To correct a wrong statement, aerobic exercise is not to increase muscles, but to increase red muscles (commonly known as slow muscles), while anaerobic exercise is to increase white muscles (commonly known as fast muscles). Red muscle is related to endurance, while white muscle is related to explosive force. Red muscles are much smaller than white muscles. Therefore, even if it is aerobic exercise for a long time, it is difficult to see that there is muscle because of the increase of red muscle.

For a very simple example, Becker, the world record holder of 5000m 65438+100000 meters, is only 1.7 meters tall. He can still sprint for 53 seconds in the last 400 meters to 5000 meters, with a pace of 180 steps per minute and a stride of 2 meters. He can't be so short without strong leg muscles. In fact, all long-distance runners feel that they have thin legs and no muscles, which are thinner than those who don't exercise. Because they exercise to strengthen the red muscle, the red muscle is very small, and because the fat content in the legs is low after exercise, the legs are thinner than those who don't exercise, but what is hidden under their thin legs is a powerful muscle, just a small red muscle. We should know that the perfect score of college physical education 1000 meters is 3 minutes 15 seconds, while long-distance runners can run 42. 195 kilometers continuously at a faster pace than the perfect score of 1000 meters, which of course requires strong leg muscles as support.

And sprinters like Bolt, because sprinting belongs to anaerobic exercise, have well-developed white muscles and thick legs. Short-circuit experts generally have thick legs because the white muscle is big.

Back to the topic of the landlord, traditionally speaking, aerobic exercise does not increase muscle, in fact, because aerobic exercise does not make muscle white, but increases red muscle. Because the red muscle is too small to be seen naked, let alone dressed. Anaerobic exercise such as strength training, due to the increase of white muscle, white muscle is big, and after training for a period of time, you can see the muscle increase with the naked eye.

If the landlord is only for health, it is recommended to give priority to aerobic, which is relatively less painful and easy to adhere to. Although others can't see the red muscle, they will feel much healthier after exercising for a while. If you want to have good muscles and help pick up girls for health, you can only do anaerobic exercise such as strength training, but every anaerobic exercise will produce a lot of lactic acid in the body, which makes people very uncomfortable, so you need to keep training with strong will.
