Latest in exercise: the mini-gym

Mini-gyms, which can be rented by the minute and booked using a smartphone, are springing up around Beijing, the latest addition to the so-called sharing economy.

Each is about 4 square meters and contains a treadmill or exercise bike, a TV and an air conditioner.

Seven of the one-person gyms have been installed by a company called Misspao; another company, Doubar, has opened two. They can be rented via an app or by scanning a QR code. Charges range from 1 yuan to 16 yuan (15 US cents to $2.40) per hour.
