Trikonasana is one of the most common practiced standing postures in Hatha Yoga. The posture may be difficult to perform due to different movements involved that may create blockage in easily reaching the full pose. However, a number of adjustments can be taken to fully enjoy the benefits and experience of Trikonasana.
The feet stand apart, with the hips externally (outwardly) rotated. The upper body will hinge from the hip over to the side of the front leg. Therefore, the front leg will get stretched (hamstrings), and the upper side of the body will stretch at the lower back and outer hip area as well as the side of the core (quadratus lomborum, obliques, and gluteus minimum and medius).
