The gym comes to you in the sharing economy

Thanks to the fast-growing sharing economy, fitness buffs needn't necessarily "go to the gym." Many can enjoy the luxury of the gyms coming to them.

As the daily commute between work and home in mega-cities is already tiring, not everyone likes to travel extra miles to the gym, which restricts gymgoers' choice of places to work out.

"Don't (take the) risk to sign up for membership if the gym is not within walking distance to home or workplace because you know you will never go," said Dong Fang, a 26-year-old Shanghai-based real-estate manager.
