A commonly recommended exercise for improving cardiovascular endurance is running. Running is an efficient aerobic workout that elevates heart rate and enhances lung capacity, thereby benefiting cardiovascular health. Other effective cardiovascular exercises include cycling, swimming, and rowing, all of which improve overall stamina and endurance. Incorporating these activities into a regular routine is essential for maintaining heart health, increasing energy levels, and improving overall physical fitness, making them integral components of a well-rounded exercise program.
