I watched it too, and it was awful. She held it for a few seconds with her elbow just slightly bent backwards, and I was cringing into my sofa. When she lost control of it and it went totally wrong, ugh. It looked scary as hell. Terribly painful too, I'm sure.

Edit: Perhaps I should have looked at the link first. The injury I saw was the <106 lb women competition, but it was similar. I didn't know one of the men did it, too. His looks worse. Ouch!
