Show answer & explanationAnswer & explanation
Correct answer: D. Strengthened heart muscle and improved blood circulation.
Cardiovascular exercise, also known as aerobic exercise, directly works the heart and circulatory system, leading to a stronger heart and more efficient blood flow.
Why the other options are wrong
- A. While some cardio may build endurance, strength training is the primary method for enhancing muscle mass and strength.
- B. Weight-bearing exercises are primarily responsible for increasing bone density, not cardiovascular exercise alone.
- C. Regular, low-impact exercise can help joint health, but this is not the primary benefit of 'cardiovascular' exercise.

Cardiovascular exercise (aerobic exercise) is any activity that raises your heart rate and keeps it elevated for a period, strengthening the heart and improving circulatory health.
- Strengthens the heart and lungs.
- Improves blood circulation.
