Want to know the easiest way to make a
full backswing?  Forget rotating or turning any of that
talk. Shifting and turning.  There is a much
easier way. Think about starting a lawnmower.  Grabbing the handle
and pull. Think about your backswing  as a pulling motion. Pulling that right
shoulder  back in this motion here and no matter
what sort of flexibility  you've got you'll be able to make a full
shoulder turn. Think  pull back. Grab a club.
Set up to one and just think pull that  right shoulder back
and you can make an easy  full backswing every time. Hit the ball
further and more consistently.
