Hong Kong has a childhood obesity problem. The number of overweight kids has increased 30 percent in the last 20 years.

Academics are a priority in Hong Kong, with an emphasis on hitting the books over hitting the streets. But there are some students who realize how important it is to exercise, to be fit and to be healthy.

One example, of a super fit group is Street Workout Hong Kong. They build strength based on body weight by using park equipment. The group attracts people of all ages, all with the same goal of promoting fitness. Still, they remain an anomaly in Hong Kong.
