Lightweight training benefits endurance athletes by promoting improved muscle endurance and minimizing the risk of injury. Engaging in high-repetition, low-resistance workouts enhances the stamina of muscle fibers without significantly increasing bulk. This approach leads to better energy efficiency during prolonged activities. Additionally, lightweight training facilitates the development of muscle control and coordination, which are crucial for endurance sports. Incorporating flexibility exercises alongside lightweight training can also contribute to better range of motion, ultimately enhancing overall athletic performance in endurance contexts.
