Abstract: A mat for learning, teaching, and performing yoga is provided in which the upper surface of the mat includes visually discernable floor-contacting body part markings. Sets of the markings can be used by yoga practitioners to facilitate proper positioning for one or more yoga poses. In another aspect of the invention, mats can be made for practitioners of different sizes and abilities by varying the spacing of the sets of markings for the poses. Further, an image of the mat can be represented on another medium, such as a card, poster, or video, on which a pose is depicted and the representations of the markings of the mat for that pose can be highlighted.
