Approximate the left arm by looping a 4-foot cord around your left shoulder and stretching it with your right hand. Swing the stretched cord to the Top -- right shoulder high and On Plane -- with your right arm.
That is the Mechanic.
And that is its Feel.
I wrote a post recently for DrewitGolf with an idea for a TV teaser spot on exactly this mechanic. I'll find that post and link it here. Meanwhile, if anybody beats me to the punch . . . Thanks!
Was that post for DrewitGolf or that other great New Englander BBax? I thought the suggest demonstration you gave BBax was excellent and would love to see it in the video Gallery. It sounded both informative and entertaining.
