Revolved Side Angle Pose, also known as Parivrtta Parsvakonasana, can be a tough one to get into, but feels amazing once you are there. It’s most often done as part of the Ashtanga Primary Series. This pose stretches and strengthens the legs, knees, spine, lower back, ankles and core. It can help with digestion and sciatica as well. If you have trouble achieving the full pose, try popping your back heel up until your body becomes more flexible.
