Supported Fish Pose Lucile said, "Fish Pose is the one pose every person working long hours at a computer needs to do." It stretches all along the front of your body, especially your throat and shoulders, while also hitting your abdominals and the muscles between your ribs. "If you practice it regularly, it will open your shoulders and release upper back pain," Lucile explained. Lie on your mat with your back flat on the floor. Place a block beneath your mid-back and another beneath your head. Bring your arms close to your sides, palms facing down. Keeping your butt on the floor, inhale as you arch your back, pressing your hands and forearms into the ground. Keeping your legs strong, hold for five breaths, then relax your back.
