I tried a morning yin yoga class. And I was hooked. Yin yoga is much slower-paced than other more dynamic, heat-building (yang) styles of yoga (like vinyasa) and is predominantly floor-based.
Yin Yoga gives is a gentle form of yoga that makes you aware of every inch and angle of your body, as well as breath. It helps mindfulness to break the clutter and chatter of everyday hustle-bustle.
