Yeah, that looks to me like an outdoor fitness installation, not a playground. Those aren't too hard to find, though, at least around where I live; most high schools or colleges of any size have one, and I've also seen a few near practice fields or parks popular with runners.

Back in the Seventies there was a fad for public fitness trails with a lot of the same equipment, which might do in a pinch. Those will be a lot more spread out, though, and a lot of them are in pretty bad shape four decades on.
