Eka Pada Rajakapotasana (Sanskrit: एक पाद राजकपोतासन; IAST: Eka Pāda Rājakapotāsana), Rajakapotasana, or [One-legged] King Pigeon Pose is a seated back-bending asana in modern yoga as exercise. The Yin Yoga form of the asana is named Swan Pose, while the Aerial yoga variant, supported in a hammock, is Flying Pigeon Pose. The basic pose is described in the 20th century by two of Krishnamacharya's pupils, Pattabhi Jois and B. K. S. Iyengar; several other variants have been created. It is one of the yoga poses often used in advertising to convey desired qualities such as flexibility and grace.
