Once upon a time, exercising used to have a uniform and a regiment specific for men and women. Men would suit up in short shorts, beach themed tank tops, white headbands, wrist-bands, calf high knee socks, and white New Balance shoes. Women would shimmy into their sleek leotards, heads decorated with colorful braided headbands, legs adorned with scrunchie leg warmers, and feet comforted by puffy, linen white high-tops.
