Thanks for mentioning Alfredo Escande's channel. It's very helpful.
Been adopting the classical posture for a month now, which I think gives me more stability of the guitar body as well as more room and flexibility for left arm and right hand, compared to steel string acoustic usual posture.
I especially agree with Alfredo Escande in that (it's also my discovery that the right) it is good to build up the most comfortable posture first, then place and manipulate the guitar into the equilibrium, not to adjust the body to fit the guitar.
I also agree with him that foot stool is not the culprit for back issues. Left leg up does not cause stress in spine but rather the uncomfortable rotation. In that sense, all kinds of guitar support would not solve the ergonomic problem, if the posture is still in certain way stressing the muscles.
