For performing this asana, begin with lying on your back and hands by the side of your body. Now bend your knees and while breathing in, lift your head and chest up. Now, keeping the chest alleviated, lower your head such that the top of your head touches the ground. Now, bring your hands and legs upwards and join them together. Your hands and legs should be parallel to each other. Hold the position for 15-20 seconds and then release.
