Judo Tom said:the easiest way for me to do it is with a throw onto concrete.. but its my technique that will knock him out not power..
i think the placement of a punch is what leads to a knockout and the power behind just increases the area where you can hit and get a knockout
also some people have a very very high tolerance for either getting knocked out or NOT getting knocked out. I dont know if its how there brain is wired or maybe their head is built different..
what area of the head is best to hit if going for a knockout?
I would say temple followed closely by jaw
but when someone lands on concreate from a throwyou cannot say there is no power there
that is quite an impact!
