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 and swimming. It is best to finish each exercise continuously, without stopping in the middle, and the heat consumed in each exercise must reach 300 kilocalories. Usually, this kind of exercise will lead to a faster heartbeat, or the degree of sweating will increase the metabolic rate of the human body, but the effect will only last for two days at most, so the most important thing is to persevere. 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.
