Obviously, Muay Thai, boxing and American kickboxing predominate in MAM striking bases because there are sufficient numbers of trainers and coaches teaching them in a full contact and properly intense manner and have guys swinging at something besides air molecules. And that Muay Thai,kickboxing and boxing often have the upper echelons of athletes in combat sports due to the ungodly amount of money they can make relative to combat sports, and for boxing relative to pretty much any sport for the top few. And so when martial arts like TKD, Goju Ryu Karate,Hapkido, Krav Maga, Kyokushin, Kenpo, Kajunkenbo, Wing Chun and Shanshou are trained in passive and/or McDojo and/or "artistic" styles, they are not gonna work much at all. But why do we presume that these arts are useless relative to boxing or Muay Thai, in MMA or in a self defense or parking lot fight scenario, even when they are taught by trainers and coaches who have their fighters swinging at pads and opponents going full speed and training at the same intensity as Muay Thai guys or boxers? I mean, are you going to go to a Japanese training center and tell fighters Koykushin does not work, go to Israeli commandos and tell them Krav Maga is a joke, hit up Hong Kong and tell a group of street fighters there Wing Chun is just third rate kickboxing or to Northern China and tell that to fighters in a Shanshou studio? Oh I'm sure some guys here say they would but really? So where does that idea come from?
