I have indicated before that it is dangerous to be obsessed with “power generation” in your martial art; there is so much more, particularly if your approach is oriented towards civilian defence . You don’t want to get hit, for starters. To do that you need not only evasion but “blocking” (deflection) .

The equation for momentum is simple: p = m x v If you want to hit harder, you have to move your mass faster. There are glosses on that (as I’ve detailed in my articles “ Kime:
