That's the point I was trying to make Pat. A "Flying kill" technique (as I posted in the "Tyre work of champions" video) is very effective. IMO jumping up and down on the spot without really striking is not. Again, my view is if I try and do a bunnyhop / kangeroo jump over a low attack I know for a certainty that my instructor will hit me three times before I land and then another 3 shortly after. Depending what mood he's in! The resulting ear-bashing would be mandatory of course LOL. So it's just not something I would want to try. People may do it and get away with it, fair enough. Many people don't look before they cross the road (well - in Asia it seems anyway!). Arnisador - thanks for answering that question. Phalanax - We were talking about raw beginners. I would suspect there's quite a few intermediates that could hit a Master of a different FMA system. Though that is also probably true in many different martial arts - not just FMA. Simon.
