I have an extremely flexible shoulder. That spot on your back that you can't scratch doesn't exist for me. In fact, when I did a flexibility test, my doctor marveled at the fact that I could clap my arms together behind my back, and pull them together so my palms were past my opposite hands' wrists. Now, I did not come here brag about my flexibility. How do I take advantage of my shoulder? What shots can I enhance with my shoulder?
