The strength training area and aerobic training area in the gym are usually separated. Dumbbells and barbells are used to show their teeth in the strength area of the gym, mainly to increase muscle strength and muscle circumference. Aerobic exercise is different. People who have been doing aerobic exercise for a long time will generally choose treadmills or spinning bikes when they go to the gym, and they will only be satisfied after running or sweating all over. These people seldom do strength training, but their physical fitness is no less than those who do strength training all the year round.

Most people do strength training to enhance muscle strength and muscle circumference. Actually, this is the biggest difference between strength training and aerobic exercise. Long-term strength training can make bodybuilders develop powerful and spectacular muscle shapes, but this does not mean that aerobic exercise can't exercise muscles. We see that runners in the gym are also very strong and well-proportioned, because the body fat rate is low and the muscle lines are looming. Because running is different from fitness strength training, you just can't train a muscle in isolation, so the difference in muscle mass is the most obvious compared with strength training.

Some people say that the muscular man in the gym looks muscular and has great strength. In fact, they are not as strong as a bricklayer and a cement worker. I don't agree with this. To say that endurance is stronger than willpower, some muscular men can't do it, but they have big muscles and greater strength. There is no doubt about it, unless it is a prosthesis. A person who does aerobic exercise for a long time, his muscles will not be as big as those of a muscular man, and his strength will not be great. Although he can run five kilometers at a time, he can't squat a 50 kg barbell.
