Most Planet Fitness locations are typically open on July 4th, but hours may vary by location. Many gyms operate with reduced hours on holidays, so it's a good idea to check directly with your local Planet Fitness to confirm their specific schedule for that day. You can usually find this information on their website or by calling the gym directly. If you plan to work out on the holiday, confirming ahead of time will save you any inconvenience. Enjoy your workout!
