Of course, everyone's stride width is different. 70 cm is just a rough idea. Girls' stride width will be relatively small, about 50 cm, so the number of kilometers coming out is about 5 km. Relatively speaking, moderate running is beneficial to physical and mental health. If the amount of exercise is too large, it will not only be beneficial to the body, but will increase the burden on the body.
Precautions for walking
When we walk, we don't take small steps, but cross our legs and stride out. In addition, swing your arms back and forth when you walk, and don't hang on your sides. This kind of exercise is more conducive to maintaining the coordination of limbs and exercising upper limbs.
In a word, walking, as a common way of exercise, is familiar to us, and it has many benefits. However, when we walk, we should try to avoid some walking taboos and exercise in the right way, which is more conducive to strengthening the effect of fitness.
