Remember the “parcourse”?
Korean exercise equipment (par course)
In the 1970s they built a parcourse (or is it par course?) at the San Leandro Marina. We went there quite often. In fact, I think my mom went there virtually every day for several years. Perhaps they built these all over the USA at the time. I haven’t seen many since, but maybe they are still being built. Basically, they are outdoor exercise equipment.
In South Korea, outdoor exercise equipment is ubiquitous. You can’t find a park or riverbank without them. I have even seen indoor gym equipment (bench press bench with barbell locked by a metal cable to the ground) outdoors in Korea. This time of year they don’t seem to be getting a lot of use (due to the heat and humidity), but I’m guessing they wouldn’t be there if they weren’t well used the rest of the year. Or maybe the manufacturer just has some special relations with someone in the government.
