How to adjust breathing when practicing yoga?

In the process of practicing yoga, the adjustment principles of breathing, sucking and exhaling are as follows:

Principle 1. Inhale when expanding and exhale when contracting and twisting. In the first bend, breathe in when your hand is up, and exhale when your body is bent in half.

Principle 2: emphasize the posture of a certain part. When the posture stays, it is accompanied by several deep breaths. For example, when doing dog pose, push your hips up and support your hands and feet on the ground. Seen from the side, this posture looks like a triangle. At this point, take four deep breaths here to strengthen the muscle lines of the back and legs.

Principle 3, difficult movements can breathe faster, and postures that emphasize balance can breathe deeper. If you compare shoulder breathing with tree breathing, of course, shoulder breathing will be more urgent and tree breathing can be more gentle.
