This is a curious short film. Its subject is clearly a proponent of the “more is better” and “more crazy is more better” schools of training. I by no means recommend spending several years attempting to hang from a tree as a way of improving your harai goshi throw, indeed, I recommend against it, on the basis that harai goshi doesn’t involve prolonged isometric holding of the position in question, and is easier if you haven’t destroyed your knees and elbows. But this is sort of interesting anyway.
Also, John Wang seems to have invented the “right-click” mouse button. Who knew?
