This practice is designed to help you sit longer, and more comfortably, by stretching connective tissue around the joints (mainly the knees, pelvis, sacrum, and spine). A passive practice, Yin Yoga involves variations of seated and supine poses typically held for 3 to 5 minutes, accessing deeper layers of fascia. It is a wonderful class to improve your flexibility posture and leave you feeling deeply relaxed and re-balanced.
