Accurate as well. It’s a simple way to move.
You stay balanced and steady. Add the leveraged arm motions and you have a swing that is fast, long, and straight.
In fact the biomechanics and physics are backed by science. It’s the most efficient way to swing.
The pro swing is on 2 opposing axis and can lead to injury. This method is on a vertical axis and is friendly. Yet really powerful.
Try it! You’ll be glad you did.
