Kajukenbo is an eclectic and versatile system that was born as a useful and credible tool for self-defense in modern times, it is not a martial art of sports or traditional profile and therefore its learning is suitable for all types of people whatever their condition and in which there is only one premise according to its creator Sijo Emperado. "Fight to train, train to fight, fight to win.... go for broke". The standard techniques, above all, have to serve as a model of application of different well-structured basic principles whose purpose is purely efficiency, sometimes even supported by the ability of creative improvisation. This is basically achieved by training different combinations of the same principles and avoiding their excessive mechanization. Every aggressor has a plan or a predetermined intentionality, so it is unquestionable to be extremely effective in the blocking and subsequent response by correctly using coordination and synchronization to break the opponent's initiative and position ourselves with advantage, and as Emperado said, suffocate him with quick and forceful bursts of blows in specific areas and move with dynamic and overwhelming transitions that prevent the aggressor's reaction.
