What type of exercise improves cardiovascular endurance?

Aerobic exercise is specifically designed to improve cardiovascular endurance. This type of exercise elevates the heart rate and keeps it elevated for a sustained period, which strengthens the heart and lungs, improves blood circulation, and enhances the body's ability to use oxygen efficiently. Activities such as running, swimming, cycling, and dancing fall under this category and are effective at building endurance due to their continuous and rhythmic nature.

In contrast, weightlifting mainly focuses on building strength and muscle mass rather than endurance. Yoga promotes flexibility, balance, and mental relaxation, but it does not predominantly focus on cardiovascular fitness. Pilates emphasizes core strength and stability and may include some aerobic elements, but it does not primarily serve as a method for enhancing cardiovascular endurance like aerobic exercises do. Thus, aerobic exercise stands out as the most effective type for improving cardiovascular fitness.
