his "S-S-S-S Syndrome" is activated. When he faces a golf ball is ascends; on a golf course it climbs still higher; in competition it rises still higher; in fierce competition - that is, for money or the tin cup - it peakes and destroys P.T & P.S.M.
Once the fine swing has been developed to a highly conditioned response, then the key to performance is to maintain a high kinesthetic awareness level while maintaining a low emotional level. This can best be done by fully understanding the "S-S-S-S Syndrome" -- how it attacks and how it can best be controlled. It can best be controlled by purging, through a comprehensive kinesthetic conditioning and minimized while playing golf, by servicing the golfswing with the conditioning program that best minimizes S-S-S-S, the hit-impulse, through the use of the "Golden Excercise".
In going from position #3 to #4, we must be careful not to allow the #1 enemy of the golfswing, the hit-impulse, or putting it another way, the power-urge to take over. The golfer must make certain the first move of the downswing is initiated from below the belt with sitting-lateral action in the left leg. This sitting-lateral action in the left leg triggers the downswing, allowing the "Keystone" to start descending as the right leg starts to follow the lead of the left leg. There is very little pushing action of the right foot if any.
Simultaneously, the right arm retention maintains the "Keystone", (the "Keystone" is a combination of the "rod" and the "claw") during the downswing until the left hand is past the ball position. The only change in the "claw" occurs as the right hand hits, forming a rod between the right index finger and the right elbow. To avoid misunderstanding and to aid clarification, now let us deal further with the critical #4 1/2:
Make certain that in this impact position the claw is formed by the right arm, the rod by the left arm, that most of the body weight is on the left foot, that the player's head is reversing ever so slightly without any forward drift, the right knee flexed more than the left knee, with the left heel and entire foot taking most of the body weight as the right heel is raised not more than two inches.
