Bethany Hamilton lost her left arm in one of surfing's most famous-ever shark attacks. Which makes the fact that she's one of the world's best gal surfers even more impressive. Now, before you watch this, clear your mind of the over-saturation of air reverses that has rushed through surf media like a tidal bore over the last three years. Because what this is, is a woman with one arm stomping a really critical and tweaked out frontside air reverse over an Indonesian reef. That's about as badass as it gets. Don't stop the music, Beth.

This cheeky back-of-the-cam footage is a leak from an upcoming documentary about Beth. Based on this, we're rather thrilled to see it.
