Restorative Yoga is a practice that is all about slowing down and opening your body through passive stretching. If you take a restorative class, you may hardly move at all, doing just a few postures in the course of an hour. It is a completely different experience than most contemporary yoga.
During the long holds of restorative yoga, however, your muscles are allowed to relax deeply. It's a unique feeling because props, rather than your muscles, are used to support your body. Restorative classes are very mellow, making them a good complement to more active practices and an excellent antidote to stress.
