Bhujangasana, the cobra, is the sixth of the 12 basic postures of hatha yoga. It is also the first of three back-strengthening exercises done as part of a normal yoga class. The main benefits of the cobra are to build strength and flexibility in the back. The resting posture before and after the three back-strengthening exercises is done by laying on the stomach, rather than the back.
