A good pivot action is beneficial for hitting and swinging.

You need to learn how to direct the forces that runs out from your shoulder - down and out. On plane. Especially in hitting.

In hitting it's more right at the ball. In swinging it's more of a down first and then around. Anglede hinging vs dual horizontal.

I think you can do it by focussing on the pressure generated by your right hand. Aim straight for the inside aft of the ball with your right arm at all times.

You can't turn the shoulders blindly in either hitting or swinging. You have to tame and nurture it, so that creates an on-plane push and pull in your hands.
