Little Steps, Big Reward
① More than 145 million Americans take walking as part of their exercise, according to a recent report. That's 15 million more people walking than last year. Many places in America have reported an increase in walking. But most of the walkers are found in big cities like New York.
② Despite the increase in walking, only about 30% of Americans say they have at least 3 hours to take exercise a week. Our society been conditioned to be inactive. People rely on modern conveniences and become lazy. The inactive lifestyle has a negative aspect. We are more likely to be in poor health like overweight, which will threaten our life span.That's where walking comes in.
③ Walking is the best way to improve our health. Just 30 minutes of regular quick walking can help lose weight. At the same time, it can help lower the risk of heart disease and some cancers, and improve our blood pressure. If 30 minutes is too much, we may divide it into three 10-minute parts during the day. Most of us can find 10 minutes if we really try.
④ Walking requires only a pair of shoes and suits any schedules. Keep a pair of sport shoes at work. If you have a few minutes of free time, make use of them to take a quick walk. Even if you go to a health club several times week, you can still look for ways to be active while at work. It may be walking downstairs for a direct talk rather than sending an email.
⑤ Small efforts can make a big difference. But the hardest part for us is getting started. It's usually like this. When people get to a comfort level of walking for 10 minutes, they might think about trying 11 minutes. That first step is really worthy.
