Im a big fan of breaking down fight tape,you allways learn something,even if what your learning is "Dont do that"

First go and watch the tape on the first two Holyfield/Bowe fights
Bowe is clearly the more powerful fighter,and usually gets off with the same speed.But he cant take him out,and other then the uppercut,he rarely hurts him.Its enough to drive you distraction really,but then look at his hips.Its like the bottom half of his body isnt particularly interested in what the upper half is about.
Then go and watch just about any Ann Wolfe fight,and notice how her entire body explodes in to her power shots
