One of my many tasks as assistant HS coach is to actually teach girls how to throw overhand properly, how to whip with their arms and bodies. It's not as easy as it sounds. Most girls want to push the ball right past their ear. I teach a three quarter whip and I teach it sequentially just as I teach throwing underhand sequentially. That being said I needed some slow motion video of how men pitch, I need to convey to the girls that our hand belongs outside the elbow at roughly a forty five degree angle as we throw. So I searched for a video to demonstrate this. What I've actually found is a nice video of Tim Lincecum pitching using IR. Enjoy.
