I visited my friend's karate dojo for sparring class with some of their black belts. I am not wearing any hand protection because I made a rule for myself that I would not do any punching, only trying to defend and control the opponent. My opponents have various levels of training experience ranging from 8 to 14 years, and one of them also has experience with BJJ. I got hit quite a few times, and my opponents' hand protection made wrist techniques pretty much impossible to execute, but I believe these highlights show some of the effective potential of Aikido principles against trained, resisting opponents. This video is NOT intended to assert that Aikido is inherently better than karate or any other art, only that it deserves recognition as a legitimate martial art and viable method of self-defense. Thanks to my fellow martial artists for their hospitality, spirit, and sincere camaraderie.
