Exhale and lean forward from the waist. The sacrum bone should be above the hip and pointing towards the sky, move the hips a bit forward to keep the legs perpendicular to the ground. Rest your palms on both sides of your feet and open your fingers, making sure your back is straight (if not, bend your knees a bit). Push the ground back with your hands to help rest your head on your legs. Expire gently and slowly when performing this posture.
