This makes too much sense. lol
"The club-focused instruction long advocated by de la Torre and Ernest Jones prior to him has now been validated by new research performed by Dr. Gabriele Wulf at the University of Las Vegas and by Dr. Bob Christina at the University of North Carolina.
In their studies players of all skill levels improved faster when given club-focused instruction."It has been recognized that the golf club is a tool and humans are remarkable in their use of tools (hammer, scissors, scalpel, knife, tooth brush, etc.). With none of these, or any other tools, does a person attend to how the body is used. The body action is a subconscious physical response to the user's conscious mental intention."[7]"
