Exercise in which a load is increased in predetermined steps. Ideally, the increments should be large enough to ensure overloading (see principle of progressive overload), but not large enough to cause damage. Progressive resistance exercises in weight-training are generally based on the repetition maximum (RM). In one session, several sets of exercises are performed, each at a higher intensity than the preceding one. The following example consists of three sets of repetitions with a short rest of 1–2 min between each; set 1 at 50% 10-RM; set 2 at 75% 10-RM; and set 3 at 100% 10-RM. Between sessions, the 10-RM is re-evaluated to ensure that the training conforms to the overload principle. See also principle of progressive overload.
