Mechanics of Instinct
The process is pure and simple. Remove all non-instinctive movement from your game. This allows the cerebellum, which controls all human movement, to use it's full capacity for precision and finesse. This is the body-brain synergy that produces trust in thyself and the peak performance that follows.

True, there is not one swing for everybody. But there is one and only one swing for each individual; it is the swing that makes the body feel safe enough to focus on precision and finesse.
