This document describes the steps to perform the Ardha Matsyendrasana (Half Lord of the Fishes Pose). It involves sitting on the floor and twisting the body by placing one leg over the other thigh while bending the elbow and turning the neck to look over the shoulder. The pose is held for 30 seconds on each side. It helps tone the spine, relieve back pain, and support organ function but should be avoided by pregnant women or those with certain medical conditions.
