Yin Yoga is the centering of your breath and body - aligning the physical and mental by practicing stillness or gentle movement for short periods of time. Props may assist in helping you to hold poses more comfortably. It is mostly done seated or laying, letting gravity do the work, not the muscles.Yin Yoga is a quiet and simple practice, but not necessarily an easy practice. Yin yoga works deeply into our body. It targets our deepest tissues of the body, our connective tissues — ligaments, joints, bones, and the deep fascia networks of the body — rather than the muscles.
