Exercise influences cholesterol levels by potentially increasing high-density lipoprotein (HDL) cholesterol, the "good" cholesterol, while lowering low-density lipoprotein (LDL) cholesterol or triglycerides. Regular physical activity promotes better lipid profiles through improved metabolism and fat oxidation. Aerobic exercises like running, swimming, or cycling have shown particularly positive effects on cholesterol levels. The cumulative benefits of exercise can lead to a reduced risk of cardiovascular disease associated with unhealthy cholesterol levels.
