A good way to start developing proprioception is by doing bodyweight exercises, because you end up learning more about which muscles you are feeling and what they are supposed to do, expanding your perception of each and every movement you do. Calisthenics works with either very precise-requiring a fine control of strenght-or fast paced exercises, both forcing you to get better at coordination since a bad call at the wrong time can result in injuries. Sprinting develops power-explosive strenght-and control of said power. Most martial arts help with fast eye to hand coordination and with setting your personal space of action. The P.S.C. is something I came up with, but it should hardly be considered an original concept. Basically you set a certain radius around your body as the area where your attention and awareness will be high, and anything or anyone that enters this zone should be treated as possible threat.This way you will not only learn to focus on what is happening near you but you will also be already prepared if something happens. At the beginning it will be tiring but with time it will become second nature and you won't feel as strained. Which kind of exercises the people of this community practices?Do you think that they contribute something to your psionic training?
