Which of the following is NOT a direct benefit of regular cardiovascular exercise?

• A. Keeps heart arteries healthy
• B. Lowers cholesterol
• C. Strengthens immune system
• D. Increases risk of heart disease

Answer: (D)

Regular cardiovascular exercise improves several direct aspects of heart and body health. Keeping heart arteries healthy comes from better arterial function and elasticity, which supports steady blood flow and lowers blood pressure. Lowering cholesterol occurs as the body improves its lipid profile, typically reducing LDL and triglycerides while raising HDL. Strengthening the immune system happens through improved circulation, which helps immune cells reach tissues more effectively. The statement about increasing risk of heart disease is not a benefit at all; regular cardio actually lowers that risk. So, the option describing an increased risk is not a direct benefit, while the other three describe real, direct benefits.
