The most effective way to help with soreness after a workout is light movement the next day, adequate protein intake, and simply giving your muscles time. Post-workout soreness typically starts 12 to 24 hours after exercise, peaks between one and three days later, and fades on its own after that. Most popular remedies have weaker evidence than people assume, so knowing what actually works saves you time and effort.
Why Your Muscles Get Sore
Soreness after exercise comes from microscopic damage to your muscle fibers, particularly during movements where your muscles lengthen under load. Lowering a heavy weight, running downhill, or the downward phase of a squat all count. This micro-damage triggers an inflammatory response: your body sends immune cells to the area to clean up damaged tissue and start rebuilding.
That inflammation is what makes you stiff and tender. It used to be considered a problem, but it’s now understood to be a necessary part of how muscles repair and grow stronger. The soreness isn’t a sign that something went wrong. It’s a sign that your body is doing exactly what it’s supposed to do after being challenged by unfamiliar or intense exercise.
What Actually Helps
Light Movement
The single best thing you can do for sore muscles is move them gently. An easy walk, a slow swim, light yoga, or just a “shake-out” jog all increase blood flow to the affected muscles. That blood flow flushes out cellular byproducts from the workout and helps your muscles return to normal faster. You don’t need to do much. Even six to ten minutes of light activity at about half your usual effort can reduce inflammation and muscle breakdown.
The key is keeping intensity low. If your legs are sore from squats, a 20-minute walk is ideal. A hard run is not. You’re trying to circulate blood, not create more damage.
Protein
Your muscles can’t repair micro-tears without adequate protein. Sports nutrition experts generally recommend 1.6 to 2.2 grams of protein per kilogram of body weight per day for people doing regular resistance training. For a 70 kg (154 lb) person, that’s roughly 112 to 154 grams daily. The timing matters less than the total: spread it across your meals in whatever way you can maintain consistently, and your muscles will have what they need to rebuild.
Sleep
Most muscle repair happens during sleep, when your body releases growth hormone and directs resources toward tissue recovery. Cutting sleep short after a hard workout meaningfully slows the process. If you’re consistently sore for longer than expected, poor sleep is one of the first things worth examining.
Cold Water Immersion
Ice baths are one of the more studied recovery tools, and the evidence suggests they can reduce perceived soreness. Research points to water temperatures around 11°C (52°F), with immersion lasting 11 to 15 minutes for the best results. Temperatures in studies range from 8 to 15°C (46 to 59°F), so you don’t need to be precise.
That said, cold exposure blunts the inflammatory response, which is the same process that drives muscle adaptation. If your goal is to build muscle over time, frequent ice baths after strength training may work against you. They make more sense for athletes who need to recover quickly between competitions than for someone focused on long-term strength gains.
What Doesn’t Work as Well as You’d Think
Stretching
Multiple meta-analyses have found that stretching before or after exercise does not protect against soreness. Compared to simply resting, stretching produced no measurable difference in soreness levels, muscle strength recovery, or markers of muscle damage at any time point. Stretching has other benefits for flexibility and mobility, but reducing next-day soreness isn’t one of them.
Foam Rolling
Foam rolling feels good in the moment, but the evidence for recovery is surprisingly thin. Studies have tested durations ranging from 45 seconds to 5 minutes per muscle group, and there are currently no established guidelines. Research on one- and two-minute sessions per muscle group found no significant benefit for soreness recovery. Longer durations might help, but the science hasn’t confirmed a clear dose that works. If foam rolling feels like it helps you, there’s no harm in continuing, but don’t count on it as a primary recovery strategy.
Anti-Inflammatory Painkillers
Ibuprofen and similar drugs will dull the pain, but there’s a real cost. A study from Karolinska Institutet had young adults take 1,200 mg of ibuprofen daily (a standard full-day dose) while doing supervised weight training for eight weeks. The group taking ibuprofen gained only half the muscle volume compared to a group taking a low dose of aspirin. Muscle strength was also impaired, though less dramatically. The reason: those drugs suppress the very inflammatory processes that drive muscle growth. For young people training to build muscle, regular high-dose anti-inflammatory use is counterproductive.
Occasional use for severe soreness is a different story, but reaching for ibuprofen after every workout undermines the adaptation you’re training for.
Tart Cherry Juice
Tart cherry juice is frequently recommended for post-workout soreness, and while it does contain compounds with anti-inflammatory properties, the scientific evidence for its effectiveness remains weak. Typical doses used in studies range from 240 to 480 mL daily. It’s unlikely to cause harm, but it shouldn’t be your primary recovery plan.
How to Prevent Excessive Soreness
Soreness is most intense when you do something your body isn’t used to. A new exercise, a big jump in weight, or returning to the gym after a break will all produce more soreness than a familiar routine. The most reliable way to minimize it is progressive overload: increase volume or intensity by small amounts each week rather than making dramatic jumps. Your muscles adapt quickly. An exercise that leaves you barely able to walk on week one may produce almost no soreness by week three.
A proper cooldown also helps. Six to ten minutes of easy movement at 50 to 60 percent of your max effort immediately after training can reduce the inflammatory response and muscle breakdown that follows. This is different from stretching. Think a slow jog after a run, or easy cycling after a leg workout.
When Soreness Is Something More Serious
Normal soreness makes you stiff and tender. It’s uncomfortable but manageable, and it gets better each day. Rhabdomyolysis is a rare but dangerous condition where damaged muscle fibers release their contents into the bloodstream, potentially harming the kidneys. The CDC identifies these warning signs:
- Pain far more severe than expected for the workout you did
- Dark urine that looks like tea or cola
- Unusual weakness or fatigue, such as being unable to complete tasks you could normally handle
Symptoms can appear hours or even days after the workout. Rhabdomyolysis is most common after extreme or unfamiliar exertion, especially in hot conditions. If your soreness feels disproportionate to what you did and your urine is noticeably dark, that warrants prompt medical attention.
