The ideal yoga workout incorporates six types of poses, says Roger Cole, PhD, a psychophysiologist and yoga instructor. "Together, they improve alignment, strength, flexibility, and relaxation." Standing poses build strength and stamina. Balancing poses improve balance, of course, but also promote focus. Forward bends stretch back and hamstring muscles; back bends improve breathing. Twists aid in digestion and tone abs. And inversions increase circulation, leaving you calm yet energized. Weve designed a program with one pose from each group, plus modifications to make it easier for newcomers. Do each exercise once in the order given.
