I have just finished creating a new tool for the site...
Muscle&Strength GymFinder!
This tool let's you search for gyms in your area. When you find the gyms near you, you can get their contact details and a map (using google maps) to the exact location.
There are already almost 21,000 gyms in the database, almost all from the US. I'll be getting in touch with gym owners from all over the globe to get some more gyms from other countries to add their gyms too.
Here are some examples of gym pages:

Enjoy!
