Originally developed by Taoist yogi Paulie Zink, Yin yoga aims to improve flexibility by stimulating the connective tissues to help increase circulation in the joints. Holding specific seated and supine postures for anywhere from 3 – 10 minutes at a time while practicing deep breathing is said to improve the flow of Qi: the subtle energy that travels along the body’s meridians. Yin Yoga is a deeply relaxing, yet invigorating practice that is intended to supplement the average Western Yang lifestyle. Yin Yoga differs from Restorative Yoga mainly in the level of challenge of the poses offered. Not recommended for beginners.
