Aerobic exercise is any activity that gets your heart pumping and helps your body use oxygen more efficiently.

It includes walking, running, dancing, swimming, and biking, not just aerobics classes.

When you do aerobic exercises, your heart beats faster, bringing more oxygen to your muscles to keep going longer without getting tired.

Over time, your muscles become better at using oxygen, which helps you move more and feel less tired during daily activities.

Aerobic activities also strengthen the heart. A strong heart pumps more blood with each beat, keeping the whole body healthier.

But that’s not all, regular physical activity is also key to keeping your muscles and bones in good shape.

When you use your muscles often, they grow stronger. Weight-bearing aerobic exercises, like jogging or dancing, help your bones stay dense and healthy.

This helps prevent injuries and reduce problems like weak bones when you get older.

Every step, jump, or pedal is a small move toward building a stronger body and feeling more active daily.
