You can run, and you must be prepared before running. This is the first thing. The second thing is to drink a cup of cold water after getting up, wash your stomach and eat breakfast properly to supplement your body's nutritional needs. After these things are done, start running. It should be noted here that the total running distance can be gradually increased from 1000m, but don't run too much at once, or your body will be overwhelmed. It is recommended to run at night, because oxygen is the most abundant at this time and the least in the morning. As important as exercise is rest and diet after exercise. Rest is easy to understand. As long as you don't often stay up late and let your trained muscle tissue get enough rest, you can make your muscles grow rapidly. In terms of diet, please eat more foods with high protein content after training, such as fish, beef and beans.
