Muscle soreness is one of the most common deterrents to consistent training. After a tough session, many people face a genuine dilemma: push through the discomfort and risk worsening recovery, or rest and risk losing momentum. The evidence points toward a nuanced middle path that depends on what kind of soreness you are actually feeling.
Westcott (2012; PMID 22777332) reviewed the physiological basis of delayed onset muscle soreness (DOMS), confirming it as a normal consequence of resistance training, particularly when introducing novel exercises or increased volume. Importantly, DOMS does not indicate injury. It signals normal muscle repair, and understanding this distinction changes how you should respond to it. According to the ACSM guidelines (Garber et al., 2011; PMID 21694556), exercise programming should account for muscle soreness as a normal recovery response, not as a barrier to training but as a signal that guides intensity and volume on subsequent sessions.
This guide covers the science of DOMS, how to distinguish normal soreness from injury pain, when light training through soreness is safe and beneficial, and when rest is the wiser choice. It also includes practical recovery strategies that accelerate soreness resolution without compromising training consistency. Schoenfeld et al. (2017; PMID 27433992) add an important framing to the discussion: training volume is the primary driver of both muscle adaptation and DOMS, so the same variable you manage to accelerate progress also dictates how sore you get. The goal is intelligent adaptation, not toughness for its own sake.
Understanding Muscle Soreness
Muscle soreness after exercise is one of the most universal experiences in fitness, from first-time lifters to seasoned athletes. The key question is whether to push through the soreness and work out anyway, or rest until the discomfort subsides. The honest answer is that neither default is correct: the right response depends on the type and severity of soreness you are experiencing that day.
Normal muscle soreness is the outcome of a specific physiological process. According to Westcott (2012; PMID 22777332), resistance training consistently produces measurable muscle adaptation, and initial soreness decreases significantly after the first several sessions as muscles adapt to the training stimulus. This is the “repeated bout effect”: the same workout that left you barely able to walk down stairs in week one produces far less soreness by week four, even as the tissue is still adapting positively. The ACSM position stand (Garber et al., 2011; PMID 21694556) explicitly frames this pattern as normal and expected, not as a sign of insufficient stimulus.
Three practical implications follow. First, soreness is information, not a verdict. Mild to moderate soreness tells you the tissue is remodeling; severe soreness that persists past 72 hours tells you volume or novelty outpaced recovery. Second, soreness is not a performance metric. Schoenfeld et al. (2017; PMID 27433992) document that training volume, not soreness intensity, predicts hypertrophy outcomes across multi-week interventions. You can have a highly effective workout with minimal soreness, especially as training age increases. Third, understanding the difference between normal muscle soreness and pain that signals injury is essential for safe training decisions, and that distinction is the subject of a dedicated section below.
A useful working model: treat soreness like sleep debt. Mild accumulation is a feedback signal to modulate the next session, while severe accumulation is a stop sign that demands a genuine rest day. The Physical Activity Guidelines for Americans, 2nd edition (HHS/ODPHP, 2018) implicitly support this responsive approach by framing activity as a weekly dose rather than a fixed daily schedule, which leaves room to adjust based on recovery signals.
What Is DOMS?
The muscle soreness you feel one to three days after exercise has a specific name: delayed onset muscle soreness, or DOMS. This is a different sensation from the burning during exercise itself, which is caused by metabolic byproducts and typically disappears within minutes to hours after the session ends. According to the ACSM position stand (Garber et al., 2011; PMID 21694556), DOMS is a normal physiological response to unaccustomed exercise (particularly eccentric loading) and should not be conflated with injury.
DOMS has a predictable timeline. Soreness typically begins 12 to 24 hours after exercise, peaks around 24 to 72 hours post-workout, and gradually subsides over the following few days. The intensity depends heavily on training age, exercise novelty, and total volume. Westcott (2012; PMID 22777332) notes that novel exercises reliably produce more soreness than familiar ones, even at matched total work, which is why the first week of any new program is typically the sorest.
The underlying mechanism is microscopic damage to muscle fibers during exercise, particularly during eccentric (lengthening) contractions. When you lower a weight, run downhill, or perform the descent phase of a push-up, your muscles experience eccentric stress. This type of contraction causes more microscopic tears in muscle fibers compared to concentric (shortening) contractions at equivalent forces. Your body responds by initiating an inflammatory response to repair the damage, and it is this inflammatory response (not the damage itself) that produces the characteristic soreness and stiffness of DOMS.
Schoenfeld et al. (2017; PMID 27433992) add an important dose-response observation: the relationship between weekly resistance training volume and muscle adaptation is linear within normal ranges, but soreness rises disproportionately when volume jumps too fast. This is why experienced lifters can tolerate much higher weekly volumes without extreme soreness, while the same volume introduced suddenly to an intermediate trainee produces days of heavy DOMS. Schoenfeld et al. (2016; PMID 27102172) reinforce this in their frequency meta-analysis: distributing volume across more sessions produces less per-session damage and therefore less extreme DOMS, while still supporting the hypertrophy outcomes that matter.
Two practical consequences: introduce new exercises gradually and progress weekly volume at manageable increments. Doing so captures the adaptation signal without the debilitating soreness that disrupts subsequent sessions.
Why Do Some Workouts Cause More Soreness Than Others?
Some workouts leave you incredibly sore while others cause minimal discomfort, even if they felt equally challenging during the session. Several factors influence DOMS severity, and understanding them helps you predict and manage it. Schoenfeld et al. (2017; PMID 27433992) identified training volume as a primary driver of both adaptation and soreness: higher weekly volume is associated with greater muscle growth, but also greater initial soreness in untrained or detrained individuals.
Novel movements or exercises your body is not accustomed to cause more soreness than familiar ones. This is the “repeated bout effect” Westcott (2012; PMID 22777332) documents in detail: the same eccentric stimulus produces dramatically less soreness on the second and subsequent exposures because the muscle has already adapted structurally and protectively to that specific pattern. It is the main reason the first week of a new program feels brutal and weeks four through six feel almost unremarkable at the same loads.
Eccentric-heavy exercises cause more soreness than concentric-focused work. Downhill running, slow-tempo lowering of weights, negative-accentuated reps, and plyometric movements (which involve high eccentric forces on landing) all reliably produce more DOMS than their concentric-dominant equivalents. Training volume beyond your current tolerance predictably increases soreness. Schoenfeld et al. (2016; PMID 27102172) note that splitting weekly volume across more sessions reduces per-session damage, which is why a twice-weekly split of the same total work tends to produce less extreme DOMS than a single high-volume session.
Insufficient recovery between similar workouts prevents complete muscle repair, so the next session begins on partially damaged tissue and compounds the signal. The ACSM position stand (Garber et al., 2011; PMID 21694556) recommends 48 to 72 hours between intense sessions targeting the same muscle groups specifically for this reason. Genetics also play a meaningful role. Some people are simply more prone to DOMS than others at matched training stimuli, and this sensitivity does not correlate cleanly with how strong or fit they are.
Two more factors rarely get enough attention. Hydration status affects the inflammatory response to eccentric damage, with dehydration typically worsening perceived soreness. Sleep quality over the 48 hours following the session affects repair speed, which partly determines how long DOMS lingers. Westcott (2012; PMID 22777332) highlights both as underestimated recovery variables in adult populations. The Physical Activity Guidelines for Americans, 2nd edition (HHS/ODPHP, 2018) reinforce this broader framing: activity outcomes depend on recovery support, not just session design.
Soreness vs Injury: How to Tell the Difference
The most important distinction in this entire article is whether what you are feeling is normal muscle soreness or pain from an actual injury. Training through DOMS is often fine. Exercising with an injury can convert a minor issue into a serious problem requiring weeks off. The ACSM guidelines (Garber et al., 2011; PMID 21694556) recommend stopping exercise and seeking evaluation when pain is sharp, localized, or worsening, distinguishing these signals clearly from normal DOMS discomfort that improves with warm-up.
Normal muscle soreness from DOMS has specific characteristics that make it recognizable. It feels like a dull, widespread ache throughout the muscle, not a sharp point. It affects both sides of the body relatively symmetrically when both sides were trained equivalently. The discomfort improves with warm-up and movement, often fading noticeably after 10 minutes of easy activity. You maintain full range of motion, though it may feel stiff initially. The pain gradually decreases over 3 to 5 days and follows the predictable 24 to 72 hour peak timeline. There is no visible swelling, bruising, or deformity.
Injury pain presents differently in almost every respect. It feels sharp or stabbing rather than dull and achy. It is often localized to a specific point or structure (a tendon, joint line, or muscle belly insertion) rather than distributed across the whole muscle. The pain worsens with activity and does not improve with warm-up; in fact, it often becomes sharper as you load the tissue. You experience reduced range of motion or inability to perform certain movements cleanly. The pain persists beyond 5 to 7 days without improvement, or it improves only briefly and returns when you reload. You may notice swelling, bruising, or visible changes, and occasionally a popping or tearing sensation at the moment of injury.
If pain has characteristics of injury rather than normal soreness, rest and seek medical evaluation rather than training through it. Westcott (2012; PMID 22777332) is explicit that training through sharp, localized pain is the single most common way people convert minor tissue issues into weeks of forced inactivity. Schoenfeld et al. (2016; PMID 27102172) note that injury-related training interruptions are a leading cause of hypertrophy program failure over longer time horizons, which makes early identification of injury pain a direct contributor to long-term progress.
A practical decision rule: if pain is localized, sharp, and fails to improve with warm-up, treat it as potential injury and stop. If pain is diffuse, dull, symmetric, and eases with movement, treat it as DOMS and proceed with reduced intensity as outlined below.
The Science: Should You Train With Sore Muscles?
The evidence on training with muscle soreness challenges both extremes: the old “no pain, no gain” attitude that pushes through everything, and the idea that you must be completely pain-free before training again. The correct answer lives between those two positions and depends on the severity of soreness and the type of training planned.
Light to moderate exercise can actually reduce the perception of muscle soreness and may speed recovery. This happens because movement increases blood flow to affected muscles, delivering nutrients and oxygen while clearing metabolic waste products. Westcott (2012; PMID 22777332) noted that active recovery strategies, including light exercise targeting sore muscles, are associated with faster return to full training capacity compared to passive rest alone. The effect is measurable in the session itself: many people report that their DOMS decreases noticeably during a gentle walk or easy cycling session and returns to baseline within an hour afterward.
High-intensity training on muscles experiencing significant DOMS, however, tends to be counterproductive. When muscles are damaged and inflamed, intense exercise causes additional damage without allowing the initial repairs to complete. Schoenfeld et al. (2017; PMID 27433992) document this pattern in their dose-response work on resistance training volume: once weekly volume exceeds the tissue’s recovery capacity, additional work produces smaller hypertrophy gains and greater injury risk rather than better outcomes. The ACSM position stand (Garber et al., 2011; PMID 21694556) aligns with this by recommending 48 to 72 hours between intense sessions targeting the same muscle groups.
The optimal approach is active recovery: performing lighter exercise that engages the sore muscles without stressing them intensely. This promotes recovery while maintaining your exercise habit and routine. Schoenfeld et al. (2016; PMID 27102172) note in their frequency meta-analysis that training each muscle group twice per week produced greater hypertrophy than once-per-week training, which implicitly supports training through mild soreness at reduced intensity rather than waiting for full pain-free status before the next session.
A practical framework: if soreness is mild (barely noticeable except when you stretch the muscle), train normally. If soreness is moderate (stiff but you have full range of motion), train at 70 percent of normal intensity. If soreness is severe (painful to initiate movement, noticeably limiting range of motion, or interfering with daily activities like walking or reaching), train a different muscle group or take an active recovery day. The ACSM guidelines, Westcott (2012; PMID 22777332), and the Schoenfeld et al. frequency work all support this graded response over either extreme.
When You Can Safely Work Out With Sore Muscles
If your muscle soreness is mild to moderate and has the characteristics of DOMS rather than injury, you can generally exercise safely with some modifications. According to the ACSM position stand (Garber et al., 2011; PMID 21694556), light-to-moderate intensity activity involving sore muscle groups is generally safe and often beneficial. The key principle is reducing intensity rather than eliminating activity.
Light cardiovascular exercise like walking, easy cycling, or swimming at a conversational pace is almost always safe and beneficial when dealing with muscle soreness. These activities increase blood flow without stressing the sore muscles intensely, and Westcott (2012; PMID 22777332) cites this kind of low-intensity movement as one of the most consistently effective recovery interventions in resistance-trained adults. The effect is usually felt within the session: gentle activity often produces a measurable reduction in perceived soreness by the time you finish.
Working different muscle groups is another smart strategy. If legs are sore from squats, you can train the upper body. If chest and arms are sore from pressing work, you can perform lower body exercises. This approach maintains training frequency while giving sore muscles extra recovery time, and it aligns directly with the twice-weekly split pattern Schoenfeld et al. (2016; PMID 27102172) found most supported in the hypertrophy literature. A simple upper-lower split gives each muscle group 48 to 72 hours between sessions by design, which is exactly the recovery window DOMS typically needs.
Reduced-intensity training on sore muscles can also work well. At moderate soreness levels, performing the same exercises at 50 to 70 percent of normal intensity maintains the movement pattern and neural rehearsal without driving additional damage. Focus on movement quality and controlled range of motion rather than pushing for personal bests. Schoenfeld et al. (2017; PMID 27433992) note that maintained frequency with reduced per-session volume tends to produce better outcomes than skipped sessions followed by catch-up volume.
Dynamic stretching and mobility work help reduce stiffness and improve range of motion without causing additional muscle damage. Gentle yoga or mobility routines can be particularly helpful on days when soreness is present but you still want structured movement. The Physical Activity Guidelines for Americans, 2nd edition (HHS/ODPHP, 2018) and WHO guidelines support this kind of light daily activity as part of sustainable weekly patterns, and the ACSM position stand explicitly recommends flexibility training two to three days per week regardless of current soreness status.
A practical heuristic: if a warm-up noticeably reduces the soreness within 5 to 10 minutes, you can proceed with reduced-intensity training on that muscle group. If the warm-up does not help or makes things worse, train a different muscle group or switch to active recovery.
When You Should Rest Instead of Training
Despite the benefits of active recovery, there are situations when complete rest is the better choice. Knowing when to back off is just as important as knowing when to push through. Schoenfeld et al. (2016; PMID 27102172) found that training frequency recommendations must account for individual recovery capacity, and insufficient recovery between sessions reduces hypertrophy outcomes rather than enhancing them. Overshooting on a bad day can cost more per week than the session would have added per year.
If soreness is severe enough to significantly limit range of motion or make daily activities like sitting down, climbing stairs, or reaching overhead difficult, take a complete rest day. This level of soreness indicates substantial muscle damage that needs more time to repair, and training through it typically extends the recovery window rather than shortening it. Westcott (2012; PMID 22777332) documents this pattern in resistance-trained adults: severe DOMS that is pushed through regularly correlates with higher injury rates and more frequent plateau periods.
When pain rather than soreness is present (sharp, localized discomfort that worsens with movement or that triggers at a specific range rather than generally), rest and potentially seek medical evaluation. The ACSM position stand (Garber et al., 2011; PMID 21694556) treats these as stop-work criteria specifically because continuing to load injured tissue reliably escalates minor issues into longer layoffs. If you are experiencing other signs of overtraining alongside the soreness (elevated resting heart rate, difficulty sleeping, persistent fatigue, loss of appetite, or declining session performance), your body needs rest, not more exercise. Schoenfeld et al. (2017; PMID 27433992) note that overtraining patterns typically show up as multiple simultaneous signals rather than single dramatic symptoms, so a morning that combines heavy DOMS with poor sleep and low motivation is a clear call for rest.
If soreness is not improving after 5 to 7 days, or if it is getting worse instead of better, something is wrong. This could indicate an injury masquerading as DOMS, or it might suggest insufficient recovery resources (sleep, nutrition, hydration) rather than just a tough session. The intervention is typically not more or different training but a focused look at sleep consistency, protein intake, and overall life stress.
A useful decision rule for severe soreness days: default to one of three options in order of severity. First, active recovery only (walking, easy cycling, light mobility). Second, train a completely different muscle group at normal intensity. Third, complete rest with focus on sleep and nutrition. Picking the right one requires honesty about which muscles are actually sore and how severe the soreness is. The Physical Activity Guidelines for Americans, 2nd edition (HHS/ODPHP, 2018) and WHO recommendations both explicitly support this kind of responsive flexibility.
The Role of Active Recovery
Active recovery has become a popular concept in fitness, but it means something specific: low-intensity movement performed on rest days or following intense workouts to promote blood flow and recovery without creating additional training stress. The ACSM guidelines (Garber et al., 2011; PMID 21694556) support active recovery as part of a structured exercise program, noting that light activity on rest days maintains cardiovascular efficiency and aids metabolic waste clearance from previously trained muscles.
Effective active recovery activities include walking at an easy pace for 20 to 30 minutes, cycling at low resistance and conversational effort, swimming with relaxed strokes, gentle yoga focused on breathing and mobility, dynamic stretching and mobility drills taking joints through full ranges without load, and foam rolling or self-massage techniques targeting the areas of DOMS directly. Westcott (2012; PMID 22777332) specifically identifies this kind of low-load movement as supportive of recovery in resistance-trained adults, and the benefits are measurable both subjectively (reduced perceived soreness, better mood, improved sleep that night) and objectively (restored session output the following day).
The key principle of active recovery is that it should feel easy. If you are breathing hard or feeling challenged, the intensity is too high for recovery purposes, and you are essentially adding a low-volume workout rather than supporting recovery. A simple benchmark: you should be able to hold a full conversation in complete sentences throughout the session. If you cannot, reduce intensity or duration.
Active recovery serves three distinct functions. It accelerates recovery from the previous hard session by increasing blood flow to sore muscles without causing additional damage. Schoenfeld et al. (2017; PMID 27433992) document that volume distributed with adequate recovery between sessions produces better hypertrophy outcomes than concentrated volume with insufficient recovery, and active recovery supports that between-session recovery directly. It maintains the exercise habit on days that would otherwise be sedentary, which matters disproportionately for long-term adherence, particularly for adults juggling work and family demands.
It provides low-stress aerobic exposure that contributes to weekly aerobic totals recommended by the Physical Activity Guidelines for Americans, 2nd edition (HHS/ODPHP, 2018) and WHO guidelines without compounding training stress. A 30-minute walk on an active recovery day can account for a meaningful portion of the 150-minute weekly moderate-intensity target while leaving hard-session days for the high-intensity work. The ACSM position stand (Garber et al., 2011; PMID 21694556) explicitly supports this division of weekly work between high and low intensity days as sustainable programming.
A practical structure: schedule at least one active recovery day immediately after your hardest training day, not several days later when muscles have already begun resolving on their own.
Strategies to Reduce Muscle Soreness
While some soreness is normal and indicates muscle challenge, excessive soreness interferes with training consistency. Several strategies help minimize soreness and speed recovery. Westcott (2012; PMID 22777332) identified gradual volume progression as the single most effective preventive strategy, noting that most severe DOMS cases in research studies resulted from introducing high-volume novel stimuli without adequate adaptation periods.
Gradual progression is the most powerful prevention lever. When starting a new program or increasing training volume, make small increments rather than large jumps. The “ten percent rule” (increasing weekly volume by no more than ten percent) helps prevent the excessive soreness that derails the first weeks of new programs. Schoenfeld et al. (2017; PMID 27433992) show that the dose-response relationship between weekly volume and hypertrophy is roughly linear within normal ranges, so modest, steady progression captures almost all the benefit while avoiding the soreness spikes that come from volume jumps.
Proper warm-up before exercise prepares muscles for work and likely reduces subsequent soreness. A good warm-up includes 5 to 10 minutes of light cardio to raise muscle temperature and blood flow, followed by dynamic stretching and movement patterns similar to your workout. The ACSM position stand (Garber et al., 2011; PMID 21694556) specifically recommends this warm-up structure as standard for injury prevention, and its effects on subsequent DOMS appear to be a useful side benefit.
Post-workout cool-down with light activity and gentle stretching helps clear metabolic waste products and may reduce soreness severity on subsequent days. Adequate protein intake (typically 0.7 to 1 gram per pound of body weight daily) provides the amino acids required for muscle repair, and Westcott (2012; PMID 22777332) identifies protein sufficiency as one of the most frequently underestimated recovery variables in adult populations. Well-maintained hydration supports the inflammatory response and protein synthesis that drive muscle repair; even mild dehydration prolongs DOMS.
Quality sleep is when most muscle repair occurs. Consistently getting 7 to 9 hours per night is central to managing soreness, and Schoenfeld et al. (2016; PMID 27102172) note that the frequency-hypertrophy relationship in their meta-analysis assumed adequate sleep, with outcomes degrading predictably under chronic restriction. Some evidence suggests cold water immersion immediately post-exercise and heat therapy applied 48 hours later may help reduce soreness, though individual responses vary widely and neither intervention is as reliable as the fundamentals of gradual progression, adequate sleep, sufficient protein, and proper hydration.
A practical priority order when soreness is repeatedly excessive: first check sleep duration, then protein intake, then volume progression rate. Most chronic DOMS problems resolve at one of those first three levels, before any specific recovery intervention.
Programming Around Soreness
Smart training programs account for muscle soreness by structuring workouts to allow adequate recovery while maintaining training frequency. Schoenfeld et al. (2017; PMID 27433992) found that optimal weekly training volume for hypertrophy is best distributed across multiple sessions, meaning program design that anticipates recovery (including soreness management) is essential for maximizing long-term results rather than a nice-to-have.
Split routines that work different muscle groups on different days are the core technique. An upper-lower split allows you to train four days per week while giving each muscle group 48 to 72 hours to recover between sessions targeting it directly, which matches the physiological recovery window for DOMS almost exactly. A push-pull-legs split across six days gives each muscle group two sessions per week with the same recovery window. Schoenfeld et al. (2016; PMID 27102172) explicitly support these structures in their frequency meta-analysis, finding that twice-weekly frequency outperforms once-weekly at matched total volume.
Undulating periodization, which varies intensity across the week, allows more frequent training of the same muscles by alternating heavy, moderate, and light sessions. A typical pattern is one heavy day (high intensity, low volume), one moderate day (moderate intensity, moderate volume), and one light day (low intensity, higher volume). This structure allows you to work similar movement patterns multiple times per week without constantly operating at the intensity that produces the most DOMS.
Deload weeks, where you intentionally reduce training volume and intensity every 4 to 6 weeks, give the body a chance to fully recover and consolidate adaptations from the preceding block. The ACSM position stand (Garber et al., 2011; PMID 21694556) recommends planned lighter weeks as part of periodized programming specifically to prevent the accumulation of fatigue and excessive chronic soreness that would otherwise compound across training blocks. Westcott (2012; PMID 22777332) documents that periodization structures built around regular deload weeks consistently outperform constant-intensity programs over cycles of six months or more.
Exercise ordering within a session also matters. Pairing antagonist muscle groups (push-pull, squat-pull, chest-back) during the same session distributes stress more evenly than stacking all the volume on a single muscle group, and it tends to produce less extreme next-day soreness at matched total work. Single-joint isolation work placed at the end of the session (rather than at the start) typically produces less severe DOMS than beginning a session with it, because the target muscle is not yet fully fatigued.
A practical template for intermediate trainees: upper-lower split four days per week with antagonist pairing, undulating intensity (one heavy upper, one moderate upper, one heavy lower, one moderate lower), and a deload week every five weeks. This structure keeps DOMS manageable while supporting the twice-weekly frequency the hypertrophy literature supports.
Common Training With Sore Muscles Mistakes to Avoid
Several common mistakes worsen soreness or convert it into injury. Recognizing these patterns before they happen gives you a significant training advantage. According to the ACSM position stand (Garber et al., 2011; PMID 21694556), most exercise-related setbacks are preventable through intelligent programming and early response to warning signals.
Ignoring pain signals in pursuit of training goals is the most common and costly mistake. There is a clear difference between DOMS discomfort and sharp, localized injury pain, and learning to distinguish between them is essential for long-term training success. Westcott (2012; PMID 22777332) is explicit that training through sharp pain is the primary way minor tissue issues become multi-week layoffs. The correct response to sharp pain is stopping that exercise, substituting a pain-free alternative, and evaluating further if pain persists.
Maintaining the same training intensity while experiencing significant soreness usually backfires. Performance drops, form degrades, and the added damage from a high-intensity session on already-damaged tissue produces worse outcomes than either full rest or reduced-intensity training would have. Schoenfeld et al. (2017; PMID 27433992) document this pattern in volume-dose research: once weekly volume exceeds recovery capacity, additional work produces diminishing then negative returns rather than more gains.
Neglecting warm-up and cool-down because you are sore and want to shorten the workout removes two of the simplest tools for managing DOMS. A proper warm-up often reduces perceived soreness within 5 to 10 minutes, and a short cool-down supports recovery for the following day. Cutting them to save time on a sore day typically makes the next day worse rather than better.
Taking anti-inflammatory medications regularly to mask soreness may interfere with the muscle adaptation process. Research suggests that chronic NSAID use can blunt the inflammatory signaling that drives muscle protein synthesis, potentially reducing hypertrophy gains over time. Occasional use for acute issues is typically fine, but daily use as a soreness management strategy is not supported by the evidence and may undermine the training you are doing. Westcott (2012; PMID 22777332) flags this specifically in resistance-trained adults as a quiet saboteur of long-term progress.
Other common mistakes include training through severe DOMS that limits range of motion (which usually reduces form quality and raises injury risk), failing to adjust program volume after extended layoffs (which reliably triggers the “first week back” DOMS flare), and using soreness as a proxy for workout quality (which Schoenfeld et al. (2016; PMID 27102172) explicitly contradict, since hypertrophy outcomes depend on volume and frequency rather than soreness intensity). The Physical Activity Guidelines for Americans, 2nd edition (HHS/ODPHP, 2018) reinforce the broader point: consistency and appropriate dose matter more than any single intense session.
The Bottom Line on Training With Sore Muscles
Can you work out when muscles are sore? In most cases, yes, but with intelligent modifications. Light to moderate exercise, active recovery, and training different muscle groups are all safe and often beneficial approaches when dealing with normal DOMS. Severe soreness, pain with characteristics of injury, or other signs of overtraining warrant additional rest, and pushing through them typically extends the recovery window rather than shortening it.
Learning to listen to your body and distinguish between normal training soreness and pain that signals a problem is one of the most valuable skills you can develop in fitness. The research base is consistent on this point. The ACSM position stand (Garber et al., 2011; PMID 21694556), Westcott (2012; PMID 22777332), Schoenfeld et al. (2016; PMID 27102172), and Schoenfeld et al. (2017; PMID 27433992) all converge on the same practical framework: DOMS is a normal consequence of training that requires modulation rather than elimination, and responsive programming that adjusts to soreness signals produces better long-term outcomes than either dogmatic rest or dogmatic intensity.
Soreness is not a requirement for progress. You can have highly effective workouts without experiencing significant DOMS, particularly as training age increases and the repeated bout effect reduces per-session soreness on familiar movements. Schoenfeld et al. (2017; PMID 27433992) document that hypertrophy outcomes track weekly volume rather than soreness intensity, which means minimal soreness in a structured program is compatible with strong ongoing adaptation. As you become more experienced and your body adapts to regular training, you will likely experience less soreness even as your fitness continues to improve, which is the pattern the Physical Activity Guidelines for Americans, 2nd edition (HHS/ODPHP, 2018) and WHO recommendations implicitly assume for long-term exercisers.
