Navasana (Sanskrit: नावासन; IAST: nāvāsana), Naukasana, Boat Pose, or Paripurna Navasana (Sanskrit: परिपूर्णनावासन; IAST: paripūrṇanāvāsana "Full Boat Pose") is a seated asana in modern yoga as exercise.[4] To enter the pose from sitting, the knees are bent, and the body's weight is shifted back until the soles of the feet lift off the ground.In the pose, the body is balanced on the sitting bones, not leaning right back on to the tailbone.[6] Variations include the easier Ardha Navasana (Sanskrit: अर्धनावासन "Half Boat Pose") with feet and body only half-raised.[7] The more difficult Ubhaya Padangusthasana has both hands grasping the toes or feet.
