Miley Cyrus left Winsor Pilates in LA yesterday following a workout. She carried a bottle of SmartWater and headed to her car in a tiny, tight dress. Miley flashed her abs earlier in the week showing off the results of all her labor in the gym. She's keeping up with her fit boyfriend Liam Hemsworth, who also showed off his sexy muscles in his box office smash The Hunger Games. Miley and Liam share a love for fitness and recently took a romantic walk with one of her pups, Floyd.
