Yin yoga asanas apply moderate stress to the connective tissues—the tendons, fascia, and ligaments—with the aim of increasing circulation in the joints and improving flexibility. They are also designed to improve the flow of qi, the subtle energy said in Chinese medicine to run through the meridian pathways of the body. Improved qi flow is hypothesized to improve organ health, immunity, and emotional well-being. A more meditative approach to yoga, Yin aims at cultivating awareness of one's inner silence, and bringing to light a universal, interconnecting quality.
