The fastest way to get soreness out of your legs is a combination of light movement, temperature therapy, and time. Most exercise-related leg soreness, known as delayed onset muscle soreness (DOMS), starts one to three days after a workout and resolves within five days. You can speed that process up and reduce the discomfort significantly with a few proven strategies.
Why Your Legs Get Sore in the First Place
Leg soreness after exercise isn’t caused by lactic acid buildup, despite what you may have heard. Scientists have studied DOMS for over a century without settling on a single explanation, but the current understanding points to microscale damage at the nerve and muscle fiber level. When you push your legs harder than they’re used to, tiny injuries occur in the tissue. Your body responds with inflammation, which is part of the repair process but also what makes your legs feel stiff, tender, and heavy.
This is why soreness doesn’t hit immediately. The inflammatory response and nerve signaling changes take time to ramp up, peaking around 24 to 72 hours after the workout. Downhill running, heavy squats, lunges, and any movement where your muscles lengthen under load (like lowering yourself into a step) tend to cause the most soreness.
Move at Low Intensity
The single most effective thing you can do for sore legs is keep them moving. Sitting still feels tempting, but light activity increases blood flow to the damaged tissue, delivering nutrients and clearing inflammatory byproducts. This is called active recovery, and it works best when you keep your heart rate between 30 and 60 percent of your maximum.
Walking is the easiest option. A 20 to 30 minute walk at a comfortable pace is enough to loosen stiff legs without adding more stress. Swimming, easy cycling, yoga, and gentle stretching all work well too. The key is genuinely low intensity. If you’re breathing hard or your legs feel like they’re working, you’ve gone too far. Think of it as movement for circulation, not fitness.
Use Heat or Cold Strategically
Both heat and cold can help sore legs, but they work differently. Cold reduces swelling and temporarily numbs pain. If your legs feel inflamed or puffy, especially in the first 24 hours, a cold bath at around 59°F (15°C) can take the edge off. Heat, on the other hand, relaxes tight muscles and increases blood flow. A warm bath at around 104°F (40°C) or a heating pad can feel more comfortable and may actually do more for maintaining your performance in subsequent workouts. Research from the American Physiological Society suggests hot water immersion may be better than cold for maintaining exercise performance.
A practical approach: use cold if your legs feel swollen or acutely painful in the first day, then switch to warmth on days two and three to promote circulation and relaxation. A warm shower or bath before bed can also help you sleep more comfortably when soreness peaks.
Foam Roll, but Don’t Overdo It
Foam rolling your quads, hamstrings, and calves can reduce the intensity and duration of soreness. It works by increasing local blood flow and temporarily reducing muscle tension. Roll each muscle group for about one minute, and don’t exceed two minutes per area. Setting a timer helps, because it’s easy to grind into a sore spot longer than you should.
Use slow, steady passes over the muscle rather than rapidly rolling back and forth. When you hit a particularly tender spot, pause on it for 15 to 20 seconds and let the pressure do the work. Foam rolling is uncomfortable on sore muscles, but it shouldn’t be sharp or unbearable. If you don’t have a foam roller, a tennis ball or lacrosse ball works for smaller areas like calves and the sides of your thighs.
What to Eat and Drink
Hydration matters more than most people realize. Dehydrated muscles recover more slowly and feel stiffer. Aim to drink enough water that your urine stays pale yellow throughout the day, especially in the 48 hours after a hard leg workout.
Protein is the raw material your muscles need to repair. Getting 20 to 40 grams of protein within a few hours of your workout, and maintaining adequate protein intake over the following days, supports the recovery process. Good sources include eggs, chicken, Greek yogurt, fish, or a protein shake if whole food isn’t convenient.
Tart cherry juice has gained popularity as a recovery drink due to its high concentration of anthocyanins, plant compounds with anti-inflammatory properties. Studies have typically used 150 to 355 mL (roughly 5 to 12 ounces) of tart cherry juice twice a day, often starting a few days before heavy exercise and continuing for two days after. The evidence is mixed, though. Some studies show modest reductions in soreness, while others, including a 2024 study in PLOS ONE, found no significant recovery benefit compared to a sports drink. It’s unlikely to hurt, but don’t expect it to be a magic fix.
Compression Can Help
Compression socks or sleeves apply gentle pressure to your legs, which can reduce swelling and may lessen the sensation of soreness. Compression garments designed for recovery typically fall in the low to medium range (under 30 mmHg of pressure). You wear them during the day and take them off at night. Many runners and cyclists find compression most helpful in the 24 to 48 hours after a hard session, particularly if they’re on their feet a lot during the day. They won’t dramatically speed healing, but they can make sore legs feel more supported and less heavy.
What Not to Do
Avoid intense stretching of already sore muscles. Gentle movement is fine, but aggressively stretching a quad or hamstring that’s inflamed can add microtrauma and make things worse. Similarly, don’t try to “push through” soreness with another hard leg workout. Your muscles need time to repair, and training them hard again before they’ve recovered increases your risk of injury and delays the process.
Anti-inflammatory medications like ibuprofen can mask pain, but using them routinely after workouts may interfere with the muscle adaptation process. Occasional use for severe discomfort is fine, but don’t make it a habit for every sore day.
When Soreness Is Something More Serious
Normal DOMS makes your legs feel stiff, tender, and weak, but it improves steadily over three to five days. Certain warning signs suggest something beyond typical soreness. The CDC identifies these red flags for rhabdomyolysis, a potentially dangerous condition where muscle tissue breaks down and releases proteins into the bloodstream:
- Dark urine that looks tea or cola colored
- Pain far more severe than expected for the workout you did
- Extreme weakness or fatigue, especially an inability to complete tasks you’d normally handle easily
Rhabdomyolysis symptoms can appear hours to days after exercise, which makes it easy to confuse with DOMS early on. If your soreness is getting worse rather than better after 48 hours, or you notice any change in urine color, seek medical care promptly. This is rare, but it’s most common after unusually intense exercise, particularly in hot conditions or when you’ve jumped into a workout well beyond your current fitness level.
