A golf swing is no different than throwing a ball. Rotation and transfer of your weight from your back foot to your forward foot is what make the ball go. And it works for the golf swing too.
Within this video I published 3 years ago, I use an impact bag as a weighted ball, that I “throw” to recreate the rotation of a golf swing. You don’t need to hit golf balls to learn to rotate. But using resistance to learn this movement can certainly assist with ingraining rotation in your golf swing.
