Use elbow on the backswing?
 

I've got so many thoughts running thru my head after just 1 thread. Please clear the fog a little. I've seen where some say the backswing is a result of the right elbow bending. Is this true for all swing types? (swingers/hitters). Currently my backswing is a bit of a heave over the right shoulder. This causes the right elbow to bend beyond the common benchmark of 90*. My backswing seems to stop once my arms have run out of room to go back.

Extensor Action
 

The bent right arm is trying to straighten, but the left arm won't let it. Use extensor action to keep everything in-line.

It might have been me because i tell people all the time to bend the right arm.

What i mean is that the bending action of the right arm (at the elbow) is what RAISES and LOWERS the arms (both). Obviously it isn't the entire backswing and more movements involved.

I just see some people trying to use their hands to "lift" the club somewhere or "raise" the left arm and results aren't good. Gotta bend that right elbow.

But should the folding right arm be the motivating force of the backswing, or is it shoulder/arm/hand driven?
