Bikram Yoga Tip of the Day: Kapalbhati in Vajtasana Blowing in Firm Pose.
Marilyn has great intercostal muscles. |
Expiration:
1) The intercostal and diaphragm muscles relax.
2) The ribcage moves downwards and inwards and the diaphragm becomes relaxed.
3) The thorax volume decreases, causing the air pressure to increase to above atmospheric pressure, so air is forced out of the lungs.
4) Expiration is a passive process- it doesn’t require energy.
