It's about slowing down and opening the 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. During these long holds, your muscles relax deeply. It's a completely different feeling from other types of yoga classes since props are used to support your body instead of your muscles. Restorative classes are very mellow, making them a good complement to more active practices and an excellent antidote to stress. Appropriate for all levels.
