Yes, seriously , but anyway it is hard to reply when some one bans you till end of month. Here is a small description of internal external, do not know if it is what you want, but read it and see. Internal" isn't a fighting method in itself, it's a methodology for power generation and the basis for (for lack of a Chinese or English term) "aiki" -- a specific kind of internal structuring that allows you to control the body of another -- instantly upon contact. If your opponent attacks you, you can receive, absorb and neutralize his power and then return it to him, augmented with your own added power. You can either bounce him off, stuff him downward, suck him in and seal to him and smother him with your own "sticky" body. Controlling his center, even briefly, buys you enough time to do whatever you need to subdue him -- throw him or take him down, choke him, or whatever other sequence of attack avails itself. So, if he throws a hook punch, you can use that hook punch. In fact, you would WANT him to try to punch, kick or grab you because any contact he makes with you provides the pathway for you to control his center. External method relies on torqueing the hip, pivoting on the foot, and using other "outwardly generated" power sources to drive technique. By contrast, Internal method manipulates fascia, tendons, breath, joint connections and other "inside" things to create "inwardly generated" power. It allows you to hit and kick without chambering or torqueing the hip or pivoting on the foot. It also allows you to "have no center" so no one can find where your body mass is focused. This makes it extraordinarily difficult for a non-internally trained person to sweep, throw or take down someone who has good internal method.
