A lot of people don't have room for larger exercise equipment in their houses--if they have a house. Heck, I just had some reconstruction/reconfiguration done after a fire and I'm figuring out where to now put my rowing machine and I have a decent-sized house.

That many/most people don't really utilize their gym memberships is a separate issue from some people getting value out of them. You seemed to be arguing that gym memberships in general are stupid for anyone.

I apologize if my comments made you think I implied stupid, most definitely do not think that. I do however think you absolutely do not need gym membership to work out and I do believe that vast majority of gym memberships are waste of money. in my personal “circle” no one that works out regularly does so at the gym.
