The most effective exercise to lose weight is aerobic exercise, which can help burn fat and improve human metabolism. Friends who want to lose weight 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, swimming, etc. It is best to finish each exercise continuously without stopping in the middle, and the calories consumed in each exercise must reach 3 kilocalories. Usually, this kind of exercise will cause the heart to beat faster, or the degree of sweating will increase the metabolic rate of the human body, but the effect is only two days at most, so the most important thing is to persevere. For an extremely fat person, even walking may be a great burden. Therefore, when choosing the type of exercise, we should do what we can, or we should give priority to physical load and gradually increase the amount of exercise, so as to avoid the overload of the heart and lungs or the injury of muscles and joints.
