Instead of just "a pokemon that knows martial arts of sorts or is buff" its the energy of life in a body.
A lot of martial arts talk about using chi for their moves, and explains why they can break rock, ice, etc. as well focus and tone the body. I just see it as the excess energy from the good forms and flow from martial arts, in this case.
Also explains stuff like Aura Sphere and Focus Blast.
I actually went and became a massive faggot and did this chart.
