What is the term for the maximum weight that can be lifted through a complete range of motion for a desired number of repetitions?

The term that best describes the maximum weight that can be lifted through a complete range of motion for a desired number of repetitions is known as the One-repetition maximum, or 1RM. This concept is fundamental in strength training and exercise science, as it serves as a benchmark for assessing an individual's maximal strength capabilities.

The 1RM is critical for designing effective resistance training programs because it allows trainers and athletes to set appropriate weight loads for various exercises based on a person's strength level. By knowing a person's 1RM, it is possible to determine the appropriate percentage of that maximum to use for different training focuses, such as strength, hypertrophy, or muscular endurance.

In contrast, while muscle endurance refers to the ability to perform repeated contractions over time or maintain a specific task over an extended period, it does not specifically address the maximum weight lifted. Likewise, the resistance threshold and training volume pertain to different aspects of training; resistance threshold relates to the minimum load needed to induce any muscular adaptations, while training volume is the total amount of work performed, often calculated as sets times repetitions. Thus, the One-repetition maximum is the most precise term for maximum weight lifted for a complete range of motion in the context of strength training.
