Ah jeez, I was hoping for more about the alignment of structure in one's body to apply the greatest precisely-directed force (etc.), but it just focuses on the gimmicky stuff I find the absolute least interesting about martial arts (the showy "breaking objects" stuff)... The post should be titled "why our hands can break wood and bricks but not bones". The physics of karate are pretty fascinating, I would love to read more material that discusses the subtle differences of positioning, momentum/inertia, "spring action"/compression, all that kind of stuff.
