Yin yoga is the moon to vinyasa’s sun, the stillness to vinyasa’s movement, the ease to vinyasa’s effort, and literally the yin to vinyasa’s yang. So what is yin yoga? Yin yoga is a moderately passive approach to healing the body and mind. Through gentle stretches held for 3-5 minutes, yin yoga works to soften connective tissues (fascia) and increase pliability in your ligaments.
