This is the cockerel pose. Sit in padmasana. Put your hands through the space between the thighs and calves. Push the hands down until the elbows and then press through the hands so that your whole body lifts off the ground and you exhale. Stay here breathing easily for as long as you can. Then lower down slowly and come out of the pose.
Precaution: Heart conditions, high blood pressure, prolapse, hernia or back pain.
Benefits: strengthens the wrists and abdominal walls, arm and shoulder muscles, and opens the chest. Improves a sense of balance and stability.
