I think we all know the basic elbow block as shown in this video:
But how effective is this technique? Most of the time the blocking person brings his arm at the side of his head and makes contact with his skull. I´ve tried this technique with a friend of mine and we noticed, that the powertransmission was still to high. After various variations of the technique we´ve noticed, that it is way more effective to bring only your hand to the head and the ellbow between his attacking hand and the head (without contact between forearm and head). So what do you think? I know that it is hard to block a punch but I like the idea of the elbow block as a guard between my hand an my oponent´s free hand while I secure his other one, in order to prevent me from a direct strike. But what was wrong with our first try? The technique is used in various martial arts and MMA, so it should be effective. What do you think about it?
