How are aerobic activities different from anaerobic activites?

Aerobic exercise is any activity that uses your arms and legs to move your body. Your muscles are used in continuous  rhythmic or repetitive motions, increasing your heart rate and respiration while building your physical endurance

Anaerobic exercise targets your individual muscles.
Anaerobic exercise builds muscle through short bursts of strenuous activity like weightlifting or performing push-ups at high levels of intensity.
