One of the most common swing characteristics
that lead to lower back pain in golf amateurs is the sway. The sway is an inability to rotate correctly. So instead of rotating with the takeaway on
this axis, the hip is elevating and is shifting laterally. And this locks the body so it can t rotate
anymore. But instead, you just can do this. And this is called the reverse spine angle. The reverse spine angle is the number one
reason for lower back pain in golf.
