Sore muscles after exercise typically peak between 24 and 72 hours after your workout, and several practical strategies can speed your recovery. The soreness happens because intense or unfamiliar movement creates microscopic damage in muscle fibers, triggering an inflammatory response that causes swelling and pain. This process, known as delayed onset muscle soreness (DOMS), is a normal part of how muscles rebuild stronger. Here’s what actually works to manage it.
Why Your Muscles Get Sore
When you push your muscles harder than they’re used to, especially during movements where muscles lengthen under load (like lowering a heavy weight, running downhill, or the “down” phase of a squat), the tiny contractile units inside muscle fibers get disrupted. This triggers your immune system to send inflammatory cells to the damaged area. Those cells release compounds that attract fluid into the tissue, causing the swelling, stiffness, and tenderness you feel the next day or two.
The pain usually doesn’t show up right away. It creeps in around 24 hours post-exercise and hits its worst point around 72 hours. After that, it gradually fades as your body completes the repair process. This timeline is worth knowing because it affects which recovery strategies work best at each stage.
Keep Moving With Light Activity
One of the most effective things you can do for sore muscles is also the simplest: keep moving. Light activity like walking, easy cycling, swimming, or gentle yoga increases blood flow to your muscles, which flushes out the cellular byproducts of exercise and helps your muscles return to their normal state faster. This approach, called active recovery, consistently outperforms complete rest for reducing soreness.
The key word is “light.” You’re not trying to get another workout in. Think 30 to 50 percent of your normal effort. A 20-minute walk, a slow bike ride, or some easy laps in the pool are all you need. The goal is circulation, not exertion.
When to Use Ice vs. Heat
Both ice and heat can help with sore muscles, but timing matters. In the first 24 to 48 hours, when inflammation is at its highest, cold therapy is more useful. Applying an ice pack for 15 to 20 minutes helps limit swelling and numbs pain. Heat applied too early can actually make things feel worse by increasing blood flow to already-inflamed tissue.
Once the initial inflammation settles down, usually after the first couple of days, switching to heat works well. A warm bath, heating pad, or hot towel relaxes tight muscles, improves blood flow, and helps restore range of motion. Many people find that alternating between the two gives the best results once they’re past the acute stage.
Foam Rolling
Foam rolling works by applying pressure to tight, sore tissue, helping to release tension and increase blood flow to the area. You don’t need to spend a long time on it. One to two minutes per muscle group is enough, and an entire foam rolling session shouldn’t take more than 10 minutes. You can foam roll daily or a few times a week.
Roll slowly over the sore area, pausing on tender spots for about 30 seconds before moving on. It should feel like a “good hurt,” not sharp pain. If you’re wincing or holding your breath, ease up on the pressure. A softer foam roller works fine when you’re starting out.
Eat Enough Protein
Your muscles need protein to repair the damage that causes soreness, and falling short on intake slows that process. Many people eat less protein than their muscles need for recovery. One study found that adults averaged around 62 grams per day, which sits right at the bare minimum recommendation. If you’re exercising regularly, your needs are higher.
Aim for protein at every meal rather than loading it all into dinner. Good sources include eggs, chicken, fish, Greek yogurt, beans, and tofu. Spreading your intake across the day gives your muscles a steady supply of the building blocks they need to rebuild.
Tart Cherry Juice and Anti-Inflammatory Foods
Tart cherry juice has gained a reputation as a recovery drink, and there’s reasonable evidence behind it. The pigments that give tart cherries their deep red color act as natural anti-inflammatory compounds. The typical dose used in research is about 240 to 480 mL (roughly 1 to 2 cups) of juice per day, or about 30 mL of concentrate twice daily if you’re using the concentrated form.
Beyond cherries, foods rich in similar plant compounds can support recovery. Berries, pomegranates, leafy greens, fatty fish, and turmeric all have anti-inflammatory properties. These aren’t magic bullets, but building them into your regular diet gives your body more of the raw materials it uses to manage inflammation.
Think Twice About Pain Relievers
Reaching for ibuprofen or similar anti-inflammatory drugs is a common instinct when muscles ache, but it comes with a tradeoff worth understanding. The inflammation that causes your soreness isn’t just a nuisance. It’s a necessary part of how your body repairs and strengthens muscle tissue. Inflammatory signals activate the cells responsible for rebuilding damaged fibers, and blocking those signals may compromise the repair process.
One study gave subjects the maximum over-the-counter dose of ibuprofen (1,200 mg per day) after resistance exercise and found it didn’t meaningfully reduce soreness compared to a placebo anyway. The preliminary evidence suggests that regular use of anti-inflammatory drugs after exercise may interfere with the link between muscle damage, inflammation, and regeneration. If soreness is manageable, the other strategies on this list are better first choices.
A Note on Ice Baths
Cold water immersion (ice baths in the 10 to 15°C range) can reduce soreness and help you feel recovered faster in the short term. But if your goal is building muscle or getting stronger over time, regular ice bath use may work against you. A growing body of evidence shows that routinely using cold water immersion after training sessions can blunt increases in muscle size, strength, and power. The same anti-inflammatory effect that eases soreness also dampens the signals your muscles need to adapt and grow.
If you’re training for a competition and need to recover quickly between events, ice baths make sense. If you’re trying to get stronger or build muscle over weeks and months, save them for special circumstances.
Epsom Salt Baths
Soaking in a warm bath with Epsom salts (magnesium sulfate) is a popular recovery ritual. Magnesium can be absorbed through the skin and plays a role in muscle relaxation, but the research on whether Epsom salt baths meaningfully reduce soreness is limited. That said, a warm bath on its own helps relax tight muscles and improve circulation, so even if the magnesium absorption is modest, the soak itself has value. Twenty minutes in comfortably warm water is a reasonable approach on your rest days.
When Soreness Is Something More Serious
Normal muscle soreness improves within a few days and doesn’t stop you from going about your life. Occasionally, extreme overexertion can cause a dangerous condition called rhabdomyolysis, where muscle tissue breaks down rapidly and releases its contents into the bloodstream. The CDC identifies three warning signs: muscle pain that is far more severe than you’d expect from your workout, dark urine that looks like tea or cola, and unusual weakness or fatigue that prevents you from completing tasks you’d normally handle easily. If any of these show up, get medical attention right away. Early treatment makes a significant difference in outcomes.
