For a number of years, I sought to develop my own hybrid art system due to the fact that I am a lifelong veteran of cerebral palsy, and walked on Canadian crutches. Commonly called forearm crutches, they. Are very much like a tonfa or pr24 baton. I repeatedly broke many a pair of the weaker aluminum versions on heavy bag workouts and redesigned them and built a pair from stainless pipe that weigh roughly 2.5 times each what an aluminum crutch does. Needless to say they are coconut crackers! Now that I am older, I am considering iron palm training, but I wonder...is there sound martial science to support what is seen on YouTube and other venues, or am I barking up the wrong tree? I know for a fact that Dim Mak techniques are effective if properly applied, as the art of medicinal acupuncture is closely associated with the roots of Dim Mak. From the best I can tell, iron palm and dim mak are often mistaken, intertwined and misrepresented as well, but I digress. Any thoughts on how I could best approach this training? Thanks!
