Little yogis can stretch and sing their way to well-being with this kid-size yoga mat and accompanying musical YogaKids video. Created by Marcia Wenig, one of the nation's first yoga instructors for children, the tape teaches tots how to twist into positions related to animals, leaves and flowers, and encourages them to exercise creatively—easy if you're four years old and resting in a yoga pose called downward dog.
