The best things you can do for muscle soreness are stay lightly active, apply cold or heat strategically, and give your body adequate nutrition and rest. Most post-exercise soreness peaks between one and three days after your workout and resolves within five days. If it lingers beyond a week, you’re likely dealing with something more than typical soreness.
Why Your Muscles Hurt After Exercise
When you exercise intensely, especially with movements that lengthen muscles under load (think: lowering a heavy weight, running downhill, or the down phase of a squat), the strain causes tiny structural disruptions inside muscle fibers. Calcium floods into the damaged cells and triggers enzymes that break down contractile proteins, which is why you lose some strength in the hours and days that follow.
Your body then launches an inflammatory response to clean up and rebuild. Immune cells flood the area, clearing debris and laying the groundwork for stronger tissue. This inflammation is what generates the aching, stiffness, and tenderness you feel. Importantly, this process is not a sign of harm. It’s the mechanism your body uses to adapt and grow stronger. The goal of recovery isn’t to eliminate inflammation entirely but to support it so your body can do its job efficiently.
Keep Moving With Light Activity
The single most effective thing you can do when you’re sore is move. Not another hard workout, but gentle, low-intensity activity: a walk, an easy bike ride, some bodyweight mobility work. Muscles and joints rely on circulation to deliver nutrients and flush waste products from tissue breakdown. When you compress and release muscle tissue through movement, you push out old fluid and draw in fresh blood. That’s why you feel stiff and heavy first thing in the morning but noticeably better after a few minutes on your feet.
Mobility exercises that take your joints through their full range of motion are particularly useful because they increase blood flow to surrounding muscles without overloading any single one. The key is staying well below your normal workout intensity. You’re after circulation, not stimulus.
Cold, Heat, or Both
Cold therapy (ice baths, cold packs, cold water immersion) is effective at reducing soreness symptoms within the first 24 hours after exercise, but the benefit fades after that window. Heat therapy works differently: it continues to provide relief both within and beyond 24 hours, with simple heat packs performing particularly well. Contrast therapy, alternating between hot and cold water, also outperforms doing nothing.
By the 72-hour mark, studies show the differences between cold, heat, and no treatment largely disappear. So temperature therapy is most valuable in those first couple of days when soreness is at its worst. A practical approach: use cold right after a tough session if swelling is a concern, then switch to heat in the following days to promote blood flow and relax tight tissue.
Foam Rolling
Foam rolling has a measurable effect on reducing muscle soreness, though the benefit is modest immediately after exercise and becomes more pronounced at 24, 48, and 72 hours. A meta-analysis of multiple studies found that rolling after exercise produced a small but statistically significant reduction in perceived pain at every time point measured.
The mechanism is similar to light activity and massage: applying pressure to tissue helps circulate fluid, delivers fresh blood, and may reduce localized stiffness. Spend one to two minutes per muscle group, rolling slowly over sore areas. You don’t need to grind into the most painful spots. Moderate, tolerable pressure works.
Compression Garments
Wearing compression sleeves, tights, or socks after hard exercise can speed functional recovery by reducing the space available for swelling and improving blood return to the heart. Studies have consistently shown faster recovery of movement and performance within the first 24 to 48 hours for people wearing compression gear, with runners recovering up to 6% faster in that window. The biggest benefits show up after endurance exercise and heavy eccentric training.
Wearing compression intermittently after the first 24 hours continues to provide some benefit for an additional two to three days. If you already own compression gear, wearing it in the hours after a tough workout is one of the easier recovery strategies to implement.
Think Twice Before Reaching for Ibuprofen
Over-the-counter anti-inflammatory drugs like ibuprofen are tempting when you’re sore, but they come with a meaningful tradeoff if you’re training to build muscle. A study from Karolinska Institutet assigned young adults to take either a standard daily dose of ibuprofen (1,200 mg) or a low dose of aspirin while following the same weight training program for eight weeks. The group taking ibuprofen gained half the muscle volume of the aspirin group. Strength gains were also blunted, though less dramatically.
The reason ties back to the inflammation process itself. Those inflammatory signals that make your muscles sore are also what drive the building of new muscle tissue. Suppressing them with regular anti-inflammatory use appears to interfere with long-term adaptation. Occasional use for acute pain is one thing, but daily dosing through a training block can undermine your results.
Nutrition and Magnesium
Adequate protein and overall calorie intake give your body the raw materials it needs to repair damaged muscle fibers, but one nutrient deserves special attention: magnesium. Magnesium plays a role in muscle relaxation, reduces central pain sensitivity by blocking certain receptors in the nervous system, and has anti-inflammatory properties that support recovery from exercise-induced damage. Low magnesium levels can cause cramps, weakness, and fatigue on their own.
For active people, increasing magnesium intake by 10 to 20 percent above the standard recommended amount, ideally taken about two hours before exercise, may help with soreness and recovery. That said, if your magnesium levels are already normal, supplementing further won’t raise your blood levels or improve symptoms. You can get magnesium from dark leafy greens, nuts, seeds, and whole grains before considering a supplement.
Tart cherry juice has attracted attention for its high concentration of anthocyanins, plant compounds with anti-inflammatory properties. Early research found that drinking tart cherry juice for several days before and after intense exercise reduced pain and improved strength recovery. However, more recent studies using single-dose strategies have failed to replicate those results. The evidence, taken together, suggests tart cherry juice may help if consumed consistently in the days surrounding hard training, not as a one-time fix.
When Soreness Is Something More Serious
Normal muscle soreness feels like widespread achiness and stiffness in the muscles you worked. It builds gradually over hours, peaks between one and three days later, and fades within five days. If your soreness lasts a week or more, it could indicate a muscle strain rather than typical post-exercise soreness.
Rhabdomyolysis is a rare but serious condition where muscle breakdown becomes severe enough to release cellular contents into the bloodstream. The warning signs are muscle pain that feels far worse than you’d expect for the effort, dark tea or cola-colored urine, and unusual weakness or fatigue that prevents you from completing normal activities. You can’t diagnose it from symptoms alone since dehydration and heat cramps can look similar. A blood test measuring a specific muscle protein is the only reliable way to confirm it. If you notice dark urine after an unusually intense workout, especially one involving movements you aren’t accustomed to, seek medical attention promptly.
