We're talking about a Stroke that is two feet back and two feet through. Body Power? I don't think so!
I didn't mean the full fireworks e.g. spinning the flywheel and Right Shoulder Drive to Load PP#4, etc...
I meant using just a little Pivot to give that Left Arm a little mini blast off, as opposed to using your left arm muscles to move to left arm (ala Ben Doyle...that's a discussion for another day )
