Fast walking is not a sport based on fixed speed. Walking is an effort as fast as possible. If you walk faster, you will feel uncomfortable. It would be more appropriate to jog instead. Human movement includes various forms. Sports include swimming, weightlifting, high jump, ball games and so on. All these sports need sports facilities and equipment, so you should be prepared before exercise. However, you don't need these facilities and appliances to go quickly. As long as you open your legs and open your arms, you can exercise and get rid of fat.
