Natalie Grazian has a congenital limb difference, meaning her right arm did not fully develop before birth. Exercising has always been a passion and that prompted her to find modifications to help her do the activities she cares about. But when it came to some yoga positions and weight-bearing exercises, her limb difference presented a unique challenge. So the University of Washington graduate student worked with a prosthetic company to design a new type of prosthetic arm that will benefit fellow yoga fans across the world.
