What does one repetition maximum (1 RM) refer to?

One repetition maximum (1 RM) specifically refers to the maximum amount of weight that an individual can lift for a single repetition of a given exercise, signifying their highest strength capacity at that moment. This measure is crucial in strength training and fitness assessment because it reflects the individual's peak strength level for that particular movement, allowing for establishing training loads and intensity levels effectively.

By identifying the 1 RM, trainers and athletes can design workouts that target specific strength adaptations, track progress over time, and set realistic goals. This concept is fundamental in sports medicine and athletic training, enabling practitioners to optimize performance while minimizing the risk of injury associated with improper loading.
