I’d wager you have weak stabilizers CAUSING tight muscles. This why doing the same thing over and over isn’t working. You don’t need more “relax, release and loosen.” You need a different approach.
So hang along with me for a story involving plumbing that will miraculously explain the inner workings of the human body better than your 101 physio. class.
If what I take 45 minutes to fix in my clinic, as your therapist, you take the next 10 hours undoing, it’s a net loss and an eventual breakdown and fail.
