Butterfly pose – Baddha Konasana (also called Bound Angle Pose) provides a great stretch in the hips and thighs, and can relieve aching legs. It helps relieve stress and fatigue, and stimulates digestions.
If you have particularly flexible hips and knees, you can try elevating your feet on a block in Butterfly pose to deepen the posture. In other words, this variation of the classic pose takes this pose to the “next level” for students who are already very comfortable in the Butterfly position.
Be cautious here and only try this if you are very open and flexible in your lower body.
