Career
Grilley studied the slow-paced, less aggressive form of modern yoga called Yin Yoga under its creator, Paulie Zink, and later assisted with its development.[4][5][6][7]
He taught yoga to Sarah Powers, who devised the name "Yin Yoga" and went on to develop her own variant of it, Insight Yoga. Grilley had until then described the form as "Taoist Yoga".[8][9] He teaches Yin Yoga and trains yoga teachers with his wife Suzee Grilley. Their Yin Yoga curriculum covers the human anatomy of bones and muscles as well as seven asanas that they describe as archetypal, yoga and meditation.[10] He serves as a master teacher at Pranamaya.[11] From his knowledge of anatomy, Grilley states that it is not possible for everyone to do all asanas, because of variations in the shapes of specific bones; for example, some people have a much longer neck on the femur (thigh bone) than others, giving them, he argues, greater freedom of movement in the hip joint.[12]
Grilley has stated that Yin Yoga is not a franchise or hybrid like Aqua Yoga or Disco Yoga, and the use of the term is not restricted by copyright or trademark; instead, it is an additional way of practising.[13]
He has been interviewed and featured in magazines including Yoga Journal[13] and Elephant Journal,[14] and in chapters of books such as Victoria Bailey's 2012 Sharing Sadhana: Bailey describes him as both spiritual, as seen in his DVD on Chakra Theory and Meditation, and knowledgeable about the anatomical basis of yoga.[15]
