What is the best way to improve cardiovascular endurance?

Engaging in aerobic exercise is recognized as the most effective method for improving cardiovascular endurance. Aerobic activities, such as running, swimming, cycling, and brisk walking, increase the heart rate and enhance the efficiency of the cardiovascular system by promoting better circulation and oxygen utilization. These exercises challenge the heart and lungs, leading to adaptations that result in improved endurance over time.

In contrast, weight lifting primarily focuses on building muscle strength and mass rather than enhancing cardiovascular stamina. Stretching is important for flexibility and injury prevention, but it does not elevate the heart rate sufficiently to boost cardiovascular fitness. Practicing yoga can offer some cardiovascular benefits, particularly in more vigorous styles, but it typically does not provide the sustained cardiovascular challenge necessary to improve endurance to the same extent as consistent aerobic exercise. Therefore, consistent engagement in aerobic activities is the most effective approach to enhancing cardiovascular endurance.
