Yes, Planet Fitness gyms are typically open on New Year's Day, but hours may vary by location. Many locations operate on holiday hours, often opening later or closing earlier than usual. It's a popular time for people to start their fitness resolutions, so most gyms aim to accommodate members.
To ensure you have the most accurate information, it's best to check your specific Planet Fitness gym's website or call them directly. This way, you can confirm their holiday hours for New Year's Day and any other special promotions they might be running to kick off the new year. If you're planning to visit, consider arriving early, as gyms can get busy with post-holiday fitness enthusiasts.
