Pay particular attention to correct breathing when running - keyword: diaphragmatic breathing. In addition, start running slowly and gradually increase the pace so that the blood circulation can better adapt to the "activity" mode. Regular training also protects against unpleasant pain in the side. This is because the redistribution of blood can be trained.
You should also stop eating one to two hours before jogging and only eat easily digestible snacks such as bananas. Your stomach should not be too empty or too full. Strengthen your abdominal and back muscles with gymnastics and avoid talking while running.
