Which type of exercise primarily improves cardiovascular endurance?

Running is considered a type of aerobic exercise that primarily improves cardiovascular endurance. When you engage in running, your heart rate increases, which enhances the efficiency of your cardiovascular system. Over time, consistent running helps strengthen the heart muscle, improves blood circulation, and increases the lungs' capacity to take in oxygen. This type of exercise requires sustained effort over an extended period, which is essential for building endurance and improving overall cardiovascular fitness.

Other activities, such as weightlifting, yoga, and Pilates, tend to focus more on strength, flexibility, and balance rather than specifically targeting aerobic conditioning. While they may contribute to overall fitness, their primary benefits do not center on enhancing cardiovascular endurance to the same extent as running does.
