Much power can be gained simply by learning the correct sequence of body movements that create a linked chain of levers. Once the spine is slid into position with the head remaining centered and the bottom end of the spine pointing at the right heel, the lower body levers are properly aligned to work in series to create immense power. The folding of the right arm and the windup of the forearms takes care of loading the upper levers. Simply reversing the sequence of movements that you made in the backswing keeps the mechanism in line and progressively increases club head speed. The system works like any other series of compound levers, each lever adds its motion and multiplies the power so long as the levers remain in line and the fulcrums maintain their relationship with the levers.
If the fulcrums move in relation to the levers the amount of multiplication generally suffers, as does the ability to strike the ball perfectly centered on the club face.
If you are losing power or not hitting the ball exactly in the center of the club face start looking for your error at the main fulcrum (the swing circle center), this is generally the culprit although once you are sure that it is stable and you still have problems at least you know which fulcrum you do not need to fix.
Since 95% of the problems in this type swing are caused by moving the swing circle center 95% of the possible errors will be eliminated simply by stabilizing this fulcrum.
