If you want breathing exercises that go way into the specialized deep end, you can always pick up the sport of 3p rifle. You'll get incidentally very good at calming via breath, because of the tight feedback loop of holes-must-go-closer-to-the-center See e.g. Reinkenmeier describing breath work in standing: https://youtu.be/dHsG3GU9_PY?si=qlaLrSfKLCeiCgl4 https://youtu.be/dHsG3GU9_PY?si=qlaLrSfKLCeiCgl4 prone: https://youtu.be/5odRbYSbDIk?si=joBeFyyUrwBvQ7bk https://youtu.be/5odRbYSbDIk?si=joBeFyyUrwBvQ7bk Just general: https://youtu.be/JJ3zXuFsrfk?si=xdQ5NY0cHfK89CCg https://youtu.be/JJ3zXuFsrfk?si=xdQ5NY0cHfK89CCg The general points (deep from diaphragm, lean back, relax shoulders, etc) also carry over to other discipline like music (wind instruments at least).
