Post-workout soreness usually peaks one to three days after exercise and resolves within five days. You can speed that process along with a combination of light movement, targeted self-massage, temperature therapy, and good sleep. The soreness itself is a normal response to exercise that pushes your muscles beyond what they’re used to, and most recovery strategies work by increasing blood flow, reducing inflammation, or giving your body the raw materials it needs to repair.
Why Your Muscles Feel Sore
When you exercise harder than your body is accustomed to, the effort creates tiny disruptions in your muscle fibers, particularly where the muscle connects to tendon tissue. These micro-tears aren’t injuries in the traditional sense. They’re a normal part of how muscles adapt and grow stronger. But the damage triggers an inflammatory response: white blood cell counts rise, fluid accumulates around the affected fibers, and pain receptors in the area become sensitized. That combination of structural damage, swelling, and inflammation is what makes your legs burn going down stairs two days after a heavy squat session.
This is called delayed onset muscle soreness, or DOMS. It typically starts 12 to 24 hours after your workout, peaks somewhere between 24 and 72 hours, and rarely lasts more than five days. Eccentric movements (the lowering phase of a lift, running downhill, or any motion where the muscle lengthens under load) cause the most soreness because they place the greatest mechanical stress on individual fibers.
Move Lightly the Next Day
The single most effective thing you can do for sore muscles is keep moving. Light activity, often called active recovery, increases blood flow to damaged tissue, which flushes out the cellular byproducts of exercise and helps your muscles return to normal faster. A mix of light movement and passive recovery techniques like cold water or compression is now considered the gold standard for repairing strained tissue.
Active recovery doesn’t mean repeating your workout at lower intensity. It means genuinely easy movement: a 20-to-30-minute walk, an easy bike ride, swimming at a conversational pace, or a gentle yoga flow. The goal is circulation, not stimulus. If the activity itself makes your soreness worse while you’re doing it, you’ve gone too hard.
Foam Rolling and Self-Massage
Foam rolling works by applying pressure to tight, knotted muscle tissue, helping loosen adhesions and increase local blood flow. The key is keeping your sessions short. Roll each muscle group for about one minute, and don’t exceed two minutes on any single area. If you find a particularly tight knot, hold pressure on it for no more than 30 seconds before moving on. Setting a timer can help you avoid overdoing it, which can actually increase inflammation rather than reduce it.
Rolling before your next workout can improve range of motion, and rolling after exercise may reduce how sore you feel the following day. Consistency matters more than intensity here. Moderate, sustained pressure is more productive than grinding into the muscle as hard as you can tolerate.
Cold Water, Hot Water, or Both
Cold water immersion is effective at reducing inflammation, swelling, and the subjective feeling of fatigue after intense exercise. Research on high-intensity interval training found benefits from soaking in water around 59°F (15°C) after a session. If you don’t have a cold plunge setup, a cold bath or even a cool shower focused on sore areas can help.
Heat works differently. Hot water immersion (around 104°F or 40°C) appears to be better at maintaining exercise performance in subsequent sessions, likely because warmth relaxes muscle tissue and promotes blood flow without the temporary stiffness cold can cause. For pure soreness relief, cold has a slight edge. For getting back to training feeling functional, heat may be the better choice. Many athletes alternate between the two, and there’s no wrong answer. Use whichever feels better to you, or try contrast showers (alternating warm and cool water) for a middle ground.
Sleep Is When Repair Happens
Your body does its heaviest tissue repair work during deep sleep. Shortly after you fall asleep, growth hormone is released in relatively large amounts into your bloodstream, and this early-night surge drives much of the muscle regeneration process. Sleep deprivation studies consistently point to deep sleep as a dependency for these regeneration processes. If you’re cutting sleep short, whether from late nights or early alarms, you’re directly slowing down the recovery you’re trying to accelerate.
Seven to nine hours is the standard recommendation, but the quality of that sleep matters too. Alcohol, screen exposure before bed, and inconsistent sleep schedules all reduce the amount of time you spend in deep sleep stages, even if you’re technically in bed long enough.
What to Eat and Drink
Adequate protein after exercise gives your body the amino acids it needs to rebuild damaged muscle fibers. Spreading protein intake across meals (rather than loading it all into one post-workout shake) supports a steadier supply of building blocks throughout the day. Most people benefit from 20 to 40 grams of protein per meal.
Magnesium plays a role in muscle relaxation and has anti-inflammatory properties that may help with post-exercise soreness and fatigue. It also appears to reduce lactate levels after exercise. That said, supplementing with magnesium only helps if your levels are low to begin with. People with normal magnesium levels don’t see additional benefit from extra supplementation. Leafy greens, nuts, seeds, and whole grains are the best dietary sources.
Tart cherry juice is a popular recovery drink, typically consumed in doses of 240 to 480 mL (about 8 to 16 ounces) daily. While it contains compounds that may reduce inflammation, the scientific evidence for its effect on muscle soreness specifically remains limited. It’s unlikely to hurt, but don’t expect it to replace the strategies above.
Staying well hydrated matters more than any supplement. Dehydration concentrates inflammatory markers in your blood and slows the delivery of nutrients to damaged tissue. Water is sufficient for most workouts. If you’ve sweated heavily for over an hour, adding electrolytes helps replace what you’ve lost.
Over-the-Counter Pain Relief
Ibuprofen and other anti-inflammatory medications do reduce soreness. A common concern is that blocking inflammation might also block muscle growth, since inflammation is part of the repair and adaptation process. Recent research has challenged this idea. A study combining rodent exercise data with human muscle biopsy analysis found that neither chronic low-dose nor acute high-dose anti-inflammatory use significantly affected muscle size or the signaling pathways that drive muscle protein synthesis. In practical terms, taking ibuprofen occasionally for soreness is unlikely to undermine your training gains.
That said, regular use of anti-inflammatories comes with its own downsides, including stomach irritation and kidney stress. Use them as a short-term tool for especially bad soreness rather than a daily habit.
When Soreness Is Something More Serious
Normal DOMS is uncomfortable but manageable, and it improves a little each day. If your soreness lasts longer than a week, you may be dealing with a muscle strain or other injury rather than typical post-exercise soreness.
A rare but dangerous condition called rhabdomyolysis occurs when muscle breakdown is so severe that cellular contents leak into the bloodstream and can damage the kidneys. The warning signs are muscle pain that feels more severe than expected, dark tea- or cola-colored urine, and unusual weakness or fatigue (like being unable to finish a workout you’ve done before). Symptoms can appear hours to days after the triggering exercise. You can’t distinguish rhabdomyolysis from severe DOMS by symptoms alone, so if you notice dark urine or extreme pain after a workout, especially one that was unusually intense or unfamiliar, get a blood test. It’s the only reliable way to confirm or rule it out.
