Improving cardiovascular endurance primarily hinges on engaging in consistent aerobic activity. Aerobic exercises, such as running, swimming, cycling, or brisk walking, elevate the heart rate over an extended period. This sustained effort enhances the efficiency of the cardiovascular system, allowing the heart and lungs to deliver oxygen more effectively to the muscles during physical activity.

The role of consistent aerobic activity is pivotal because it not only improves the endurance of the heart and lungs but also promotes better blood circulation and increases the overall stamina of an individual. This type of training leads to adaptations at both the muscular and cardiovascular levels, such as increased cardiac output and improved oxygen utilization.

While high-intensity resistance training can contribute to overall fitness and may support aspects of cardiovascular health, it is not specifically directed at enhancing cardiovascular endurance in the same way that prolonged, steady-state aerobic activities do. Likewise, longer rest periods can be beneficial for recovery in various training regimes but do not directly contribute to building cardiovascular endurance. Lastly, increased body weight can hinder cardiovascular efficiency rather than improve it, as excess weight may place added strain on the heart and reduce overall exercise capacity.
