Utkatāsana

Fierce pose or chair pose. In Gheraṇḍa Saṃhitā 2.23-24, utkatāsana is described as the posture where the yogi sits upon the feet as on an invisible chair, with the thighs parallel to the ground. It strengthens the legs, stabilizes the pelvis, and activates mula-bandha. Its name derives from utkaṭa — fierce, intense — alluding to the intensity of sustained effort.
