Can better consume glycogen in strength training, and can better mobilize body fat to participate in energy supply when returning to aerobic exercise. (As we all know, even aerobic exercise is basically powered by glycogen in the first 20 minutes), strength training is anaerobic, and there are intervals between each group of movements, which is difficult to last, and will not last for 2 minutes at the longest. Running training belongs to aerobic training and can last longer. In order not to affect the training effect, you can't stop halfway.
If you start training directly, it is easy to cause muscle strain. Of course, it is not easy to run for too long. If the strength and energy are exhausted in the early warm-up stage, then the strength training in the later stage will have no strength, which is not worth the candle. Beginners who start fitness are in worse health. After a long period of aerobic exercise, you must never do strength training for half an hour to 1 hour. Even experienced bodybuilders will not adopt this fitness sequence of "consuming a lot of physical strength first, then practicing strength".
If you can't keep up with your physical strength when doing strength training, it is difficult to lift the barbell even if your muscles are strong. This phenomenon is most obvious when you are squatting. Many people are exhausted by leg muscles and finally have no strength. After warming up, it's best to do strength training before running. Because strength training requires a lot of physical strength to maintain stability, including stricter requirements for the core area. Do strength training before running training.
