The best way to find a 24 Hour Fitness location is to use the Club Finder on the official website of 24 Hour Fitness. On the homepage at 24hourfitness.com, locate the Club Finder under the Locations tab. On the Club Finder page, input your ZIP code or city and the nearest gym locations appear on a map. Narrow the locations on the map by club type, such as Active, Sport, Super-Sport and Ultra-Sport.
For a listing of locations, click the Join Today link in the upper-right corner of the 24 Hour Fitness homepage. A listing of nearby clubs based on your location automatically appears. Unless you are running a proxy or VPN that is hiding your geographical location, the results should be based on your current location. After you pick your preferred club, you are given an option to pick a membership type, and you can choose to purchase it online.
24 Hour Fitness has over 400 club locations in 17 states as of 2015. The website does not currently list any new locations coming soon for states outside of the current 17 states with club locations, but as of November 2015, there are plans to open club locations in California and New Jersey.
