Reading the recent posts on this thread, it's clear that people have varying experiences with PT/exercise, depending on the therapist. And only if the person is pretty clear, and assertive will they get the desired outcome, which often is hard when dealing with experts in their field.
One thing I have noticed, (being a very active person who isn't that into structured exercise) is how difficult recovery seems to be for those who are used to going to the gym/exercising regularly. 3 of my 4 kids really view their running, gym time as necessary for their mental health, as well as physical, and I think that is a big part of things for many people. And legitimately so.
I can only imagine how frustrating it must be for folks to find the healthy balance/recipe for exercise that doesn't risk damage while still fulfilling this need.
