Half Boat (Ardha Navasana)
Sitting upright with a long spine and an open chest, bend your knees and bring your hands behind the thighs. Roll the shoulders back, tuck the chin toward the chest, and keep the spine elongated. With a deep inhale, lift the feet off the ground and hold the lower legs parallel to the floor. As you breathe in this position, keep the spine long and draw the shoulder blades together.
Keep the chin slightly tucked towards the chest. Release the pose when your body is ready.
Strengthens agni, and the abdominal and back muscles.
