Swing Efficiency

If you have talked with me over the last several months or seen me speak to groups of golfers you will have heard the words Swing Efficiency! 
This is a word that the Titleist Performance Institute utilizes to describe the optimal swing. Not the optimal swing period, but the optimal swing for an individual. 
The analogy that is used is the Golf Swing should be like a whip. Well actually the body should have four whips that build upon each other. 
Why a whip? Well would you rather get hit by the crack of a towel or by a limp towel? Which has more speed at contact??? The whip of course. 
In the golf swing your body should be a coordinated series of efficient movements, that rocket of each other. The peak or crack of the whip should hit and accelerate the next part of your body. It does not look like a series of individual movements, but a coordinated masterpiece. Yet if the movements are measured they occur in units! 
So where do these whips occur the first whip is the pelvis (belt buckle), the second is your torso, the third is your hands, and the fourth is the club head swinging through the ball. 
Okay so we have four whips now what?!?!? Well they need to occur one on top of the other in the order I described or else your swing will be inefficient and you body will be continuously correcting itself swing in and swing out! 
And of course if you are not cracking the whip you will not be efficient!
