The best things you can do for sore legs after a workout are light movement, foam rolling, and giving your body the nutrition it needs to repair. That soreness, which typically peaks 24 to 72 hours after exercise, is a normal response to microscopic damage in your muscle fibers and surrounding connective tissue. It’s not a sign you did something wrong. But there are proven ways to reduce it and recover faster.
Why Your Legs Get Sore After Exercise
Post-workout leg soreness is called delayed onset muscle soreness, or DOMS. It happens when exercise creates tiny tears in your muscle fibers, especially during movements where your muscles lengthen under load (think: the lowering phase of a squat or walking downhill). There isn’t one single cause. Instead, it’s a chain reaction: micro-tears trigger inflammation, which causes fluid and electrolyte shifts in the tissue, and muscle spasms can layer on top of all that. The result is stiffness, tenderness, and that familiar ache when you try to sit down or climb stairs.
DOMS usually shows up 12 to 24 hours after your workout and peaks between 24 and 72 hours. It resolves on its own within a few days. Everything below can shorten that window or take the edge off while your body does its work.
Move at Low Intensity
It sounds counterintuitive, but one of the fastest ways to reduce sore legs is to use them. Low to moderate intensity movement increases blood flow, which helps clear inflammatory byproducts from damaged tissue and delivers the nutrients your muscles need to rebuild. Light exercise also triggers your body’s natural painkillers, endorphins, which reduce how much soreness you actually feel.
Walking, easy cycling, and light jogging all work. Research comparing these options found that cycling is particularly effective for leg soreness. Moderate intensity cycling outperformed both running and complete rest when it came to reducing pain and restoring strength in the days after a hard lower body workout. A 20 to 30 minute spin at an easy pace the day after leg day is one of the simplest recovery tools available.
Foam Roll Your Legs
Foam rolling applies direct pressure to sore muscle tissue, and the evidence supports it as a genuinely useful recovery tool. In a study on DOMS recovery, a 20-minute foam rolling session done immediately after exercise and repeated every 24 hours significantly reduced muscle tenderness and helped maintain performance in multi-joint movements like jumping and sprinting.
The protocol that worked: roll each muscle group in your lower body for about 45 seconds, rest 15 seconds, then repeat. Hit your quads, hamstrings, glutes, and calves on both sides. The total session takes about 20 minutes. Use a high-density roller and expect it to feel uncomfortable on the sorest spots. That pressure is part of what makes it effective.
Try Cold Water or Ice
Cold water immersion reduces soreness after exercise, though researchers still haven’t nailed down the single best way to do it. A large Cochrane review of the evidence found that water temperatures below 15°C (59°F) are the standard used across studies. Immersion times ranged widely, from 5 to 24 minutes, with an average of about 12 to 13 minutes of continuous soaking.
If you don’t have access to an ice bath, a cold shower focused on your legs for several minutes can still help. Some people prefer alternating cold and room temperature water. The goal is to constrict blood vessels in the damaged tissue, which limits the inflammatory swelling that contributes to soreness and stiffness.
Wear Compression Clothing
Compression tights or sleeves worn during and after a hard leg workout provide a moderate but consistent reduction in DOMS severity. A meta-analysis in the British Journal of Sports Medicine found that wearing compression garments after intense exercise produced a meaningful decrease in soreness compared to going without. The key is putting them on within a couple hours of finishing your workout. There’s no agreed-upon minimum wear time, but wearing them for the rest of the day or overnight is a common approach among athletes.
Prioritize Protein Intake
Your muscles can only repair themselves if you give them the raw materials. For people training hard enough to cause regular soreness, research points to 1.6 to 2.2 grams of protein per kilogram of body weight per day as the range that optimizes muscle repair and growth. For a 150-pound person, that’s roughly 109 to 150 grams of protein spread across the day.
Timing matters less than people once thought. The old “30-minute anabolic window” has largely been debunked. What does matter is having a protein-rich meal or snack both before and after your workout, ideally within about 4 to 6 hours of each other. A good target for each of those meals is about 0.4 to 0.5 grams of protein per kilogram of your lean body mass. For most people, that translates to 25 to 40 grams of protein per sitting.
Tart Cherry Juice as a Recovery Drink
Tart cherry juice contains natural compounds that reduce inflammation and oxidative stress in muscle tissue. But there’s an important catch: it only works if you start drinking it before your workout, not after. Studies have consistently shown that muscle function recovers faster when tart cherry juice is consumed for several days leading up to hard exercise. Starting it on the day of your workout or afterward doesn’t produce the same benefits.
If you want to try it, the typical protocol is two servings per day for about four to five days before a hard training session and continuing for a couple of days after. For concentrate, that’s two 30 ml (one ounce) servings daily. For fresh-frozen juice, servings range from about 237 to 355 ml (8 to 12 ounces) twice a day. This makes tart cherry juice more of a planning tool than a quick fix, best suited for people who know a particularly tough leg day is coming.
Magnesium for Muscle Recovery
Magnesium plays a direct role in muscle contraction and relaxation, and people who exercise intensely need 10 to 20% more of it than sedentary people. The recommended daily intake for adults is 400 to 420 mg for men and 310 to 320 mg for women, so active individuals should aim for the higher end or slightly above.
Not all forms of magnesium are equally useful. Magnesium citrate appears to be the most effective form for muscle function based on available comparisons. Magnesium glycinate (around 350 mg daily) has also been studied with positive results. Taking it about two hours before training may offer the most benefit. Many people get enough magnesium through foods like spinach, pumpkin seeds, almonds, and black beans, but supplementation can fill the gap if your diet falls short.
When Soreness Is Something More Serious
Normal DOMS is uncomfortable but manageable. Rhabdomyolysis is a rare but dangerous condition where muscle breakdown floods your bloodstream with proteins that can damage your kidneys. It can happen after unusually intense exercise, especially if you’re new to training or dramatically increase your volume.
The warning signs that separate rhabdomyolysis from regular soreness: pain that feels far more severe than you’d expect for the workout you did, dark urine that looks like tea or cola, and unusual weakness or fatigue where you can’t complete tasks you normally handle easily. These symptoms can show up hours or even days after the workout. If your urine turns dark after a hard leg session, that warrants immediate medical attention.
