Hey,
I don’t know how to map a place like the one on the photo below. This is a kind of outdoor gym where basic machines may be used to exercise with one’s own body weight. An even simpler case is a place with trivial installations like a bar for pull-ups, fences to jump over, ropes to climb, etc.
The closest thing that comes to my mind is leisure=playground but I guess the playgrounds are usually for children.
Any ideas?
