Which term describes the maximum weight that can be lifted once?

The term that accurately describes the maximum weight that can be lifted once is known as the one-rep max. This term specifically refers to the greatest amount of weight that an individual can lift for a single repetition of a given exercise. It serves as a benchmark for assessing an individual's maximal strength level and is commonly used in strength training programs to determine appropriate weights for various exercises, thus helping trainers design effective workout plans tailored to the individual's capabilities.

Understanding this term is crucial because it is foundational for strength training principles, guiding individuals in progressively overloading their muscles to promote growth and improvements in strength. Knowing an individual's one-rep max can also help in calculating training loads for multiple repetitions and ensuring safe lifting techniques during workouts.
