Muscle soreness is common, but it’s not a requirement for building muscle or getting stronger. This guide explains what soreness actually tells you, when it’s useful, and better ways to measure progress.
Muscle soreness (DOMS) is not required for muscle growth, strength gains, or fat loss.
Mild, occasional soreness can indicate a new or harder stimulus, but heavy soreness often signals poor recovery or programming.
The best indicators of progress are performance trends, progressive overload, and recovery quality—not how sore you feel.
You can build muscle very effectively while rarely feeling more than light soreness.
Managing soreness with smart training, nutrition, and sleep leads to faster long‑term progress.
This article explains the science of muscle soreness (DOMS), its relationship to muscle growth and performance, and practical indicators of progress. It uses current sports science principles such as progressive overload, volume management, and recovery to outline when soreness is useful, when it is a warning sign, and how to train effectively with minimal unnecessary soreness.
Many people chase soreness as proof of a ‘good workout’ and end up overtraining, under‑recovering, or quitting. Understanding what soreness really means lets you design smarter training that builds muscle and strength consistently without feeling wrecked after every session.
Delayed Onset Muscle Soreness (DOMS) is the stiffness and discomfort that typically appears 12–24 hours after a workout and peaks around 24–72 hours. It’s mainly caused by micro‑damage to muscle fibers and connective tissue plus inflammation, especially from unfamiliar or eccentric‑heavy movements (like lowering a weight slowly or downhill running). DOMS is a normal response to novel or challenging exercise but is not a precise gauge of workout quality. Some people are naturally more or less prone to feeling it, even when doing the same training.
Muscle growth and strength gains depend primarily on progressive overload, adequate training volume, and recovery—not on how sore you feel. Research shows muscles can grow and adapt even when soreness is minimal or absent. Soreness is influenced by novelty, exercise type, genetics, sleep, and nutrition. Early in a new program, you may get very sore without having done an optimal amount of work, and later you may progress well with almost no soreness as your body adapts. Therefore, using soreness as your main feedback metric is unreliable and often misleading.
Mild soreness—where you notice your muscles but can move normally—is common when you: start a new program, add sets or weight, introduce new exercises, or return after a break. This type of soreness can confirm you provided a novel stimulus without overdoing it. It’s often more noticeable in large eccentric movements (e.g., squats, lunges, Romanian deadlifts). As long as it doesn’t interfere with daily life or next workouts, occasional light DOMS is a normal side effect of training, not something to fear or chase.
Progress happens when you gradually ask your muscles to do more over time. This can mean adding weight, reps, sets, time under tension, or improving technique at the same load. You might not feel very sore as you progress because your body becomes efficient at handling the stress. Still, if you consistently lift more or perform more quality work over weeks and months, your muscles adapt—whether or not you feel DOMS.

Weekly volume (total hard sets per muscle group) and consistency are stronger predictors of muscle gain than soreness. For many people, 10–20 hard sets per muscle group per week, spread across 2–3 sessions, is effective. The key is repeating quality sessions regularly over months. Chasing extreme soreness often leads to doing too much in one workout, then needing longer to recover, reducing weekly volume and consistency.
Great for
You can mentally rate soreness from 0 to 4: 0 = none, 1 = noticeable but no impact on movement, 2 = moderate, slightly affects certain movements, 3 = strong soreness that alters how you move, 4 = severe, interfering with daily tasks. Ideally you sit around 0–2 most of the time. Occasional 3 can happen after a new block or big change, but frequent 3–4 suggests your training or recovery needs adjusting.

Never feeling sore doesn’t automatically mean you’re not progressing. Check objective markers: Are your loads, reps, or total sets increasing over weeks? Is your form improving? Are your measurements, photos, or performance better? If yes, you’re progressing—even without soreness. If not, you may need more volume, better effort near failure, improved technique, or a new progression plan, but not necessarily to chase soreness itself.
Constant soreness suggests your recovery is lagging behind your training. Common causes include too much volume too soon, not enough rest days, big exercise variety every session, low calorie or protein intake, or poor sleep. Reducing volume slightly, repeating exercises instead of changing them weekly, adding rest days, and improving nutrition often reduce soreness without hurting progress—usually they enhance it.
Record exercises, sets, reps, and weights each session. Look for steady upward trends over 4–8 weeks: more weight lifted at the same reps, more reps at the same weight, or more quality sets. This gives you objective proof of progress that doesn’t rely on how you feel day to day.

Filming key lifts or checking in with a coach lets you see whether your form is improving. Better stability, range of motion, and control at the same or higher loads are signs of adaptation, even if soreness is low.

Depending on your goal, track: body measurements (waist, hips, limbs), progress photos, clothes fit, resting heart rate, or how many push‑ups, pull‑ups, or meters you can do. For athletes, sport‑specific performance matters most. These indicators change more slowly than daily soreness but tell a clearer story over time.
Muscle soreness is largely a side effect of novelty and eccentric loading, not a direct measure of how ‘effective’ a workout was for growth or strength.
Programs that chase soreness often overload a single session at the expense of weekly volume, performance quality, and adherence—slowing long‑term results.
As your body adapts and recovery improves, you can train hard, add load, and progress consistently while experiencing less soreness, which is a positive sign of conditioning.
Objective metrics like performance trends, volume, and recovery status are more reliable—and more motivating—than relying on soreness as your main feedback tool.
Frequently Asked Questions
No. Muscle growth depends on progressive overload, adequate training volume, and recovery—not on soreness. You can build muscle effectively with minimal soreness as long as you’re gradually doing more work over time and training close enough to failure with good form.
Not necessarily. If your weights, reps, or performance are improving over weeks, you’re likely progressing even without soreness. If progress has stalled, adjust your program variables (volume, intensity, exercise selection) rather than trying to induce soreness specifically.
Extreme soreness more often indicates that you did too much, introduced too much novelty, or under‑recovered. It can reduce performance in later sessions and increase injury risk. Mild to moderate, short‑lived soreness is fine; repeatedly being unable to move normally is not the goal.
Light to moderate soreness is usually fine to train through, especially if you’re working different muscle groups or using lower loads. If soreness is severe and changes your movement, it’s wise to adjust intensity, reduce volume, or add rest until you can move with normal control.
Increase training volume and intensity gradually, repeat exercises consistently instead of changing everything weekly, prioritize 7–9 hours of sleep, eat enough calories and protein, stay hydrated, and include light movement, stretching, or low‑intensity cardio between hard sessions.
Muscle soreness can be a normal side effect of challenging or new training, but it is not required for progress—and chasing it can slow you down. Focus on structured progressive overload, solid recovery, and consistent performance improvements. If your numbers are trending up and you feel generally energized, you’re on the right track, whether or not you wake up sore.

Very high soreness—struggling to walk, use stairs, or straighten your arms—often signals excessive volume, intensity, or poor recovery. If you’re consistently that sore, you’re likely compromising performance in subsequent sessions, slowing progress. Red flags include soreness that worsens for more than 72 hours, sharp localized pain, swelling or dark urine (possible rhabdomyolysis), or pain around joints rather than muscle. These warrant backing off, adjusting your plan, or consulting a professional.
Hypertrophy research suggests sets taken close to muscular failure (about 1–3 reps left in the tank, often called RIR) are effective. You may or may not feel sore after such sets, but they send a clear signal for your muscles to adapt. Many people think ‘not sore’ means ‘didn’t work hard enough’, but if you reached your target RIR with good form across your planned sets, you likely provided sufficient stimulus.
Great for
Your ability to adapt from training depends heavily on sleep, adequate protein and calories, hydration, and stress management. Good recovery often means less lingering soreness even when training hard—this is a positive sign. Poor sleep or low protein can make you feel excessively sore from the same workout, without better results. Aim for around 1.6–2.2 g of protein per kg of body weight daily and 7–9 hours of sleep for most adults.

Good training should leave you feeling generally energetic, not constantly drained. If your sleep is stable, mood is decent, and you can hit planned workouts without dreading them, your stress/recovery balance is likely good. This often means less painful soreness even as you progress.
