Shoulder Rotation

How should the shoulders rotate in comparison to the hips?

I have heard to think of the the hips rotating in a circular motion to where the shoulders should rotate more like a ferris wheel with the back shoulder replacing the front shoulder.

Or should they both rotate on the same circular plane?

Someone’s been reading Hitting Illustrated. :wink:

nope, just heard a couple of coaches talking about this the other night and they both thought they were right.
