I rent a room in downtown of a big city and I simply don't have space for equipment (my room is mostly just bed with small kitchen and bathroom). Don't assume everybody is rich and owns a house with spare room / garage where you can put equipment.
I am 30+ years old and never lived in a place where I would have spare space for gym equipment. You must be very privileged if you have that (top 1% at least).
Thanks for downvote though.
If you're in a city there has to a playground nearby providing all sorts of options.
I think people just get too tied to a gym, when there are countless options to get really good workouts if the gym is unavailable for a period of time.
It is possible to get good workouts with minimal equipment.
