In resistance training, what is typically the goal of using lighter weights with higher repetitions?

Using lighter weights with higher repetitions in resistance training primarily aims to enhance muscle endurance. This training approach focuses on the ability of a muscle or group of muscles to sustain prolonged exertion, which is essential in activities requiring stamina.

When performing exercises with lighter weights, the muscle fibers are engaged repeatedly over a more extended period. This type of training increases the muscle's ability to perform repeated contractions over time without fatigue. As the muscles adapt to this kind of training, they become more efficient at utilizing oxygen and managing energy resources, which contributes to improved endurance.

In contrast, training with maximum weights is more geared towards increasing strength, while promoting muscle hypertrophy typically involves a moderate weight with lower repetitions to encourage muscle growth. Flexibility training focuses on the range of motion in joints, which is distinct from the goals of resistance training.
