Here is perfect video dealing with putting your body behind a punch.
Now take into account WC body mechanics are different and shorter. They are made to fight closer and use more speed than power of a boxer.
But if your interested in training to add this sorta of power to your WC you have to mix it up with boxing body mechanics. In other words you have to switch from one form of fighting to another.
But its cool to understand the philopshy behind why this techniques works. I don't think the guy who is doing the punches has the knowledge you have. But he has the experience from fighting and the conditioning from building up the power from
-push ups
-weight lifting
-hitting a punching bag
An what ever else I didnt mention.
Instead of telling us about this theory and that theory why not talk about how one develops it. Dont go mystical. Simply speak about the training that it takes phyiscal training that is to develop power like...
In your Mythical Chi video of the japanese guy making his energy pass through three guys. Whats the purpose of that skill? Why would you use that in a fight? Also how do you train to develop it? Dont say its chi. Because chi has to be trained by chi kung,strechting, hitting objects hard. To be able to manifest chi you must do both Soft or Yin exercises as well as Hard or Yang exercises. If you simply practice forms in the air with no Yang your chi wont be strong. If all you is stretch an never punch or kick anything than you will be flexible but will lack power(chi) to actually allow the chi to flow through your meridans to distrupt your opponents meridens and damage his chi flow.
A guy who can punch a 200lbs and make it move has more chi in punching that a guy who only does SIL LIM TAO
Oh by the way the guys doing Muay Thai delievering the knock outs. I betcha your long winded discussion on momemtum would go way over his head. He would have no idea what you mean! nor do i...reason being because it doesn't tell me how to develop it. I dont really care about how chi has the ability to knock someone out. Show me how to develop it properply and teach me how to apply against someone fighting me back.
