Does shorter rest make strength training more effective?
Shorter rests compress a session, but can change the repetitions or load completed later. Longer rests may help preserve performance, especially when strength is the priority. A clock describes elapsed time; it does not measure muscle growth. Compare the exercise, effort, completed work and outcome before choosing a rest rule.
Rest changes the next set
A set does not occur in isolation. A demanding row followed almost immediately by another row asks already-working muscles to repeat the task before much recovery. Keeping the weight unchanged does not guarantee that the second set contains the same number of controlled repetitions. Alternatively, lowering the weight to maintain repetitions changes a different variable. These are two ways that a shorter break can alter the training actually performed. Rest is therefore part of the dose description, alongside sets, repetitions and load. It is useful to separate fatigue from stimulus: making a session feel harder by removing recovery does not, on its own, show a larger long-term adaptation.
