Utthita Parshvakonasana

It appears in the 20th century in Krishnamacharya's school of yoga in Mysore, and in the teaching of his pupils Pattabhi Jois and B. K. S. Iyengar, along with other asanas with names that describe the position of the body and its limbs.

[2][3] The pose is entered from Tadasana; the legs are spread wide apart, the feet are turned out as for Trikonasana and the arms are stretched out sideways.

One knee is bent to a right angle and the hand on that side is placed on the floor just behind the foot.

The upper arm is then stretched in line with the body straight out, above the ear.

[6] The opposite elbow is brought to the forward knee; this is a useful preparatory pose.
