Thus the metaphor used in Daoism and Chinese medicine is that the muscles are the troops, soldiers. They need to be well trained and well cared for.
If the muscles are making decisions, you will have mob rule. Alternately, the internal organs can function as a government, the heart/mind is the Emperor, the lungs are the chief ministers, the spleen is in charge of ordering, logistics, "ways & means", and the liver is the general, in charge of delivering blood to the troops and mustering them to action.
Well trained troops certainly can take some personal initiative. If it is truly in support of the larger cause, personal initiative can make or break a campaign, still the troops are rarely in a position to make good independent decisions so most of the time it is imperative that they simply follow orders.
For an army to function well, every stage of leadership must be clearly delegated and the chain of command exact.
Our body has things called proprioceptors which tell the brain where we are in space, where we are moving, and how fast. Most people's armies are in disarray because their proproceptors --scouts, spies, and communications networks-- are poorly trained. I don't know for sure, but my experience tells me that large numbers of proprioceptors live in the ligaments.
The muscles can move without consulting the ligaments but it is clumsy, the ligaments should lead--calling the troops, the muscles, to order. Once that mechanism is in place and scenarios have been set up and drilled, then the troops can be commanded.
