From the heart to the nervous system: this is how physical activity can regenerate tissues

Physical activity refers to any body movement that involves the muscular system and requires an expenditure of energy. This can include formal exercises such as running or lifting weights, but also everyday activities such as climbing stairs or gardening. The benefits are directly proportional to the intensity and frequency of physical activity; therefore a 20 minute walk a week will have lower positive effects than training in the gym 35 minutes 3 times a week.
