INJURIOUS POSITIONS

[lagster]

What are some of your views concerning some of the positions, motions, or actions that tend to cause trauma or pain to the BACKS of golfers, during the golf swing(stroke).

I often hear about certain positions, swing techniques, etc. that can be harmful, but seldom hear detailed explanations on this.

The old "REVERSE C" used to be one thing that got criticized.

I'm looking for a little more detail.

p.s.-- an elbow, shoulder, neck, wrist, and knee category might be good also
