I believe golf swing is no longer subjective art, but it became a quantifiable science which can be controlled and measured. It is based on fundamentals from physics, bio-mechanics, and kinetics. Lean to create speed and power and to transfer momentum from body to arms and club. With this method applied you will learn much faster than other methods like teaching a style.
I do 3-D bio-mechanical analysis (K-vest) and multi-angle swing analysis (JC Video), club fitting.
