High-intensity workouts provide significant cardiovascular benefits by improving heart health and increasing VO2 max levels. These workouts enhance blood circulation and reduce resting blood pressure. They promote better cardiac output and improve overall aerobic capacity. Regular engagement in high-intensity workouts can also lead to favorable changes in blood lipids, lowering bad cholesterol while increasing good cholesterol. Additionally, such workouts stimulate the release of endurance-related hormones, further contributing to cardiovascular efficiency and health.
