A tight chest is not just a postural problem — it affects breathing, mood, and energy. When the thoracic spine is rounded and the sternum is compressed, the respiratory diaphragm cannot descend fully, breathing becomes shallow, and the nervous system reads this as a stress signal. The Iyengar standing sequence opens the chest from the back, creating a structural lift that lasts.
Frequently asked questions
Why does my chest feel tight even when I am not sick?
Chest tightness without a respiratory cause is almost always a combination of postural collapse and nervous system activation. When the thoracic spine is rounded and the chest is compressed, the respiratory diaphragm cannot descend fully, breathing becomes shallow, and the body reads this as a stress signal. Opening the chest is one of the most direct ways to shift the nervous system toward calm.
What is the difference between chest opening in yoga and just stretching the pectorals?
Stretching the pectorals addresses the front of the chest. The Iyengar approach to chest opening works from the back — by lifting and broadening the sternum, drawing the shoulder blades toward each other and down, and extending the thoracic spine. This creates a lasting structural change rather than a temporary stretch.
