The Gracies knew he was high level sifu Emin that is , that they told him that he has to wait in line!! But they offered Mike Tyson to fight in the UFC, right away because they knew he had no knowledge of martial arts!! But Mike was making more money in boxing than the UFC, so he turned the Gracies down!! Sifu Emin had alot of knowledge in fighting including the ground game & he knew it's weaknesses!! His high level attributes was the major threat!! In fact he wanted to challenge the Gracies with no RULES!!

38:36 to me.. the wall bag was really just something that gets you used to piercing the target. Basically stabbing our bottom 3 into the bag in an explosive motion. It’s just an extension of the elbow. Timed correctly, we can peel off a spike, remove it, that as another lands. But again. Focused, accurate, speed, power, intensity. Using the body to beef it. 😉🤟🤛👍😀

I believe, although not certain, that he and GM LT had had a disagreement about either what was to be taught at seminar or fees. Sifu Emin was upset and took it out on somebody. Sifu KS legs flew up in the air and he landed on his elbow hard. Felt bad for him.

Hi Sifu Alex, love the podcast! You guys are awesome! I have two questions that I'm hoping make it to the podcast to have them answered. First question is with all the Wing Chun out there no matter the lineage, you always seem to see just chain punches. You never really see Wing Chun guys throwing hooks, or upper cuts like the lifting punch in WT. Why is that? Also it seems to me like some Sifu's structure their students membership within their associations so as to keep them loyal for years and taking more than a decade to learn the entire system including the weapons. Honestly at times I felt like Leung Ting had a similar structure. Having trained in Kung Fu over 25 years I know the importance of solid basics and fundamentals but I've also seen some students with the ability to pick up quick. Has breaking away from the IWTA allowed you to have the freedom to have students excel at their own pace? Thank you! Much respect to you. You are one of the few instructors that I admire that teaches very well, in fine detail and is very astute and can explaining things clearly.

The Universal Truth is a bit more than that Sifu....There really is a best way to do it using all the technology and science availible. "Better is the Enemy of Good" Si-Geung KRK. But it is We the PEOPLE that get in the way... First the best way to do it biomechanically (including reaction time, the process of programing for use under stress, and for use in fighting not sports) and then second the best way to use this with each individual body. Third the truth with any human social engagement involves culture and religion,...and EGO, POLITICS, and LIES. You discribe the science half and touch on the cultural issue (reach underneath for backfist). But the Universal TRUTH is people do it. Most macho male egos won't accept theory from someone else, it is a "prove it to me" mentality...so Martial Arts constantly restarts itself with blunt force trama fueled with rage and slowly works it's way out of the ego trap for each of us individually. THe martial art itself is constatly restarting at the beginning. We COPY the big strong hero and then invent reasons it won't work for the small wristed 150 pounders...The hero worship and failed science is part of the Universal Truth too, a part we do not seem to be overcoming culturally very well. Thus, hundreds of styles and "best ways" to learn martial arts...all trying to find the same thing.

His student was one of the first to leave Hong Kong to teach and he was teaching it when he came over to England,Essex my Sifu said I cant remember his first name but his last name was Lou. Also on insta you put up a training video where you was talking about not having much space to train in certain places like where you were on the balcony of that cruise ship you put up a list of technices that we could do. So I screen shot the the page and use it as a work out for my training I've added to it but find a very good work out/ training tool so I would like to say thank you for that.
