What training goal is promoted when resistance training intensity is below 67% of 1RM?

When resistance training intensity is below 67% of an individual's one-repetition maximum (1RM), the primary training goal that is promoted is muscular endurance. This training intensity allows for a higher number of repetitions to be performed, which is essential for developing endurance in the muscles.

Muscular endurance refers to the ability of a muscle group to sustain prolonged exercise over an extended period. By training with lighter weights, individuals can perform many repetitions, leading to improvements in their muscles' ability to resist fatigue. This contrasts with higher intensities of resistance training, which focus more on building maximal strength, hypertrophy, or power—goals that typically require heavier weights and lower repetitions.

In summary, training below 67% of 1RM is most effective for enhancing muscular endurance, as it allows individuals to focus on volume of work and the ability to sustain activity, making it suitable for athletes and individuals looking to improve their stamina.
