The chest as the seat of the breath
In the Iyengar tradition, the chest is understood as the seat of the breath — and the breath as the bridge between the body and the mind. When the chest is compressed and the sternum is sunken, the breath is restricted. When the breath is restricted, the nervous system cannot fully shift into a state of ease. Opening the chest is therefore not merely a postural correction; it is a direct intervention on the nervous system.
The February 2025 newsletter practice — a standing sequence focused on "vital joints" — demonstrated this connection directly. Students who arrived with tight chests and shallow breathing left with open chests, deeper breath, and a measurable shift in their energy and mood. This is the Iyengar tradition at its most practical.
The standing sequence for chest opening
The following sequence, drawn from the Iyengar lineage and the February 2025 practice, progressively opens the chest through the standing poses:
Tadasana with Urdhva Hastasana (Mountain Pose with Arms Overhead): Begin by standing in Tadasana, lifting the sternum and drawing the shoulder blades down and toward each other. Then raise the arms overhead in Urdhva Hastasana, keeping the shoulder blades descending even as the arms rise. This creates the foundational chest lift that all subsequent poses build upon.
Utthita Trikonasana (Extended Triangle Pose): In Triangle, the upper arm reaches toward the ceiling while the thoracic spine rotates open. The key action is rolling the upper chest toward the ceiling — not just reaching the arm up, but turning the entire front body to face the sky.
Utthita Parsvakonasana (Extended Side Angle Pose): This pose creates the maximum lateral opening of the chest. The upper arm extends alongside the ear, creating a long line from the outer heel to the fingertips. The chest must remain open and facing forward, not collapsing toward the floor.
"The chest must be like a dome — broad, lifted, and open. Not puffed, but expansive." — B.K.S. Iyengar
Supported Setu Bandha Sarvangasana (Supported Bridge Pose): Close the standing sequence with this supported backbend. With a block under the sacrum, the chest opens passively and the nervous system shifts into deep rest. This is the pose that consolidates the chest opening created by the standing work.
