Hmmn. I'm unsatisfied with my last reply to you, but I'm unsure of how to explain myself better. I can't tell if it sounds like I'm agreeing or disagreeing with you and I'm definitely not disagreeing with you.
OS seems like a double-edged sword. On one hand, the light work has been amazing in terms of lighting up my body and teaching it how to activate itself (in a way nothing else has, including physio). But, on the other hand, I'm still at the point where I need to hold things in place in order to get that full activation. I think that if I'm not careful with how I apply OS, it'll just exacerbate this gap between weak and strong muscles.
However, when I read that article about reflexive strength, it describes perfectly how I built this dysfunctional body in the first place, with some muscles being phenomenally strong and others being non-existent. I'd love to get to a place where my entire body is working as a unit and I can return to that reflexive sort of training that I gravitate to.
No worries. I can't recall off the top of my head if it was in this very thread, but I commented somewhere about how even though the goal of OS is reflexive strength, that won't help as much if you're doing your practice locked into certain postures. If the brain doesn't sense a posture, it can't sense the muscles the way it needs to in order to gets things working more effectively. So you are also right that you might have to be conscious of getting things in the right place to get to where you need to be. I am also in a similar boat, where I need to be extra conscious of my left side for it to work optimally. The end goal, however, remains for things to be more "automatic," at least for me.
Where I have gotten things to "meet in the middle" is the hands and feet
sensing the ground. When standing, walking, running, etc your feet are literally the only thing connecting you to the world around you. When you crawl or do pushups or something, your hands take on that role as well. I find that when I sense the ground evenly between both feet and/or hands, most thing upstream tend to activate more reflexively.
When I crawl or do pushups, for instance, instead of thinking about shoulder position as much (sometimes I have to more or less at different times) I think more about feeling the ground and pushing both the heel of my palm, and just as importantly, the spot just below my index finger, into the floor. When I push into the floor, focusing on that, my shoulders just seem to do their things more effectively and naturally. There seems to be some connection between external rotation of the shoulder and pronation of the hand.
That may not be a magic fix for you, of course, but maybe it sheds some insight. The brain needs the right sensory input in order to find and use underactive muscles. Sometimes finding the right movements or drills or whatever to make that happen can be tricky.
