To use these Empire Gym posters and prints, simply find a suitable wall in your gym area. Clean the wall surface first to ensure better adhesion if you're using sticky posters. Hang them up straight for the best visual effect. When it comes to maintenance, avoid exposing them to direct sunlight for long periods as it may fade the colors. If they get dirty, you can gently wipe them with a soft, dry cloth. Just be careful not to scratch the surface while cleaning.
