This document provides instructions for the Ardha Navasana (Half Boat Posture) yoga pose. To perform it: 1) Sit with your back straight and fingers interlocked behind your head. 2) Exhale and recline your spine back while raising your legs at a 35 degree angle so your head and toes are level. 3) Balance on your buttocks and hold for 10-30 seconds while breathing deeply into your abdominal muscles. The pose strengthens the abdominal muscles, lower back, reduces abdominal fat, and increases awareness, concentration, and balance both physically and mentally.
