Apart from the mental health aspect (lack of agency, no time or space to yourself), you can’t always subject your kids to the weather of the day or they’re uncooperative to the point that the run isn’t feasible. Not to mention the multitude of reasons people can’t run, from disabilities to simply having no safe place to run with a stroller. Smooth sidewalks with space are kind of a luxury.

With a lifestyle and/or restrictions like that, no wonder people get out of shape. We can’t rely on our communities having space and accommodation for kids and so, well, without a family network we’re on our own.
