Yin yoga opens up the deep, dense, rarely touched tissue areas of the body. Years of dedicated asana practice will make anyone healthier, stronger and more flexible, but at some point the muscles will have reached their limit of flexibility. New depths of postures, deeper ranges of motion, or increased flow of energy may only be achievable by focusing on the deeper tissues of the body. Yin yoga is the perfect complement and balance to more active yang practices, and stands as a practice all by itself. Postures are held for longer periods of time, and repeated for maximum effect.
