If you have studies Bruce Lee you would realize the incredible edge he had.
Ever see his one inch punch? The one that sent the Gold Medal winner in Judo ten feet back and tumbling over a chair!
He grew up beating the shit out of everyone on the streets too. Thats why he was shipped to the US.
He was also a master of harnessing the power of the person he was fighting.
He changed fighting on a mental and physical level!
