What does the term "repetition maximum" (RM) define?

The term "repetition maximum" (RM) specifically refers to the maximum amount of weight that an individual can lift for a defined number of repetitions during strength training. Typically, when professionals use this term, they might specify it as "one-repetition maximum" (1RM), meaning the heaviest weight lifted for just one complete repetition. The concept also extends to higher rep ranges, such as a 5RM or 10RM, indicating the maximal weight that can be lifted for five or ten repetitions, respectively.

This measure is critical in designing effective training programs, as it helps trainers to gauge an athlete's strength levels, determine training loads, and track progress. Understanding an individual's RM can assist in tailoring workout intensity to meet specific goals, whether that be building strength, power, or hypertrophy. The emphasis on "maximum" highlights the capacity to lift a certain weight without failing to complete the required repetitions, making it a vital term in strength training contexts.
