From Dahn Yoga Basics book,
With this posture (3 to 5 minutes) concentrating on the stretch along the spine, open meridians that run along the front and back center of the torso.
Self check points:
1.Are you breathing comfortably?
Never hold your breath. Breath naturally and focus on exhalation.
2.Do you feel stiff in the posture?
Relax into the posture, focusing your mind on your breath. In this posture, it’s better to exhale through your mouth.
