I largely agree, and I’m not a big fan of “exercises” generally. You can’t try to relax and you certainly can’t force yourself to relax, but there’s a lot more to be said about the process of finding an easier way.
As @WhammyStarScream mentions, perception is key. We organise into posture and movement based on our tactile, proprioceptive and kinaesthetic perceptions. If we want to find the easier way to do something, we have to learn how not to do what we’re doing and increase our sensitivity so we can actually recognise what is easier. Then, with increased sensitivity we explore the space of possible movement solutions.
It totally does, it’s called Differential Learning.
