That’s what we hope to achieve…buuuuuuuut a few things have to happen to get us there.
1. You can’t just have any old backswing. Has to be competent, not to be confused with perfect.
2. You can’t just fire the lower body in either a slide or hip spin and have passive arms, because, “The swing works from the ground up and you just need to fire the lower body.”
What are the answers to 1 and 2 as to how?
The long answer is called golf instruction.
The short answer is you need a grip that allows your body to be in decent position at address, at the top and that allows the club face to not be too open to the arc when the shaft is parallel to the ground coming into impact (P6).
You need a backswing that makes it the easiest possible for you personally to link your arms up in transition.
You need a transition intent that allows your arms to link up by the time the left arm is parallel to the ground coming into impact (P5). For some it will be a lower body intent that pulls the arms into the body properly so the pivot can rotate the club into impact…or an upper body intent that gets the arms in position so the pivot can rotate the club into impact.
Don’t let anyone tell you one is right and one is not. Everyone is different.
