Here's the "Swing Secret!" I believe the secret to consistency.

The golf swing is a "single axis rotation."  The body rotates on the base of the spine and the arms should follow both the rotation and "tilt" of the shoulders.  I'm finding tons of videos lately of golf pros being viewed from the back side.  They're catching on to the fact that you can view the base of your spine movement better from a back side view. 

If you can rotate with a minimum of lateral movement you can be more consistent.  Far less fat shots, catching it think AND most of all in my estimation...a better extension of the arms through impact which means NO MORE CHICKEN WING!

Take a look at this video.  Come see me to have your swing video taped form the back side.  I promise....no one will see your video without your permission.
