Half Lord of the Fishes (Ardha Matsyendrasana) is a seated spinal twist: one knee bent with the foot outside the opposite thigh, the torso rotating toward the bent knee. It improves spinal mobility, may aid digestion, and opens the chest and shoulders. Named after the sage Matsyendra.

Ardha Matsyendrāsana.

To release, inhale, lift the left arm up, exhale, bring it down, release the legs, come back to Vajrasana. Repeat on the opposite side.
