Here are the two recordings in which I'm trying to reconstruct two breathing exercises: one where, after opening my chest, I release air on a "sss" while trying to keep the chest open the whole time, and the other where I do short pulses on "ss, šš, hi, ft" also trying to keep the chest open. I've been doing the exercises for about five days. I should mention that yesterday I really got into the second exercise with the short pulses — it feels very good and I have the impression it tones my transverse abdominal muscle. But when I start I overdo it, and this morning I woke up with a stiff neck muscle. I just learned it's called the sternocleidomastoid, which to my surprise is connected to the breastbone and collarbone and helps lift the chest — that is, inhalation. There you go. And it also hurts when I swallow. And I even feel some tention at the root of the tongue and the scull. The condition worsens as the day goes on. Well, I learned a new lesson in anatomy, but the one about patience still won't take root. Hope you don't make the same mistake.
