In Asia, outdoor gyms are all the rage. (According to the NY Times they’re on their way to the States too)
In Seoul and Beijing, I’ve seen people exercising after work, on a lunch break, whenever, at these gyms located in park areas, by the riverside, or even on a random sidew. In Seoul, I tried it out along the Nam river (a metal elliptical-type thing) and felt good about getting in a few minutes of exercise on my trip 🙂
Here is an example of a small one, in Seoul.
In Phnom Penh, I’ve noticed people doing outdoor aerobics classes, which is more my style. Here they are dancing along the Mekong riverfront.
