Even if you take the THREE use cases at face value (which I don't) that is not a large enough sample size to be legitimate. Yet I'm the illiterate one here.
Nothing you or anyone else (including the video) has said have addressed the 'no live contact' problem. You can't learn anything without practice and experience. You can't learn the piano by not playing the piano. You can't learn to paint without actually painting. You can't be a communist without study and practice. You can't fight people without fighting people. Do you understand? MA is not an exception to this rule! Practicing on a log like the guy in the video is not a live opponent. Not sure if you're aware of this but logs can't fight back.
Any dumbass can use weapons/dick kicks. There is nothing novel at all about this, it isn't the cheat code you think it is. A real martial artist isn't just going to throw a knife away lol. I'd also bet the guy who kicks REAL opponents (aka not logs) for a living will be better at dick kicks.
He never said anything about cardio, he said nothing about movement, and noise is irrelevant. Did you watch the video?
Now all I want to do is promote REAL self defense for comrades, because I don't want them to get their ass beat. You and a couple others seem pretty upset about that and decided to take personal shots at me instead of rebutting my critiques. Sounds like a personal issue you should investigate.
Really the only two people who fall for this crap are the most gullible people on the planet who are looking for a quick solution that doesn't exist, and actual children. I've said what's needed to be said on the subject. I don't have time to argue with fools and children.
