The next time you see a big playground, take a closer look. It may have adult-size apparatuses. Playgrounds for adults have been cropping up in cities around the country—in New York City...Miami…and Seattle, to name just a few. These “multigenerational” playgrounds are purposely placed near children’s playgrounds to encourage adults to work out right alongside their children and grandchildren. Best of all—these outdoor gyms are free to the public. Try them out—some have cardiovascular equipment…benches for sit-ups…and adult-size chin-up bars. Why should children have all the fun?
