Mini-gyms spring up to offer quick and convenient access to exercise

A host of shared self-service mini-gymnasiums, each covering about 5 square meters, have sprung up in China's major cities, including Beijing.

Each features a mini exercise booth - which resembles a phone kiosk - a treadmill, air conditioner and purifier, and a high-definition screen to play games, listen to music or watch TV dramas.

With the basic fitness equipment needed to work out in a regular gymnasium, these mini premises can be booked and sessions paid for through smartphone apps.
