This video is not Krav Maga, but I found it very inspirational. Ross Enamait had it posted on his website, but I’m not sure who the original creator of the video was.

Shun Fujimoto was a member of the 1976 Japanese Olympic Team and ended up giving a phenomenal performance even though he had a broken kneecap. I’m not advocating pushing through an injury under most circumstances. Certainly Mr. Fujimoto ended up damaging his leg more so by continuing in the event, but there are times that you have to press on regardless of the circumstances. His story is a prime example of the heart that all of us need to have. One of the true tests of a person is what it takes to stop them.
