Exercise positively affects the body's cholesterol levels by improving the balance between LDL (low-density lipoprotein) and HDL (high-density lipoprotein). Regular physical activity can increase HDL cholesterol, often referred to as "good" cholesterol, which helps remove LDL cholesterol from the bloodstream. This shift reduces the risk of plaque buildup in arteries, leading to improved heart health. Additionally, exercise can aid in weight management and lower triglycerides, further supporting cardiovascular health. Incorporating aerobic or strength-training exercises into one's routine is a valuable strategy for managing cholesterol levels effectively.
