Regular cardiovascular training induces several physiological changes that enhance overall health. Key adaptations include improved *heart efficiency*, increased *stroke volume*, and lowered resting heart rate, leading to better *circulation*. Enhanced *oxygen uptake* (VO2 max) allows for greater endurance during physical activity. Additionally, consistent cardiovascular exercise improves *metabolic rates*, aids weight management, and boosts levels of *good cholesterol* (HDL) while lowering *bad cholesterol* (LDL). These changes collectively contribute to reduced risk of chronic diseases and improved overall cardiovascular health.
