To train endurance in athletes, the method involves long-distance running, interval training, and cross-training. Long-distance running promotes aerobic capacity and stamina, essential for maintaining performance in events. Interval training introduces varying intensities, improving the body’s ability to recover quickly and enhancing both speed and endurance. Cross-training diversifies the workouts, which can prevent injury and work different muscle groups. Incorporating these methods in a training regime effectively builds endurance while ensuring athletes are well-rounded in their overall fitness and recovery capabilities.
