Generally speaking, the intensity and time of running can be different according to your physical condition and fitness goals. If you are a new runner, 6 kilometers and 40 minutes may be a relatively high level. But if you are a person with some running experience, this achievement may not be particularly outstanding.
No matter what your running performance is, it is important to keep moderate exercise and gradually improve your running ability and endurance in order to get better health and fitness effects. At the same time, we should also pay attention to reasonable diet and rest, and provide enough nutrition and rest time for the body to support the recovery and health of the body.
