Pūrvatānāsana is the counter pose to Paścimātānāsana. In Sanskrit, ‘Pūrva’ means ‘east’, this time referring to the east or front side of the body. By lifting and opening the chest with your inhale you will bring more lightness and ease to an otherwise difficult posture. Pūrvatānāsana benefits the heart and helps to strengthen and balance the muscles around the spine.
