I've never used a gym since school, nowadays when I get time I get exercise by walking the dogs or cycling.
Personally, I think the benefit of a gym would be more for the 'personal trainer' or whatever they are called, someone who can suggest what exercise, diet etc you need, monitor and condition your progress.
In our tower there is a fully equipped gym for the fire crew which we can use, but I've poked my head inside and it just looks like a bewildering assortment of machines - I would have no clue where to begin.
