The reason the optimal golf swing is vertical and not rotary or lateral is because, as I’ve said before, you are using leverage and gravity to swing down into impact, and if your position remains laterally stable, you are golden with a modicum of practice.
I have taken a 5 iron swing and a Driver, to illustrate how purely you can strike the ball without jumping out of your shoes or breaking yourself in the gym.
