The duo attended a sweat session with celebrity trainer Simone De La Rue, and showed off their killer workout style in the process. For the occasion, Swift flaunted her toned midsection in a cropped gray tank and matching leggings. She completed her look with a sweatshirt tied around her waist, Ray Ban sunnies, and pink and gray sneakers. Meanwhile, Kloss showcased her model-length gams in black leggings, a light blue T-shirt, laceless running shoes, and sunglasses.
Swift also took to Instagram to share a snap from their workout. "Words to live by and my favorite person to dance with!! @karliekloss @bodybysimone," she captioned a picture of her and Kloss looking at a motivational quote on the wall of the studio. Check it out below.
