The most effective and healthiest way to lose weight is to exercise to lose weight. Exercise can help burn fat and improve human metabolism. Remember to do more outdoor fitness exercises. Aerobic exercise is the most effective exercise to lose weight, especially those that consume more energy, such as jogging, mountain climbing, brisk walking, ball games and swimming. It is best to finish every exercise continuously without stopping in the middle. Every exercise must consume 300 kilocalories. Usually, this kind of exercise leads to a rapid heartbeat or sweating. Exercise can improve the metabolic rate of human body, but the effect is only two days at most, so the most important thing is to keep exercising. If you can't do it every day, do it at least once every two days. For an extremely obese person, even walking can be a great burden. Therefore, when choosing the type of exercise, we should do what we can, or focus on physical load, and gradually increase the amount of exercise to avoid cardiopulmonary overload or muscle and joint injury.
