It is also performed in a cycle of asanas in Surya Namaskar, Salute to the Sun, as an alternative to Urdhva Mukha Svanasana, Upward Dog Pose.The backs of the feet rest on the ground, the legs outstretched; the gaze is directed forwards, giving the preparatory pose.[11] An easier variant is Sphinx Pose, sometimes called Salamba Bhujangasana (षलम्ब भुजंगासन),[13] in which the forearms rest on the ground, giving a gentler backbend.[15] Urdhva Mukha Shvanasana, Upward Dog, is entered with an inhalation from a prone position (or from Chaturanga Dandasana or Ashtanga Namaskara in a Surya Namaskar cycle), taking the feet a little apart.The legs are stretched out straight, the toes out (not tucked under), and the weight of the body is supported on the hands with outstretched arms so the hips are off the ground.
