Frank William Dux (born 1956) is a martial artist and fight choreographer. Dux established his own school of ninjutsu in 1975, called “Dux Ryu Ninjutsu”. An article about his exploits, which appeared in Black Belt in 1980, was the eventual inspiration for the 1988 film Bloodsport starring Jean-Claude Van Damme. https://officialfrankdux.com/
This is a prime example of Martial Arts Envy surrounding one of the icons who started it all, for all the rest of the M.M.A. doing the very same things. Just like the former President of the United States, everybody wants to TAG TRUMP for a public relations ride of any kind. In the first few paragraphs of this scribe admits his title is NOT TRUE is tagging along with what ever Frank Dux is affiliated with. This is actually an old-school method of copy-catting the big boys in Hollywood and elsewhere.
