Yeah Karate & kickboxing was his main thing. PKA or something like that.
He fought some Thai's overseas at one point and got his legs raped. < He still disputes losing i think. I also think he beat a few later once he learned how to deal with low kicks.
At one point he was going around saying he was undefeated when there was footage of him getting whupped by thais.
Still a bad @ss and a legend. I had one of his books growing up and i was a fan along with Bruce Lee, Gene Lebell, the Gracies, other legendary kickboxers & boxers.
Yeah I remember reading some controversy about his "undefeated" claims. Regardless, I wouldn't wanna be in a ring or a cage with him
