Regular activity positively influences cholesterol levels by increasing levels of high-density lipoprotein (HDL), commonly referred to as "good" cholesterol, while potentially lowering levels of low-density lipoprotein (LDL) or "bad" cholesterol. Engaging in consistent physical activity can help improve overall lipid profiles, reducing the risk of cardiovascular diseases. Additionally, exercise contributes to weight management, which is another key factor in maintaining healthy cholesterol levels. The overall effect of regular physical activity significantly supports heart health.
