Mr. Cunningham would continue to develop his martial arts skills as he grew older by training with karate and tae kwon do students and black belts whenever he could and would seriously continue to pursue the Western Martial Art of Boxing with what would become an almost consuming passion. He had a great appreciation for and became a serious student of the history, art and style of Boxing. He greatly enjoyed being able to express himself in this "art" and honed his skills to eventually earn the nickname, Buck "The Cobra" Cunningham, and achieve the impressive accomplishment of winning Championship Boxing Titles in two different weight divisions. Mr. Cunningham compiled a very impressive 57-2 record in sanctioned Boxing matches (and many still believe that he only lost in one of those :-). Importantly, he also fought countless rounds in preparation for these matches (and also just because he liked it) with bigger boxers, karate stylists, tae kwon do practitioners, wrestlers and self-described "street-fighters"), many of whom left with a real appreciation for how he was able to adapt his "style" to make himself effective against their "style". These would all prove to be valuable and important steps in the long evolution of the AFFKbJ System. Mr. Cunningham's continued personal growth, his thirst for knowledge and his passion for the study of fighting systems would lead him to eventual submersion into and exploration of many different "traditional" martial arts styles. His achievement of advanced Black Belt rank in numerous of these "styles" and his continual, thoughtful and purposeful examination, assessment and evaluation of the strengths and weaknesses of different fighting systems and methods of teaching, which began in the early 1960's, eventually led to the formalization of his own creative thoughts and energies and ultimately to his founding of the revolutionary American Freedom Form Kenbo-Jitsu (AFFKbJ) Hybrid Mixed Martial Arts System.
