I think running is aerobic exercise, so if you want to gain muscle through it, it may not be very effective and will not have any effect. It can be said that you can hardly see the effect If you really want to gain muscle, I think going to the gym will be better and the effect will be more obvious. It will be better to have professional fitness guidance.

Because running is aerobic exercise, it has no effect on muscle training, or basically no effect, but it can strengthen the body. Running can exercise our bodies, and it can play a better role in exercising our bodies as a whole, but if it is for the purpose of exercising muscles, I am afraid it is hopeless.

I think if you want to exercise your muscles and your abdominal muscles, you'd better go to the gym for professional training. Find a professional fitness instructor and let him take you to work out. I believe this will achieve good results. The abdominal muscles you want, as long as you train according to professional fitness requirements, will be satisfied quickly in exercise.

According to the professional fitness method, I believe that with the coach's company and your own efforts, you will have chest muscles as big as many TV stars. If you just want to exercise your chest muscles by running, I advise you to let go. This will not succeed, nor will it be effective. Running can only exercise, but has no effect on chest muscles.

Trust me, go to a professional gym to exercise. I believe you will learn a lot there and get what you want. You will also develop the perfect abdominal muscles. The key is to stick to it, to have a reasonable diet and the right way to exercise, otherwise it will be in vain. I hope you can go to the gym to exercise, and I hope you can get a lot from it.

The above is purely a personal opinion. If you have any questions, please comment.
