Walking 16 km every day is a considerable amount of exercise and requires a lot of energy and physical strength. For a healthy adult, this is equivalent to walking for about two hours every day.

This kind of exercise helps to improve heart and lung function, strengthen muscle and bone strength, and help to reduce stress and anxiety. However, this kind of exercise can also lead to physical fatigue, muscle pain and other health problems, so it should be gradually increased, and consult a doctor or professional fitness coach before doing this kind of exercise.
