Most muscle soreness after exercise peaks between 24 and 48 hours, then fades within three to five days on its own. You can speed that process along with a combination of light movement, temperature therapy, and hands-on techniques like foam rolling. Here’s what actually works, what doesn’t, and what the soreness really means.
What’s Actually Happening in Sore Muscles
The stiff, tender feeling you get a day or two after a hard workout is called delayed onset muscle soreness, or DOMS. For years, the explanation was simple: tiny tears in muscle fibers cause inflammation and pain. The reality is more nuanced. Current research suggests the soreness is tied more to inflammation in the connective tissue surrounding your muscle fibers than to damage within the fibers themselves.
During intense exercise, especially movements where your muscles lengthen under load (think: the lowering phase of a squat, running downhill, or the negative portion of a bicep curl), individual units inside your muscle fibers get overstretched. This triggers a cascade of events: calcium floods into cells, enzymes start breaking down proteins, and inflammatory signals activate pain receptors. Some of the structural changes once labeled as “damage” may actually be your muscles remodeling and adapting to handle more stress next time. That’s why the same workout feels less brutal after you’ve done it a few times.
Move Lightly the Day After
The single most effective thing you can do for sore muscles is keep moving. Active recovery, meaning low-intensity exercise at roughly 50 to 60 percent of your max effort, increases blood flow to your muscles. That extra circulation flushes out cellular byproducts from your workout and helps tissue return to its normal state faster. A 2020 review from UW Medicine found that even six to ten minutes of light cooldown activity after your workout can reduce inflammation and muscle breakdown.
What counts as active recovery depends on what made you sore. If you crushed a leg workout, try an easy bike ride, a walk, or some pool laps the next day. If your upper body is wrecked, light band work or a casual swim works well. The key is staying well below any intensity that would create new soreness. You’re not training. You’re circulating blood.
Cold Therapy, Heat Therapy, or Both
Cold and heat both reduce soreness, but they work differently. Cold narrows blood vessels and numbs nerve endings, which limits swelling and dulls pain in the short term. Heat increases blood flow and relaxes tight tissue, which can feel better for stiffness that’s already set in.
For cold, apply ice packs or a cold wrap centered over the sorest area for about 20 minutes. This works best in the first 24 hours when inflammation is ramping up. For heat, low-level heat wraps worn for several hours (research protocols used up to eight hours on the quadriceps) have shown benefits for reducing soreness and restoring range of motion once you’re past that initial inflammatory spike.
Contrast therapy, alternating between warm and cold, is another option. The standard protocol is three to four minutes in warm water (around 99 to 109°F) followed by 30 to 60 seconds of cold water (54 to 59°F), repeated for a total of 20 to 30 minutes. The alternating temperatures create a pumping effect in your blood vessels that may accelerate the clearing of inflammatory byproducts. If you don’t have access to two tubs, alternating a hot shower with cold bursts gets you partway there.
Foam Rolling Works, but Keep It Brief
Foam rolling applies pressure to the connective tissue around your muscles, helping release tension and temporarily increasing blood flow to the area. It won’t eliminate soreness, but it consistently reduces perceived pain and improves short-term range of motion. Cleveland Clinic recommends spending one to two minutes per muscle group, with the entire session lasting no more than ten minutes. You can foam roll daily or a few times a week.
Roll slowly over the sore area, pausing on particularly tender spots for 20 to 30 seconds. Avoid rolling directly over joints or bones. The pressure should feel like a “good hurt,” not sharp or unbearable. If a foam roller feels too intense on very sore muscles, a softer roller or even a tennis ball gives you more control over pressure.
Tart Cherry Juice Has Real Evidence Behind It
Among natural anti-inflammatory options, tart cherry juice has the strongest research support. The natural compounds in tart cherries reduce markers of inflammation and oxidative stress after intense exercise. The standard dose across most studies is the equivalent of 50 to 60 cherries per serving, taken twice a day: once in the morning and once in the evening.
In one study, marathon runners who drank two 8-ounce bottles of tart cherry juice daily for five days before their race, on race day, and for two days after recovered faster than those who didn’t. College athletes in another trial showed reduced soreness drinking 12 ounces of a cherry juice blend twice daily for eight days surrounding their exercise. You can find concentrated tart cherry juice at most grocery stores. The key is starting before your hard workout, not waiting until you’re already sore.
Stretching Doesn’t Prevent Soreness
This one surprises a lot of people. Despite being a near-universal gym habit, stretching before or after exercise does not reduce muscle soreness. A systematic review and meta-analysis of randomized controlled trials found no measurable effect of post-exercise stretching on soreness at 24, 48, or 72 hours compared to simply resting. Multiple independent reviews over the past two decades have reinforced the same conclusion.
That doesn’t mean stretching is useless. It can improve flexibility and feel good in the moment. But if you’re stretching specifically to prevent next-day soreness, the evidence says it won’t help. Your time is better spent on active recovery or foam rolling.
Hydration Matters, but Not for Soreness
Staying hydrated is important for exercise performance, recovery, and general health. However, research specifically testing whether dehydration makes soreness worse found no difference. A study comparing well-hydrated participants to those who restricted fluids for 72 hours after muscle-damaging exercise found that soreness levels were identical between the two groups, peaking around 48 hours and remaining elevated at 72 hours regardless of hydration status. Drink plenty of water because it supports everything else your body does during recovery, but don’t expect it to be a soreness cure on its own.
The Normal Timeline for Soreness
DOMS typically appears one to three days after your workout, with peak intensity around the 48-hour mark. By day three or four, it starts fading noticeably, and most soreness resolves within five days. If you’re returning to exercise after a break, trying a new type of workout, or significantly increasing your intensity, expect the higher end of that range.
Each time you repeat a similar workout, your muscles adapt and the soreness diminishes. This is why the first week of a new program is always the worst. Ramping up gradually, adding 10 to 15 percent more volume or intensity per week, keeps soreness manageable while still driving progress.
When Soreness Signals Something Serious
Normal DOMS is uncomfortable but manageable. It hurts when you move the affected muscles, but it doesn’t produce swelling you can see, and it steadily improves. If your soreness lasts more than a week, you may be dealing with a muscle strain or other injury rather than typical post-exercise soreness.
There’s a rarer but more dangerous condition called rhabdomyolysis, where muscle tissue breaks down so severely that it releases proteins into the bloodstream that can damage your kidneys. The hallmark warning signs are extreme muscle weakness or swelling combined with dark urine that looks brown, red, or tea-colored. Symptoms can appear one to three days after a muscle injury, overlapping with the same window as DOMS. If you notice dark urine alongside unusual muscle pain after an intense workout, that warrants immediate medical attention.
