When it comes to exercise，most of us fit into one of the two groups — those who keep a regular exercise habit and those who think about being more active but can’t seem to have a plan to do it consistently. Whatever your attitude to exercise，there’s another form of physical activity that many of us car-loving people can do to get enough movement in general.

Studies have shown that putting away your car and walking, biking or taking public transport to work can have a significant positive influence on your health by improving spirits, reducing body weight and lowering the risk of heart disease.

It’s not surprising that taking a bus or a train regularly leads to a more physically active lifestyle. Just think about what comes with using public transport. Those who travel to work without a car walk to stations, climb stairs, often stand while waiting for their bus or train, and then finally travel on foot or by bicycle to their destination. Such active transport can make up for the inactive time spent in work and school environments.

There’s no doubt that the improving public transport system in the city is influencing the way people work and live. But though the public transport system is improving, it is not within easy reach of everyone who would like to use it.

Bike-sharing programs are also growing in popularity（普及）and helping to bridge a gap in the crowded city public transport system. These programs allow users to easily book, ride and return a borrowed bike. Bike-sharing programs help people who might still need to travel some distance between the end of the bus or the underground line and their final destination. They also offer an opportunity to residents and visitors to travel freely around the city without being trapped in a car.
