...to do with martial arts? There was this video on youtube I watched a few months back that was more than one part, like maybe 45 minutes total. It had different martial arts it was talking about, like ones from Okinawa and Korea and then one that a man invented form the US. He has trained in some other style and decided to invent his own. and it had to do with getting punched a lot and was about a lady trying to get her black belt in it. I just need help trying to look it up.
