Answer:

arms, legs, and hips

Explanation:

During aerobic activity, you repeatedly move large muscles in your arms, legs and hips. You'll notice your body's responses quickly. You'll breathe faster and more deeply. This maximizes the amount of oxygen in your blood.
Aerobic exercise uses continuous, rhythmic movement of large muscle groups to strengthen the heart and lungs (cardiovascular system). When you exercise, your muscles demand more oxygen-rich blood which, in turn, makes your heart beat faster to keep up.
