Thanks for that video, MO. I don't know where it went!!!
I had an answer all written out for you
No, I haven't. Very, very, interesting.
My gf is a Muay Thai fighter and has moved into Krav Maga and I can't get close to the level of ability she shows there. With my interest in body mechanics to the fore, I went to t'ai chi originally as explained above.
My teacher had trained under Dan Inosanto and that little, tiny, guy could do stuff that would blow your mind. One time, a lesson had ended and we were winding down - myself, brother and brother-in-law as was at the time. We were fascinated by the concept of the one-inch-punch and Michael, my B-in-L, figured he'd be willing to be the subject.
So, we crammed a couple of phone-books down his t-shirt, padded him up as best we could (hey, it was all hype, right?).
Our teacher got us to move a big, chunky, armchair behind our guinea pig - and again, we figured he was just playing along and giving us a laugh.
They got set up.
Well, watch Bruce Lee do this online and see what happened next...
He literally knocked Michael flying off his feet and back into the chair, which like a cartoon, slid back a couple of inches across the floor.
Michael was rockin! We got him up and he was laughing so hard. We asked him how it was and we were like ''you were playing along, right?'' and he says, ''nooooo...that really
He had a fist-sized bruise on his chest the next day, lol.
Our teacher never did that again and he did tell us that he had controlled the explosiveness and in no way did he go anywhere near full speed.
Oh and by the way, Michael was a BIG guy. All muscle then from working on engine's all his adult life till then. Our guy was a good ten inches shorter than him and half his weight.
An incredible guy. The techniques I learned from him...wow...and we only scratched the surface before circumstances meant we had to stop our lessons.
