If you've ever wondered why female arm wrestling hasn't taken off as a mainstream sport, this may explain why.

In this gruesome -- not just gruesome, but GRUESOME -- video, a woman who's already nursing one broken arm inadvertently finds herself going for a matching set during an arm wrestling match.

The sound of the arm fracturing at the 22-second mark will make you wonder why you even watched the video in the first place. It's that awful and maybe a clear sign she should take up another sport.

You've been warned.
