How to Help With Muscle Soreness After a Workout

Muscle soreness after a tough workout typically peaks between 48 and 72 hours, then fades on its own within about five days. You can speed that process along with a combination of movement, temperature therapy, nutrition, and hands-on recovery tools. The key principle behind most of these strategies is the same: get more blood flowing to the damaged tissue so your body can repair it faster.

Why Your Muscles Get Sore in the First Place

Delayed onset muscle soreness, or DOMS, usually shows up after exercise that involves lengthening contractions, like lowering a heavy weight, running downhill, or the “down” phase of a squat. The first symptoms appear 6 to 12 hours after the workout and build steadily from there. That 48-to-72-hour peak is why the second or third day after a hard session often feels worse than the first.

The traditional explanation is that tiny tears in muscle fibers trigger an inflammatory response, and that inflammation causes pain. The reality is more nuanced. Research has identified at least two nerve-signaling pathways that ramp up pain sensitivity in the muscle tissue after eccentric exercise, and this heightened sensitivity can occur even without visible damage or inflammation under a microscope. In practical terms, your muscles become temporarily more sensitive to pressure and movement, which is why even sitting down or walking stairs can feel surprisingly painful after a leg workout.

Keep Moving With Light Activity

The instinct to rest completely when you’re sore is understandable, but gentle movement is one of the most effective things you can do. Active recovery works because muscles and joints recover faster with increased circulation. Fresh blood delivers nutrients and warmth that support repair, while flushing out the metabolic byproducts of muscle breakdown.

The goal is any physical activity that increases circulation without adding muscular challenge. A walk, a light bike ride, an easy swim, or even tossing a ball around all qualify. Mobility exercises that move your joints through their full range of motion are also useful because they pump blood through the surrounding muscles without overloading any of them. The key distinction: you’re not trying to get a workout in. You’re trying to move enough to get blood flowing.

Cold Water Immersion Works Best at Moderate Temperatures

Cold water immersion (ice baths, cold plunges) has solid evidence behind it for reducing soreness, but the dose matters. A large network meta-analysis published in Frontiers in Physiology found that soaking for 10 to 15 minutes in water between 11°C and 15°C (roughly 52°F to 59°F) was the most effective protocol for reducing DOMS, with an 84.3% probability of being the best intervention tested. Colder water in that same 10-to-15-minute range also worked, but the moderately cold option ranked higher.

If you don’t have access to a cold plunge, a cold bath with ice added to bring the temperature into that range works fine. Shorter soaks or warmer water showed less benefit.

When to Use Heat Instead

Heat therapy is better suited for muscle stiffness and tightness. It relaxes muscle spasms and reduces joint stiffness, making it useful when your soreness has you feeling locked up. A warm bath, heating pad, or hot pack applied for 15 to 20 minutes can loosen things up and make movement more comfortable.

One important timing note from Johns Hopkins Medicine: avoid heat for the first 48 hours after an acute injury. For general post-workout soreness, heat tends to be most helpful once you’re past the initial inflammatory phase and dealing more with stiffness and reduced range of motion. Many people find that cold works best in the first day or two, and heat feels better from day two onward.

Foam Rolling: Three Minutes Is Enough

Foam rolling is one of the easiest recovery tools to use at home, and you don’t need to spend long on it. A study from James Madison University compared 3 minutes of total foam rolling (1 minute per muscle region) to 9 minutes of total rolling and found no difference in soreness reduction between the two. Both foam rolling groups had significantly lower soreness at 48 and 72 hours compared to doing nothing, and neither protocol impaired muscle function.

So spending one minute rolling each sore area is a reasonable target. You can do this daily while you’re recovering. Self-massage works on the same principle: compressing the tissue squeezes out fluid carrying waste products, and releasing the pressure lets fresh, nutrient-rich blood flow in.

Protein Intake Matters More Than Timing

Your muscles need protein to rebuild, and getting enough total protein throughout the day is more important than obsessing over a post-workout window. Sports nutrition experts generally recommend 1.6 to 2.2 grams of protein per kilogram of body weight per day to maximize muscle repair and growth. For a 70 kg (154 lb) person, that’s roughly 112 to 154 grams daily.

One useful benchmark: your body needs about 3 grams of leucine (an amino acid that signals muscle repair) to shift from breaking down muscle protein to building it back up. You’ll hit that threshold with roughly 30 grams of high-quality protein per meal. Chicken, fish, eggs, Greek yogurt, and whey protein all deliver leucine efficiently. Spreading your protein across meals rather than loading it all into one sitting gives your muscles more consistent raw material to work with.

Supplements That May Help

Tart cherry juice contains compounds that reduce swelling and act as antioxidants. The typical dose studied is 240 to 480 mL (about 8 to 16 ounces) per day. Some people drink it before and after heavy training sessions to blunt soreness.

Magnesium is worth considering if your intake is low, which is common in active people who sweat heavily. The most effective dose for muscle recovery in research is 300 to 500 milligrams of elemental magnesium per day, and doses below 250 mg may not do much unless you’re already deficient. The form you choose matters because absorption varies widely. Magnesium glycinate is well-absorbed and gentle on the stomach, with the added benefit of a calming effect that can improve sleep (which itself aids recovery). Magnesium malate supports cellular energy production and is often recommended for people with high training loads. Magnesium citrate is affordable and highly bioavailable, though it can cause loose stools at higher doses. All three of these are better absorbed than magnesium oxide or sulfate.

Compression Garments Need Longer Wear Times

Compression sleeves and tights are popular recovery tools, but the evidence suggests you need to wear them for a long time to see benefits. One study found that 12 hours of compression was not enough to improve recovery in a damaged upper arm, while other research reported positive results with wear times of 72 hours or more. If you’re going to use compression for recovery, plan on wearing the garment for several days rather than just tossing it on for a few hours after your workout.

Red Flags That Aren’t Normal Soreness

Typical DOMS is uncomfortable but not dangerous. It peaks around day two or three and gradually improves. There is, however, a serious condition called rhabdomyolysis where muscle tissue breaks down rapidly and releases proteins into the bloodstream that can damage the kidneys. According to the CDC, the warning signs include muscle pain that is more severe than you’d expect from the workout you did, dark urine that looks like tea or cola, and unusual weakness or fatigue where you can’t complete tasks you’d normally handle easily.

Symptoms of rhabdomyolysis can take hours or even several days to appear after the triggering exercise, which means the timing alone can’t help you distinguish it from DOMS. The only definitive test is a blood draw checking for a muscle protein called creatine kinase. Urine tests are unreliable because the relevant protein clears the body quickly. If your soreness feels disproportionate to what you did, or if your urine changes color, those are reasons to get evaluated promptly.
