Lie down in supine position on the floor with your legs pointing out, heels in contact. Bring your hands on either side of the chest, palms on the floor, in line with the chest. Taking a deep inhalation, move your head and shoulders backwards, without exerting pressure on the palms, just up to your navel. Hold the pose, breath suspended, for a count of 10. Exhaling deeply, relax and come back to the initial position.
