Yin Yoga targets the connective tissues, such as the ligaments, bones, and even the body's joints, that usually are not exercised very much in a more active yoga asana practice. Suitable for almost all levels of students, Yin Yoga is a perfect complement to the dynamic and muscular (yang) styles of yoga that emphasize internal heat and the lengthening and contracting of our muscles. Yin Yoga generally targets the hips, pelvis, and lower spine connective tissues. Poses are held from one to five minutes or more to give the tissues time to open gently with breath. After you have experienced it, even just once, you will realize that you have been doing only half of the asana practice.
