Restorative yoga is a delicious way to relax and soothe frayed nerves. Also described as yin yoga, restorative classes use bolsters, blankets, and blocks to prop students into passive poses so the body can experience the benefits of a pose without having to exert any effort. A good restorative class is more rejuvenating than a nap. Studios and gyms often offer them on Friday nights, when just about everyone could use some profound rest.
