Fortaleza Rehabilitation and Fitness Center

Philadelphia's gym listings cluster hardest in a handful of zip codes. Zip 19103 leads with 21 gyms, followed by 19107 with 15 and 19123 with 14. Zip 19130 has 13, 19147 has 12, and 19106, 19134, and 19148 each carry 11. If you're near Center City or Rittenhouse, the 19103 cluster gives you the most options to compare within walking distance; elsewhere, checking your own zip against this list tells you whether you're in a dense area or need to widen your search a few miles out.

Out of 399 gyms listed for Philadelphia, 371 show a phone number and 350 list a website, so most entries give you a direct way to check hours, classes, or membership pricing before you call. Paid placements on this page display a Sponsored tag, and none are running here right now, so the order reflects the directory's standard listing data rather than anything bought. Call two or three gyms in your zip code to compare before committing. If you run one of these gyms and the phone number or website listed is wrong, you can claim the listing and fix it yourself, so the next person searching Philadelphia doesn't hit a dead end.
