There's 169 gyms in Contra Costa County according to US Census (County Business Patterns), there are only four of them that we've been able to find listed below using the names as they appear on OSM. One has a phone number, another links up its own website. These listings are all free for anyone who wants to claim their page on the hashtag.org network.
