Like any voluntary movement breathing better takes practice. The respiratory diaphragm like any other muscle needs a full range of movement to do what is what meant to do. When the posture is strained our breath is encumbered. We need to release tension and soften into better posture to breathe better. In the world of Critical Alignment Yoga the respiratory diaphragm is linked to the 3rd tension line, below the shoulder blades.This short 30 min practice will help you relax and breathe deeper.
This video starts by describing a little bit about the link between posture and breath and then bring the practitioner through some gentle Critical Alignment soft prop release to find easy , open space.
