Actually he brought western boxing and fencing techiques into CMA. He pioneered cross training and broken the taboo that tradition in MA must be upheld. He brought scientific conditioning into MA . I think he also cracked open the mystic nature of MA and presented it as a scientfic training.
He was not the only MArtist to provide a scientific framework for MA. Gen Choi , founder of ITF TaeKwonDo, created a unified and regulated curriculum for TKD, based on his Theory of Power. Ed Parker Sr, established American Kempo and advanced the principles of motion as the foundation for Advanced kempo. Imi Sde-Orr refined unarmed defence against armed attack, Krav Maga. It is simple, efficient and effective. It is so simple one would wonder,"Is that all it takes?" . Actually, no. It takes some conditioning. If you kick and punch like Oprah, then you are out of luck. lol
