What is the difference between aerobics and physical activity? How aerobic workout helps in physical fitness.

Physical activity refers to any bodily movement produced by skeletal muscles that requires energy expenditure. This includes activities undertaken while working, playing, carrying out household chores, travelling, and engaging in recreational pursuits.

On the other hand, aerobics is a specific form of physical activity. It is a fast-paced exercise that increases your heart rate to improve cardiorespiratory fitness. Examples include running, swimming, cycling, or any activity that gets your heart rate up.

Aerobic workouts help in physical fitness in several ways:

1. Improved Cardiovascular Health: Regular aerobic exercise strengthens the heart muscle, reduces the risk of heart disease, and helps control blood pressure.

2. Weight Management: Aerobic exercise burns calories, which can help you lose weight or maintain a healthy weight.

3. Increased Stamina: Regular aerobic exercise can increase your stamina and reduce fatigue.

4. Boosts Mood: Aerobic exercise can reduce anxiety and depression, boost mood, and promote relaxation.

5. Strengthens the Immune System: Regular, moderate-intensity aerobic exercise can be part of a healthy lifestyle that includes good nutrition and stress management to help boost your immune system.

Remember, it's important to start any new exercise program slowly and to gradually increase the intensity and duration of your workouts. Always consult with a healthcare provider before starting a new exercise program.
