Utthita Vasisthasana

Utthita Vasisthasana (sometimes shortened to Vasisthasana) or Side Plank pose is a balancing asana in modern yoga as exercise. The name of the pose comes from the Sanskrit उत्थित Utthita extended, वसिष्ठ Vasiṣṭha, a sage, and आसन āsana, “posture” or “seat”. The pose is not described in the medieval hatha yoga texts. It appears in the 20th century in the Ashtanga Vinyasa Yoga of Pattabhi Jois.
