I am just dumbfounded when I tell people with vertical shoulder turns that have paths too far in to out think leveling out to move the path left is over the top.
If you have some tilt away from the target and don’t move your head laterally toward the target in transition, you shoulder turn can’t take you OTT….period.
The issue is when beginners and hacks rotate over the top, the cure is to swing to right field, not to fix the body angles.
So you steadily evolve from an over the top slice, to an under plane hook and block.
It’s this simple. Shoulders move at a 90* angle to spine on downswing, add some spine tilt away from the target that’s created by the slight shift into the left side while head doesn’t move target ward….shallow, from the inside and not stuck.
As a side note, my shoulder is getting better.
