Perhaps, people don't understand twisting. Could be because all we get hear from the medical field is how we should avoid "twisting" movements.

As Mr. Schmitz put it, "Twisting is rotating without using your hips." While excess strain on your lower back is never an ingredient for pleasure pie, training your body to perform proper 'functional' movements with correct form can do wonders.

In short... rotation with hips=good and twisting w/o hips=not good.

What is that behind you??? Don't forget to rotate those hips.
