Uttanasana (Sanskrit: उत्तानासन; IAST: uttānāsana) or Standing Forward Bend,[1] with variants such as Padahastasana where the toes are grasped, is a standing forward bending asana in modern yoga as exercise.The name comes from the Sanskrit words उत्तान uttāna, "intense stretch";[2] and आसन; āsana, "posture" or "seat".[2][7] Theos Bernard however illustrates the related pose "Padhahasthasana" (sic) in his 1944 report of his experience of hatha yoga on the border of India and Tibet, suggesting the existence of a separate tradition.[8] The pose is entered from the standing position of Tadasana, bending forward at the hips until the palms can be placed on the floor, ultimately behind the heels.[6] Ardha Uttanasana is a halfway stage, the trunk horizontal and the palms resting on the calves.
