Exercises that improve cardiovascular endurance include aerobic activities like running, cycling, swimming, and brisk walking. These activities elevate heart rate and breathing, enhancing the efficiency of the cardiovascular system. Structured programs, such as interval training or steady-state workouts, can also be effective in building endurance over time. Consistency in engaging in these activities leads to improvements in heart function, lung capacity, and overall stamina, creating a strong foundation for sustained physical activity.
