Relax lower back, keep a gentle upper-body arch

On the back side, the coach says not to worry about sticking your butt out and to relax it, keeping just a gentle curve in the upper body. He explains this is a natural arch because the lower back isn't designed to turn and turning it can cause pain, while a natural arch in the upper back helps you stay connected through the swing, leading to purer shots and cleaner contact.
