To improve cardiovascular endurance, exercises such as running, cycling, swimming, and aerobic classes are highly recommended. High-intensity interval training (HIIT) can be particularly effective, as it alternates intense bursts of activity with rest or low-intensity exercises, maximizing cardiovascular benefits in shorter periods. Regular engagement in these activities helps to enhance heart and lung capacity, promoting better oxygen utilization. It's essential to gradually increase the intensity and duration of these exercises to prevent injury and ensure continual improvement in endurance.
