What is the significance of using low weight and high reps during endurance training?

Utilizing low weight and high repetitions during endurance training is significant primarily because it enhances muscular fatigue resistance. This approach emphasizes the development of the muscle's ability to sustain prolonged activity by increasing the oxidative capacity and endurance of the muscle fibers. When lighter weights are lifted for more repetitions, the muscles adapt by improving their efficiency in utilizing oxygen and better managing metabolic waste products, which contributes to an increased resistance to fatigue during extended physical activities.

This method of training specifically benefits activities that require sustained effort, such as long-distance running or cycling. As a result, training with low weight and high reps effectively conditions muscles to perform longer without fatigue, making it essential for athletes and individuals engaged in endurance-based sports.
