Walking 20,000 steps is about15km, and walking fast (8km an hour) is 555 calories, so it is about1000k calories. Walking for 20 minutes at a speed of 4.8 kilometers per hour is the fastest, which is beneficial to thermal control and weight loss. It has been proved by many times that walking at the fastest speed will have better weight loss effect than running at the slowest speed.

Keep the speed at about 120 steps to 140 steps per minute. In addition to controlling the speed of walking, the distance of walking is also exquisite. It is generally recommended that people who want to walk to lose weight should walk at a distance of about 5 ~ 10 km at a time, and do not walk too far to avoid excessive fatigue or too short, otherwise they cannot lose weight. If you lose weight by walking, the faster you walk, the better the effect, but you should do what you can and gradually improve your requirements and speed according to your physical condition.
