You guys are making it too complex for fab.
The theory is that jing is stored in the tendons… eventually (it works its way in there) unless you “squeeze” it or “spiral” or circulate it (refer to various methods too numerous to mention here).
The the releasing of jing is based on usage of tendons, not the muscles they attach to. The metafor I like to use is one of the image of a baloon animal:
Inside the legs you have a small amount of water. Water is another way of saying ‘internal jing’ anyways. Now if you pick the dog up and move him like how you would walk. Ie: Lifting and seting him down, the water really doesnt move in any spectacular way.
Now if you push down on his backside and let go quickly, what happens? The water shoots up. Thus the theorys that say “go down before you go up” or “go left before you go right”.
Say in tai chi. Instead of pushing your arm out in a regular snap punch you do a cloud hand movement to wind up then you punch…
The binding, drawing and springing action released more “water” than pushing or throwing… Does that make sense?
I fear this is too overcomplex and based on cultural schisims. Big strong people from the north are barbarians. Chinese are superior, civilised, small people who dont need muscle or horses.
An 80 year old chinese man cant beat me at armwrestling or tug of war. There are different types of combat/war. Those latter are classifyed as “pugnatious”.
Crushing my hand with the tiger claw or using the poison finger are overkill for that kind of thing and a overcompensation for lack of, perhaps, sportsmanship, honor (for the rules).
The best horse breakers i’ve known were all under 5’ 7". Not something most people regardless of gender or strength look forward to.
The main problem now is if you have internal jing, how to train it, how to store it and how to prove you have it and if the time invested in doing so was/is worth it?
