Eight Angled Pose. This asana is dedicated to the sage named Astavakra and is an arm balance with a lateral twist. Astavakrasana requires you to hover the weight of the lower body using the support of the upper arms. This asana really strengthens the wrists, hands, arms, upper back, improves balance & tones the abdominal muscles. Given the twisting of the spine, Eight-Angle pose is a powerful aid of digestion & the elimination of toxins from the body.
