Different training methods can significantly influence muscular endurance by targeting various muscle fibers and energy systems. For example, high-repetition resistance training can enhance endurance by increasing the ability of muscles to sustain prolonged exercise. Conversely, lower-repetition training with heavier weights typically builds strength, which may not directly improve endurance. Additionally, circuit training combines both resistance and aerobic exercises, effectively improving muscular endurance while promoting cardiovascular health. Ultimately, tailoring training methods to specific endurance goals is key to developing lasting performance improvements.
