yeah, i don't pack a lot of raw power, not that a punch from won't do any damage, but i'm not a big guy with niether large muscles or lots of bodyfat so you won't see me benching 150. but i can move fast, and that speed and momentum makes up for my lack of strength. and no matter big you are, fast, solid strikes to your neck, throat, diaphragm, and groin is still going to hurt.
