Left foot, right foot, left foot, right foot…you can travel fast or slow. The movement of your feet gets you where you need to go. But it also gets you so much more! Walking is such basic, simple exercise that almost everyone can take part in it.

Walking helps you in many ways. First, it makes your heart stronger. Studies show regular walking lowers your chance of heart disease. Walking for 30 minutes per day also helps control blood pressure. It can reduce your chance of having a stroke or developing some cancers, too. Want to lose weight? You need to burn 600 more calories each day you eat. Walking is the easiest way to do that.

Walking helps your brain health. As people age, their brains don't work as well. One in 14 people over 65 years old suffers from memory loss. Older people who walk six miles or more per week keep their brains in better shape. Putting one foot in front of the other isn't difficult. You don't have to think about it, so you can consider other things. You can consider problems or think of ideas. You can think over conversations again or just remember funny things that have just happened recently.

Walking is also good for your wallet. It saves the cost of going to a gym. Walk quickly for 150 minutes each week to get a good workout. A pedometer(計(jì)步器) can get you started. Begin with trying to take 1, 000 steps in 10 minutes to set the right pace.

You can make walking part of your day. Instead of parking right next to your office, park a distance away and walk. Do not take the elevator, but walk. You can even have walking meetings. They are what they sound like. Rather than sit, you walk and talk things over.

Make walking a habit, and see how it makes you feel.
