Cardiovascular exercise positively affects heart health by improving the efficiency of the cardiovascular system. Regular aerobic activities strengthen the heart muscle, allowing it to pump blood more effectively. This exercise also helps lower blood pressure and improve blood circulation, reducing the risk of heart disease. Additionally, cardiovascular workouts can enhance cholesterol levels by increasing high-density lipoprotein (HDL) cholesterol while lowering low-density lipoprotein (LDL) cholesterol. Engaging in regular cardiovascular exercise contributes to overall heart function and longevity.
