Because aerobic exercise mainly refers to sports that rely on oxygen to participate in energy supply, such as running, swimming, cycling, skipping, boating, hiking and so on. The main purpose is to improve cardiopulmonary ability and endurance. Its low exercise intensity and long duration are his characteristics, which are mainly powered by oxidation mechanism. Moreover, fat is always decomposed, and it is replenished after eating, so reducing fat or increasing fat is only more than the other side. It is not that fat loss can only be achieved by aerobic, and anaerobic can also achieve the goal. And as far as sports goals are concerned, no method can be used by everyone, or it is effective in all cases. Choosing the most suitable exercise mode according to your own conditions is the most efficient way to lose weight. It is suggested to do mixed training here, that is, do aerobic training that suits you and do quantitative training. Combining anaerobic exercise with aerobic exercise can not only increase muscle strength, but also improve cardiopulmonary endurance, which embodies the characteristics of anaerobic and aerobic exercise and can achieve the goal of slimming as soon as possible under the same conditions.
