Parshvottanasana (Sanskrit: पार्श्वोत्तानासना, IAST: Pārśvottānāsana) or Intense Side Stretch Pose is a standing and forward bending asana in modern yoga as exercise.[4] A similar pose appears in Niels Bukh's 1924 Primary Gymnastics; Mark Singleton suggests that Krishnamacharya, influenced by the general gymnastics culture of the time, adopted gymnastics poses into his flowing style of yoga.The hands are pressed palms together in prayer position behind the back, fingertips upwards.The hips are aligned at right angles to the feet, so that the body can move downwards in a forward bend straight over the front leg.[5][3] The hands may be taken to the floor to intensify the stretch.
