Typically, Planet Fitness locations are open on Presidents Day, as they often operate on regular hours for most holidays. However, it's always a good idea to check with your specific gym, as hours can vary by location. Some gyms might have altered hours or special promotions, especially during holidays. You can usually find this information on the Planet Fitness website or by calling your local gym directly. If you plan to visit on Presidents Day, confirming their hours beforehand will ensure you have a smooth experience.
