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. This class is very mellow, a good complement to more active practices and an excellent antidote to stress.
Restorative yoga is completely different. It's about slowing down and opening the body through passive stretching. In this restorative class, you may hardly move at all, doing just a few postures in the course of an hour.
