What type of exercise is essential for improving stamina?

Running is particularly effective for improving stamina because it is a cardiovascular exercise that strengthens the heart and lungs, thus enhancing the body's ability to deliver oxygen to muscles during prolonged activity. This increase in aerobic capacity allows individuals to perform physical activities for longer periods without fatigue.

In contrast, while weightlifting primarily focuses on building strength and muscle mass, it does not significantly enhance cardiovascular endurance. Activities like yoga and Pilates, though beneficial for flexibility, balance, and core strength, typically do not elevate heart rate to the extent required for substantial stamina improvement. Therefore, running is ideal for individuals looking to enhance their endurance capabilities in a focused manner.
