Tidying
I did a fair bit of tidying on this article. I think my edit summaries are pretty self-explanatory, except that I wanted to elaborate slightly on the bits that I simply removed. 

I deleted additional details about Joe Gold except for the facts directly related to Gold's Gym. The deleted info is already included in the article about Joe Gold. 

This article still needs fleshing out to become something other than a stub. Future stuff to include might include:

 A photo of a typical Gold's Gym
 A well-documented criticism section
