One of the key principles to help you understand how the golf swing works is knowing where the center of mass is on a golf club. The golf club’s center mass is somewhere on the shaft – that doesn’t matter. The key piece is the club is trying to rotate around that point in space, and we’re applying force to a different point (our grip).
Once you can wrap your head around the fact that the club moves around your body at the center of mass, you’ll begin to understand the complete workings of force up from the ground, through your body and into the golf club and clubhead.
