Although yin yoga is considered a restorative style, this class can be quite challenging. A whole range of asana poses are explored and usually one part of the body is the focus for the entire class. Once in the asana, the practitioner is asked to stay in this stillness and breathe holding postures between 3-8 minutes. These long holds give time to unravel and let go of tensions. Unlike restorative yoga, where students are encouraged to be 100% comfortable, Yin Yoga allows for discomfort and encourages attention throughout.
