Not in my Council area we don't, they privatised the council owned gym about 2 years back and subscriptions trebled for me as a pensioner. The fact is the new owners don't want us oldies so we are priced out of it.
My gym is full of "oldies" during the daytime, with some "Mummies" thrown in.
Although my local authority has handed management of the gym to an outside company, there is a special rate for people who have been referred by their GPs., currently about £20 per month and well worth while. after 3 classes, I'm in profit
