भरद्वाजासन (Sanskrit, Bharadvajasana, “Bharadvaja's twist”)

“Bharadvājāsana is a seated spinal twist. It has three main forms:

“Bharadvājāsana I is the basic form in which the legs articulated as in Vīrāsana dropped to one side one foot on the floor and the other's ankle cradled in the arch of the foot below.

“Bharadvājāsana II is the advanced form requiring high hip mobility in which one leg articulated as in Padmasana (lotus position), while the other leg is articulated as in Vīrāsana (hero pose).

“Bharadvājāsana on chair is a variant performed sitting sideways on an armless chair. This does not require hip mobility; the arms grasp the back of the chair to assist with the twist.”
