We've all heard how Helio took the JJ he learned from Maeda and adapted it for his small, weak frame, thus giving birth to BJJ/GJJ. But what WERE the big adaptations? I've never studied anything but BJJ, but from what I understand, most BJJ techniques are the same as techniques from JJJ, Judo, etc. I own the "Gracie JiuJitsu Master Text" that Helio wrote recently, and I'm curious to find out what moves are so "revolutionary" from Helio. So the simple question is: What really were the revolutionary techincal adaptations that Helio came up with, that make GJJ so different from JJJ?
