If a person often gives priority to running, supplemented by strength training such as muscle building, his figure will be normal, because his body muscles will not be overdeveloped. He has seen many strong muscular men, and his body is covered with muscles, so he looks a little ferocious. This is the result of anaerobic training such as long-term strength training. If he mainly runs, his figure will be particularly normal, and he looks stronger and less ferocious.
Because running belongs to aerobic exercise, aerobic exercise is not conducive to the formation of muscles, and muscles will be lost, but the lost muscles can be replenished during strength training.
It can also enhance heart and lung function, because running is aerobic exercise. If a bodybuilder puts running first, then his cardiopulmonary function will be enhanced, aerobic exercise will enhance cardiopulmonary function, while anaerobic exercise can't do this, that is, cardiopulmonary function can't be strengthened in strength training such as muscle gain.
The similarity between the two is that they both improve their physical fitness. Whether it is running or strength training, anaerobic exercise will make their bodies stronger.
Health is the capital of revolution, or health is the most important!
