(RM) (rep'ĕ-tish'ŭn mak'si-mŭm)
Maximum load a muscle can lift for a predetermined number of repetitions to the point of fatigue.
See: one-repetition maximum

repetition maximum

The greatest amount of weight a person can lift “n” number of times. The amount of weight that can be lifted exactly 10 times is 10 RM. The greatest amount of weight that can be lifted once is 1 RM. Repetition maximum can be used as a comparative measure of strength or as a technique in exercise prescription and strength training. During strength training 8 RM or 10 RM is used to develop strength, power, and muscle mass.
