I do this as well and thought I was the only one until I stumbled on this forum. To ask how I do it is a bit like trying to describe the color red to someone who can’t see color, but here goes. Imagine your brain to muscle connection is a tightly wound ball of rubber bands. The tighter that ball the more instantaneous control you have over your muscles. Now imagine you can do something that starts to unwind that ball before it snaps tight again. You do this thing, it starts to unwind, and you can feel something like tingling electricity in your muscles as the mind-muscle connection is becoming more loose. You can only hold it for a few seconds because it wants to snap back to being tightly wound. That’s my metaphorical explanation for the feeling but the physiology of it has me perplexed, and I’m a spine researcher. Whatever I’m doing to cause this starts in my core and then radiates to my extremities. It’s a loosening of this metaphorical ball of rubber bands but shouldn’t be confused with relaxation. It’s an immediate event, controllable at will, sort of like flexing a muscle. It’s such a strange sensation that I feel it has some kind of importance. Charging the immune system maybe, just speculation but I do it anytime I feel like I’m getting a cold. I always feel energized afterwards. Unfortunately, whatever we are doing is either rare enough that it hasn’t been studied, or is just too subjection to be explained adequately enough for science to investigate.
