Teaching McKay Body Movement using Physics

[lady-ceylonna.livejournal.com]

I'm looking for stories that have someone using physics (or scientific principles) to teach McKay self defense or just general body movement  or awareness.  For instance, in yoga stacking the joints and having certain body parts parallel or perpendicular can take a pose from impossible (when done incorrectly) to doable due to the physics of the body. Similarly some martial arts focus on using an opponent's momentum against them.

I've seen some stories that use his knowledge of physics in firearms instruction, but not for hand to hand.  I'm looking for stories incorporating the physics of the body.

Thanks!
