You hear both of these things, which is correct?
Actually they are both correct, but they are taught and implemented horribly…and horribly is not a strong enough pejorative.
The swing to right field is taught and implemented by disconnecting the arms and sending them out away from the body, while the club ends up under the plane on the back an downswing and either outside the target line or a flip at and after the ball.
Swinging left usually ends up as pulling the handle and yanking it left around the corner. In other words, a very steep shaft angle.
It’s no wonder why every thread on GolfWrx and other message boards in the poster asking how to get rid of snap hooks with driver and shanks with irons.
If you swing to right field with the arms, it will eventually end up in snap hooks because the path is too far from the inside.
Swinging left with the hands will eventually cause a battle with the shanks as you are steepening the shaft too much.
Swinging to right field and swinging left are nothing more than where a swing path keeps the club on the arc. From inside the target line coming into the ball (swinging to right field)…then back inside the target line after impact (swinging left).
The ball is the bottom and outermost point of the arc.
I am making a video today explaining all of this and what these ideas are actually supposed to mean.
I will post it tomorrow.
