How Long to Rest Between Sets
Rest is programming, not laziness
Rest periods are a training variable, not dead time. The length of your rest directly determines how much force you can express on the next set, which determines the quality of that set, which determines the adaptation you get. Cutting rest short because it feels more productive is one of the more reliable ways to get less out of a session than you put in.
How long you need depends on what you just did. Heavier compound movements (squats, deadlifts, rows, presses) demand more from the central nervous system and from the largest muscle groups. They take longer to recover from between sets. Isolation work or single-joint exercises with lighter loads recover faster. Knowing which category each exercise falls into is most of what you need to set your rest intelligently.
General Guidelines by Type
Heavy compounds (85%+ of max, 1–5 reps): 3–5 minutes. This is not optional; the nervous system genuinely needs this long to express close-to-maximal force again. Shortchanging rest here costs you reps on the next set, which undermines the whole point of training heavy. If your last set was truly maximal, err toward the longer end.
Moderate compounds (6–10 reps, hypertrophy focus): 2–3 minutes. Enough to restore most of your capacity without losing the metabolic stress that contributes to muscle growth at this rep range. This is where most people can be flexible without a meaningful performance cost.
Isolation and accessory work (10–15+ reps): 60–90 seconds is typically sufficient. These movements draw on smaller muscles, and some accumulation of metabolic fatigue between sets is not necessarily a problem at this rep range.
Longer Rest Is Not Wasted Time
If you rest 4 minutes between squat sets and feel ready at 3, fine. Go. But if you need 4 minutes to do the next set well, taking 4 minutes is the correct call. Resting longer than the minimum needed is not inefficient. Doing a poor set because you rushed is. The time you spend resting is part of the session, not overhead.
Supersets as a Time Tool
If session length is a genuine constraint, pairing non-competing muscle groups lets you use one muscle group's rest period to train another. Alternating a pushing movement with a pulling movement (bench press and cable row, for example) allows close to full recovery for each while keeping you moving. This works well and is a practical way to fit more volume into a shorter window. Supersetting two movements that share primary muscles (squats and lunges, for instance) is just shorter rest by another name; it will cost you performance on the second movement.
The rest timer in MyoAmigo starts automatically when you log a set, so you do not have to watch the clock.
