Improves the blood circulation throughout the body

Explanation:

Regular exercise increases blood flow to bring oxygen to nearby muscle cells and tissues. As soon as the blood arrives, it must return to the heart to be pumped again. When an obstacle occurs in the circulatory pathways, the body creates alternative ways to try to maintain this flow, so new arteries and veins arise. For this reason, regular physical exercise improves the circulation of blood throughout the body.
