Walking is definitely a good way to keep fit, but walking can be divided into brisk walking and brisk walking. Walking can't achieve the effect of fitness, only walking quickly can play an exercise role to a certain extent. As a low-intensity fitness method, brisk walking has a good effect on the elderly and patients with chronic diseases.

A study by the University of Pittsburgh found that people who walk fast have lower mortality than those who walk slowly. Because brisk walking not only has a good exercise effect on cardiovascular and cerebrovascular diseases and respiratory system, but also does the least harm to the body compared with other sports.

In order to ensure the exercise effect, each brisk walk should last at least 40 minutes to 60 minutes. Many countries put forward the slogan of "6000 steps" or "10000 steps" every day, which is actually a quantitative treatment of exercise time. According to the frequency of taking about two steps per second, "6000 steps" means walking for about 40 minutes, while "10000 steps" takes more than an hour. People who have just started exercising can gradually increase the duration, starting with a brisk walk for half an hour. When walking fast, the heart rate should generally be kept at 120~ 140 times per minute, and sweating is the best. Middle-aged and elderly people with good physical conditions may not be able to achieve the effect of sweating through brisk walking. At this time, they can assist jogging, realize the combination of walking and running, and achieve better fitness goals.
