Fitness: Locate Fitness Centers with Gym Ticket
This was on Lifehacker and the only problem that I found with this post is that gymticket.com does not have all the gyms or fitness centers in its database.
I workout at Fitness 19 and none of their locations are found in their database near me. It would be good, but they need to do a better job at including more locations then the couple major chains.
