You can’t completely eliminate muscle soreness after a tough workout, but you can significantly reduce how bad it gets. The soreness you feel 12 to 72 hours after exercise, known as delayed onset muscle soreness (DOMS), comes from microscopic structural damage to muscle fibers when they’re pushed beyond what they’re used to. The good news: nearly every factor that worsens that damage is something you can control before, during, or after your session.
Why Your Muscles Get Sore in the First Place
Muscle soreness isn’t caused by lactic acid buildup, despite what you may have heard. It’s a mechanical injury. When you load your muscles beyond their current structural capacity, especially during the lowering (eccentric) phase of a movement, the internal architecture of individual muscle fibers tears at an ultrastructural level. Think of it like stretching a rubber band past its limit: the tiny internal components that make muscles contract get pulled apart.
Once that damage occurs, your body launches a local inflammatory response. Protein breakdown, cellular cleanup processes, and inflammation markers all spike. Fluid leaks into the damaged tissue, causing swelling inside the muscle fibers themselves. This internal edema, combined with inflammatory signaling molecules sensitizing nearby nerve endings, is what makes your muscles feel tender, stiff, and painful the next day or two. The peak usually hits around 24 to 48 hours post-exercise, then gradually fades over three to five days as repair outpaces damage.
Control Your Training Load
The single most effective way to prevent excessive soreness is to manage how quickly you ramp up your workouts. Soreness is driven by novelty and intensity: doing movements your muscles aren’t adapted to, or doing far more volume than your body is ready for. A general guideline is to increase weight or total volume by no more than 10 percent per week. That applies to running mileage, lifting weight, number of sets, or any other measurable training variable.
This doesn’t mean you should avoid challenging workouts forever. It means you give your muscles time to adapt structurally before adding more stress. After a few exposures to the same type of exercise, your muscle fibers remodel and become more resistant to the same damage. This is called the repeated bout effect, and it’s one of the most powerful built-in protections your body has. The first time you do heavy lunges might leave you hobbling for three days. The third time, with the same weight, you’ll barely notice.
If you’re starting a new program or returning after a break, cut your planned volume roughly in half for the first week and build from there. Pay particular attention to exercises with a strong eccentric component: think downhill running, lowering phases of squats or deadlifts, and plyometrics. These generate the most micro-damage per repetition.
Warm Up With Movement, Not Just Stretching
A proper warm-up raises muscle temperature, increases blood flow, and improves the elasticity of connective tissue, all of which make fibers more resilient under load. Five to ten minutes of light aerobic activity (cycling, rowing, brisk walking) followed by dynamic movements that mimic your workout is more effective than static stretching alone. Static stretching before exercise has not been shown to reduce DOMS and may temporarily reduce force output.
Dynamic warm-ups work because they prepare the specific muscle groups you’re about to use by taking them through progressively larger ranges of motion under light load. Leg swings before running, arm circles before pressing, bodyweight squats before barbell squats. The goal is to rehearse the movement pattern while gradually increasing intensity.
Use Active Recovery After Hard Sessions
Light exercise the day after a hard workout can temporarily reduce soreness and may speed recovery. The key word is light. Research on active recovery suggests that moderate-intensity aerobic exercise (around 70 percent of your maximum heart rate reserve) is more effective at reducing DOMS than very low-intensity movement. For most people, that translates to a pace where you’re breathing noticeably harder but can still hold a conversation: a brisk bike ride, an easy swim, or a 20 to 30 minute walk with some hills.
Active recovery works partly by increasing blood flow to damaged tissues, which helps deliver nutrients and clear inflammatory byproducts. It won’t undo the structural damage, but it can reduce the stiffness and tenderness that make soreness feel worse than it needs to.
What You Eat and Drink Matters
Your body needs raw materials to repair damaged muscle fibers, and what you consume in the hours and days around hard training can influence how sore you get.
Protein Timing and Amount
Consuming protein within a few hours of exercise provides the amino acids your muscles need to begin repair. Aim for 20 to 40 grams of protein per meal, spread across three to four meals per day. The total daily amount matters more than obsessing over a post-workout window, but don’t leave a long gap after training either.
Anti-Inflammatory Foods
Omega-3 fatty acids, found in fatty fish, flaxseed, and fish oil supplements, have been shown to reduce markers of exercise-induced muscle damage. Studies suggest benefits increase with higher doses, up to about 6 grams per day, though most people will get meaningful effects from 2 to 3 grams daily. Consistent intake over several weeks matters more than taking a single dose after one workout.
Tart cherry juice is one of the more well-studied options. In the original landmark study, two 12-ounce servings per day (starting three days before exercise and continuing four days after) reduced pain and improved strength recovery. The benefits come from anthocyanins, the pigments that give cherries their deep red color, which act as natural anti-inflammatory compounds. Tart cherry concentrate, capsules, and other polyphenol-rich foods like blueberries and pomegranate follow similar principles.
Hydration
Dehydration can worsen soreness symptoms, though the relationship is more nuanced than “drink more water, hurt less.” Research from Cleary et al. found that DOMS was significantly worse when people were dehydrated and overheated before exercise. When core body temperature was brought back to normal before the workout, the dehydration effect on soreness largely disappeared. The practical takeaway: staying well-hydrated matters most when you’re exercising in heat or doing prolonged endurance work. Don’t ignore thirst, and replace electrolytes during sessions lasting longer than 60 minutes.
Cold Water Immersion After Exercise
Ice baths remain one of the most popular recovery tools, and the evidence supports their use for reducing soreness specifically. The recommended protocol is water between 11°C and 15°C (roughly 52°F to 59°F) for 11 to 15 minutes. Colder isn’t necessarily better. Studies testing water at 6°C versus 14°C both showed benefits, but the more moderate range is easier to tolerate and produces comparable results.
Cold water works by constricting blood vessels and reducing the inflammatory swelling inside damaged muscle fibers. It also has a mild numbing effect on nerve endings. One important caveat: if your primary goal is building muscle size and strength rather than just reducing soreness, regular cold water immersion may slightly blunt the adaptive signals that drive muscle growth. For competitive athletes managing soreness between events, it’s a solid tool. For someone focused on long-term strength gains, save it for particularly brutal sessions rather than making it a daily habit.
Sleep Is Non-Negotiable
Most muscle repair happens during deep sleep, when growth hormone release peaks and protein synthesis ramps up. Consistently getting less than seven hours reduces your body’s ability to recover from training and amplifies perceived soreness. You can’t supplement or ice-bath your way out of poor sleep. If you’re doing everything else right but still getting crushed by soreness, this is often the missing piece. Aim for seven to nine hours, keep your room cool, and try to maintain a consistent sleep schedule even on rest days.
Putting It All Together
Prevention works best as a layered strategy rather than a single silver bullet. The highest-impact actions, in rough order of importance: progress your training gradually (10 percent per week or less), warm up with dynamic movement before sessions, eat enough protein spread throughout the day, sleep seven-plus hours, and stay hydrated. Layer in tart cherry juice or omega-3s if soreness is a recurring problem. Use cold water immersion selectively after your hardest sessions. And on the day after a tough workout, move at a moderate pace for 20 to 30 minutes rather than spending the entire day on the couch.
Some soreness after new or intense exercise is normal and even expected. The goal isn’t to feel nothing. It’s to keep soreness at a level that doesn’t interfere with your next training session or your daily life.
