ISSA (International Sports Sciences Association)

Phoenix has 376 gym listings in this directory, and most come with a way to reach them directly: 353 list a phone number and 313 list a website. That kind of coverage means you can call two or three places near you, check hours, or scope out a site before you drive over, without hunting for contact info that isn't there. Listings cluster around zip codes like 85044 and 85032, so if you're comparing options close to home, those areas are a good place to start narrowing your search.

Paid placements are labeled Sponsored whenever a business pays for a boosted spot, so you'll always know the difference between a regular entry and one that's been promoted. Right now no gym in this category carries that tag, which means the order you're browsing reflects plain directory data, not a paid ranking. If you own or manage one of these gyms and the phone number is missing or the website link is outdated, you can claim the listing and update it yourself, so someone searching in Phoenix isn't stuck with bad info.
