Muscle soreness after exercise typically peaks between 24 and 48 hours, then fades by 72 hours. The best things you can do are stay lightly active, use temperature therapy strategically, foam roll, and support recovery with adequate protein and hydration. Most soreness resolves on its own, but how you spend those few days can meaningfully reduce the discomfort and get you moving normally again faster.
Why Your Muscles Feel Sore
When you push your muscles harder than they’re used to, especially during movements where muscles lengthen under load (think: lowering yourself into a squat, running downhill, or the lowering phase of a bicep curl), the internal fibers get stretched while they’re trying to contract. This creates microscopic structural disruption in the muscle tissue.
Your body responds with inflammation: swelling, increased tension, reduced range of motion, and that familiar deep ache. The soreness itself comes from inflammatory chemicals sensitizing your nerve endings, which is why even light pressure or simple movements can feel tender. This process is called delayed onset muscle soreness, or DOMS, and it’s a normal part of adaptation. Your muscles rebuild stronger afterward.
When Soreness Peaks and How Long It Lasts
Soreness is usually low right after exercise. It builds over the next day and typically hits its worst point around 36 to 48 hours later, then drops off by 72 hours. About 45% of people in one study experienced their peak soreness between 36 and 48 hours after a stepping exercise. Running is a notable exception: soreness from long-distance running tends to peak earlier, often at the first check-in after the event rather than following the classic delayed curve.
If your soreness follows this general arc, you’re dealing with normal DOMS. If it’s still intensifying after three or four days, or if you notice other symptoms (more on that below), something else may be going on.
Keep Moving With Light Activity
The single most effective thing you can do for sore muscles is gentle movement. A large meta-analysis of recovery techniques found that active recovery produced a meaningful reduction in soreness, outperforming several other popular methods. The mechanism is straightforward: light activity increases blood flow through muscle tissue, which helps clear inflammatory byproducts and reduces fluid buildup that contributes to stiffness and pain.
This doesn’t mean repeating your hard workout. It means easy walking, gentle cycling, swimming at a relaxed pace, or light yoga. The goal is circulation, not exertion. Sitting still all day, while tempting, generally leaves you feeling stiffer and more uncomfortable than staying gently active.
Foam Roll for 20 Minutes
Foam rolling is one of the more accessible tools for reducing soreness at home. A study on DOMS recovery found that rolling each muscle group for 45 seconds, resting 15 seconds, then repeating on the other side produced meaningful relief. The total session lasted 20 minutes (15 minutes of actual rolling, 5 minutes of rest between sets), covering the quads, inner thighs, hamstrings, outer thighs, and glutes in sequence.
Three of these 20-minute sessions, done immediately after exercise and then every 24 hours, substantially reduced muscle tenderness and helped restore normal movement patterns. You don’t need a fancy roller. A firm, high-density foam roller works well. Roll slowly, pause on tender spots, and breathe through the discomfort rather than grinding aggressively into the tissue.
Use Cold First, Then Switch to Heat
Temperature therapy works, but timing matters. In the first 24 to 48 hours, when inflammation is at its highest, cold is your better option. Cold constricts blood vessels, limits swelling, and numbs pain signals. An ice pack wrapped in a towel, a cold bath, or even a bag of frozen vegetables applied for up to 20 minutes at a time can help. Don’t apply ice directly to skin, and keep sessions under 20 minutes.
Once the initial inflammatory wave subsides (typically after 48 hours), heat becomes more useful. Warmth increases blood flow, relaxes tight muscles, and improves range of motion in stiff joints. A warm bath, heating pad, or hot water bottle for up to 20 minutes can loosen things up. Applying heat too early, when inflammation is still high, can actually make things feel worse by increasing swelling.
Support Recovery With Protein
Your muscles need raw materials to repair. The current evidence points to a daily protein intake of at least 1.6 grams per kilogram of body weight to maximize muscle recovery and growth. For a 70-kilogram (154-pound) person, that’s roughly 112 grams of protein per day. The upper end of the effective range is about 2.2 grams per kilogram, or around 154 grams daily for that same person.
Spreading this across at least four meals works better than loading it into one or two sittings. That works out to roughly 0.4 to 0.55 grams per kilogram per meal, or about 28 to 39 grams per meal for a 70-kilogram person. Think a chicken breast, a cup of Greek yogurt, a few eggs, or a protein shake at each meal. This isn’t just for bodybuilders. Anyone dealing with exercise-induced soreness benefits from giving their muscles enough protein to work with during the repair process.
Tart Cherry Juice as a Recovery Drink
Tart cherry juice has more research behind it than most recovery supplements. The key finding: it works best when you start drinking it several days before a hard workout, not after. Studies consistently show that muscle function recovers faster when cherry juice is consumed for about four days prior to the exercise that causes damage. Starting it on the day of exercise or afterward doesn’t show the same benefit.
The effective dose is two servings per day, each made from roughly 50 to 60 Montmorency tart cherries. In practical terms, that’s two 8-ounce glasses of juice made from whole frozen cherries, or two 30-milliliter (1-ounce) servings if you’re using a concentrated form. If you know a particularly demanding workout, race, or hike is coming up, starting cherry juice four to seven days beforehand is worth trying.
Magnesium and Muscle Relaxation
Magnesium plays a direct role in muscle relaxation and has both analgesic and vasodilator properties. It can help relieve soreness from exercise-induced muscle damage and reduce lactate levels. The recommended daily intake for adults is 410 to 420 milligrams for men and 320 to 360 milligrams for women. Active individuals may benefit from 10 to 20% above these levels, taken about two hours before exercise.
One important caveat: supplementing magnesium when your levels are already normal doesn’t appear to boost performance or further improve neuromuscular function. It’s most helpful if your intake has been low, which is common since many people fall short of recommended levels through diet alone. Magnesium-rich foods include spinach, pumpkin seeds, almonds, black beans, and dark chocolate. If you supplement, forms like magnesium glycinate tend to be better absorbed and gentler on the stomach than magnesium oxide.
Over-the-Counter Pain Relievers
Anti-inflammatory medications like ibuprofen are a common go-to for soreness, and the news here is more reassuring than the internet often suggests. While older studies using very high doses showed impaired muscle recovery, research using normal, pharmacologically relevant doses of ibuprofen found no negative effect on muscle mass or fiber regeneration. There were even signs of transiently improved growth signaling and reduced inflammatory markers. In one study of older adults, 12 weeks of resistance training combined with daily ibuprofen actually produced larger gains in muscle mass and strength than training alone.
Standard doses are fine for managing soreness when you need relief. That said, ibuprofen treats the symptom, not the cause. It won’t speed up the actual repair process, and relying on it to push through pain that’s telling you to rest can lead to real injury.
Red Flags That Aren’t Normal Soreness
Most post-exercise soreness is harmless, but rhabdomyolysis, a condition where muscle fibers break down severely enough to release their contents into the bloodstream, can look like extreme DOMS in its early stages. The CDC identifies three key warning signs: muscle pain that is more severe than expected, dark tea- or cola-colored urine, and unusual weakness or fatigue where you can’t complete physical tasks you’d normally handle. If you notice any of these, especially dark urine, seek medical attention immediately. Rhabdomyolysis is rare but can damage the kidneys if untreated.
