I think there are the viable ways and the "mentioned but not known if viable" ways.
For the former it is nothing more than developing your proprioception and perception, but being able to feel and know some things doesn't automatically means having conscious control over them.You can try to learn more about human anatomy, physiology, acupuncture and other disciplines that are all about learning about how the body works, but again, knowing the "how" doesn't mean that you will suddenly be able to know how to control it all.
For the latter, there are different methods/systems that claim to allow a person to be able to achieve complete body control, like doing yoga or certain types of meditation, but realistically I don't know how much control people do end up getting over their bodies.The best examples we have so far are people like shaolin monks, gurus, and specific individuals like the "Iceman" guy(Win Hof).They learned to have a better control over their bodies, but that doesn't mean that they can do anything they want(like making the healing process go faster than normal, or giving themselves more strength without working out).
Why you seek that, if you don't mind my curiosity?
