Bālāsana (Sanskrit: बालासन) or Child Pose,[1] is a kneeling asana in modern yoga as exercise.[3] Balasana is not described until the 20th century; a similar pose appears in Niels Bukh's 1924 Primary Gymnastics.[6] From a kneeling position, bring the forehead to the floor and relax the arms alongside the body, palms upwards.[8] If there is discomfort in the neck and shoulders, a rolled blanket may be placed on the backs of the lower legs, and the forearms can be stacked and the forehead rested on them.[12] Shasangasana (शसांगासन) or "Rabbit Pose", practised in Bikram Yoga, has the tailbone lifted until the thighs are vertical and the head and arms point back towards the feet, creating an intense flexion of the spine.
