Slipped under the radar?? [About me getting kicked out of gym]

The gym never had the lat pull-down equipment that was usable for jamie. However, he worked around the problem and came up with his own exercise, which required a couple of helpers to lift him up in the chair to access it. The gym initially allowed him to do this exercise (I believe jamie mentioned that he had been doing this for a couple of years?), but eventually they decided that the exercise could not be permitted. (New management decision, based on potential liability?) Anyway, jamie’s take on the situation is that the gym is required, based on ADA laws, to either provide him with the handicap accessible equipment that he requires or continue to allow him to do the work around exercise that had previously been permitted.

As I understand it, this is the entire basis of his complaint, in a nutshell. Please correct me if I am mistaken in this interpretation.
