Exercises best for improving endurance include aerobic activities such as running, cycling, swimming, and brisk walking. These exercises promote cardiovascular fitness, increase lung capacity, and enhance muscular endurance. Incorporating interval training, which alternates between high and low intensities, can further boost endurance levels and improve overall performance. Regularly engaging in these activities builds stamina over time, enabling individuals to sustain physical activity for longer durations and achieve their fitness goals more efficiently.
