I've knocked down a few mayates with hooks to the body.
If the guy is prepared take a hit to the stomach it won't really hurt. He'll tense his stomach muscles to absorb the blow. If the guy is winded and doesn't really see the blow coming or for some reason not tensing his stomach muscles... it can buckle him.
Punches to the liver, spleen, and kidney's in any kind of environment hurt.
The head is small and in a street fight I've seen people move all the time , I'm sure if I ever get in a street fight I'll miss 90 percent of the punches to the head . So is it a good idea to try and punch in the body? Like punches to the liver , to the ribs , the abs, the chest , the kidney area , will it stop someone in a street fight?
