David Lee, developer of the GRAVITY GOLF® teaching system, has been conducting research on putting skills for more than fifteen years.
We've been told for ages that individuals who possess great putting technique like Bobby Locke, Ben Crenshaw, Raymond Floyd, Lee Trevino, Phil Mickelson and others, are "born" with the skills and a "God given touch." This is absolute nonsense! These individuals have unknowingly stumbled across the ability to deliver power in the putting stroke through "counterfall" and pivotal rotation. There is a "trick" to what they are doing. The technique is extremely subtle and would be almost impossible to learn unless you know what makes it work. The individuals mentioned have all had the technique of "physics perfect" putting, but have not possessed the communicative skills to teach it to others. Once you know how the technique works, it becomes very simple to develop and will never leave you. Anyone can learn to putt like Ben Crenshaw or the great Bobby Locke, once they know the "recipe" and how to teach it to themselves. If you don't believe me, I'll be more than happy to prove it to you. - David Lee
Along with his discoveries on putting techniques, David Lee began to realize that in the last fifty years almost all putters have been designed with very upright lies and with very little loft. Putters designed in this fashion prompt the player to putt back and forth on the intended "flight line" of the putt instead of on an "arc." When a player putts straight back and straight through on the line, only the mass of his arms and putter go against the ball. Comparitively, when a player putts on the arc, with proper technique, almost the entire body mass moves against the ball and the flight-line is tangent to the arc. The difference in contact is like hitting a tree with an axe as opposed to a hatchet. A golf ball at "rest" has powers of resistance to being set into motion. Because more mass is released against the ball in the arc stroke, the hands are left free to "feel" and are not required to generate power. The more you separate power and touch, the greater your touch will be. The ball covers the distance to the hole with only a fraction of the effort, and energy is not turned back into the body due to applied arm force (which causes path-change and missed putts).
