Do you own your legs?

Readers can comment on this provocative idea:
George Xu claims to be the source behind Chi Running. One of the things he said is that most people let their legs carry their bodies, they don't use their bodies to carry their legs. By this I understand him to mean that most people lack both integration between their legs and their torso, and they also lack a kind of mind or embodiment.

This integration of the legs and torso, once gained, can be measured as a smaller, more efficient range of motion.  Xu refers to this type of embodiment as the predator mind. It is a kind of fearless self-possession. It is a predatory way of seeing and moving.  It is relaxed yet ready to pounce. It is drawn in toward the center but not closed, not  contracted.
