Re: It's (not?) all in the hips
Interesting thing. In aikido we do most of the techniques with our upper body and are constantly told (at least I am) to use or legs to generate the power. In capoeira, most of the techniques are kicks and we're told to use our arms and shoulders to generate the power. I suspect it's not about using one over the other, but really about using the whole body in concert. It's just we tend to get hung up on the business end (arms in aikido, legs in capoeira) and let the other half lag. The hips.... well, they're in the middle and so get used both ways.
