Answer 1

Aerobic exercise serves two main purposes; it conditions the cardiovascular system and aids in stress reduction.

Step-by-step explanation:

Aerobic exercise serves two main purposes; it conditions the cardiovascular system and aids in stress reduction. Aerobic exercises, such as cycling, walking, and running, increase muscular endurance and cardiovascular health. Regular aerobic exercise also reduces stress and improves mood by increasing the production of endorphins, which are the body's natural feel-good chemicals.
