Playgrounds aren’t just for kids. According to a June 29, 2012, article in the New York Times, New York City has plans to provide its citizens with “adult playgrounds” geared toward helping improve grown-ups’ fitness levels. The first park, located at Macombs Dam Park in the Bronx, was built several years ago as a test. The interest in the 15-piece playground has been so great that the city plans to scatter about 24 more of them throughout its five boroughs. This fall, the second adult playground will be built at John Jay Park on the Upper East Side and will include amenities like exercise mats and chess tables.

The cost of the playgrounds ranges from $75,000 to more than $200,000. According to the New York Times article, a children’s playground in New York or Los Angeles can cost anywhere from $300,000 to $2 million to build.
