Okay so im 16 now and ive decided i need to do something. Right now im torn between boxing and mma, im 6'1 203 pounds and i got a muscular build not really defined but im very powerfull for my age and weight. Im not too fast though and id have to learn how to grapple if i were to do mma. And for amatuer boxing is it hard to get a k.o? because that would probably be my main way of winning and also the way id want to win.
