Vin/Yin is a yoga sequence that combines Vinyasa Yoga and Yin Yoga. This is normally done with Vinyasa as the first half of the sequence and Yin Yoga as the second half. The Vinyasa portion warms the body up and rids your body of excess Prana, or energy. After this, your body is ready to relax and lengthen during the Yin Yoga portion.
