Metabolism refers to ingesting useful "new substances" into the human body and expelling useless "old substances" from the body. Useful substances are protein, sugar, vitamins and other nutrients we get from food. These substances combine with oxygen entering the human body, and with the help of various biological enzymes in the body, they generate raw materials that constitute cells and energy sources that provide energy. At the same time, all cells in our body are frequently updated and alternated, and "toxins" are excreted. Only when synthesis and decomposition are balanced can health be guaranteed.

On the other hand, aerobic exercise and muscle exercise are two very important ways to improve metabolism. Increasing the quality and quantity of exercise is undoubtedly the most direct and fastest way to accelerate metabolism. At least "three times a week, 30 minutes each time, and the heart rate after exercise is above 130 times per minute", otherwise it is not good for your health. This short 30-minute exercise not only helps to burn calories and lose weight, but also has a great advantage that oxygen can be transported to the whole body after exercise, which greatly improves the metabolic rate and effectively burns fat, and the effect lasts for several hours. The general types of aerobic exercise include walking, running, cycling, swimming, fitness dancing, yangko, skiing and other low-intensity but long-lasting exercises. No matter men, women and children, aerobic exercise plays an important role in promoting physical health, enhancing physical fitness and preventing chronic diseases.

The two principles of muscle exercise include expanding muscle groups first and alternating muscle exercise. The muscle groups of legs, chest and back are all large muscle groups, and the exercise of these muscle groups will produce great load, so it is difficult to achieve the effect. Therefore, when you are energetic and can overcome the heavy load, please practice these muscle groups first. Don't practice with the same muscles all the time. Because the muscle groups that practice alternately can recover to a certain extent every time they practice, they can bear a greater load every second they practice. The development of muscle strength and volume is closely related to the intensity of training, so alternating exercise is beneficial to the increase of muscle volume and strength. Improving metabolism can not only burn body fat, but also improve physical fitness. Therefore, in order to improve metabolism, the habit with the most remarkable effect and worth adhering to is fitness.
