This asana is also called half butterfly pose in English. This asana helps in stretching, strengthening and lengthening the body. This helps open up the hips and hamstrings, and thoroughly stretches the inner thighs, groin and knees. Also, the spinal cord becomes longer and its flexibility increases. This asana makes the body flexible.
According to the Ministry of AYUSH, Ardha Titli Asana (Half Butterfly Pose) is an important micro exercise. In this, one foot is placed on the thigh and the knee is moved up and down. This provides relaxation, loosens the tight muscles of the body and strengthens the leg muscles.
This is a great exercise to do before meditation. Doing this daily improves sitting posture and also provides relief from chronic pain. This asana is especially beneficial for those people who have difficulty sitting cross-legged. Doing Half Butterfly Asana every morning and evening not only gives relief to the back, but also increases flexibility in the body and helps in meditation.
