Origin: Judith Lasater, a PhD of Eastern-Western psychology, physical therapist, and a founder of Yoga Journal, is the authority on this relaxing, therapeutic form of yoga, which originated in the States the 1970s.
Philosophy: The goal is to combat the physical and mental effects of everyday stress and ease common ailments such as headaches, backaches, anxiety, and insomnia with the use of restful poses and deep breathing techniques.
What to Expect: Don't come prepared for a workout—these quiet classes are all about rejuvenating the body in a group "nap-time" environment. Expect to use lots of props (bolsters, blankets blocks and straps) to relax into passive poses while the teacher guides you through your body, encouraging release.
Try it if…
… you love the last ten minutes of a yoga class—savasana. The entire hour-long restorative class requires nothing but letting go.
