Interval workouts offer significant benefits for cardiovascular health by alternating periods of high-intensity effort with low-intensity recovery. This approach enhances aerobic capacity and improves heart efficiency, allowing for better oxygen utilization during exercise. The variability in intensity also boosts metabolism, leading to increased calorie burn during and after workouts. Furthermore, interval training can reduce the time needed to achieve fitness goals compared to steady-state cardio. Incorporating these workouts into a routine can lead to improved endurance, conditioning, and overall heart health.
