Sore muscles are a common side effect of exercise, particularly when the workout is new or more intense than usual. This is known as delayed-onset muscle soreness (DOMS) and is caused by small tears in the muscle fibres, which repair and make the muscle stronger. While there is no way to speed up this process, there are several ways to treat or reduce the symptoms of soreness.

What You'll Learn

Warm up and cool down
Warming up before a workout is critical for preventing injury and preparing your body for the upcoming activity. It increases the temperature and flexibility of your muscles, helping you perform better and be safer during your workout. A good warm-up involves low-heart-rate cardio, which prepares the circulatory and respiratory systems for the upcoming activity. It also widens your blood vessels, ensuring that your muscles are well-supplied with oxygen and helps minimise stress on your heart.
The type of warm-up activities you perform depends on the type of exercise you will be doing. For example, if you plan on running, walking, or cycling, start with the same activity but at a slower pace. If you're weightlifting, begin with easy repetitions of light hand weights before moving on to more intense exercises. The warm-up should last for about 5 to 10 minutes, and the more intense the activity, the longer the warm-up should be.
Cooling down after a workout is just as important as warming up. After physical activity, your heart rate and blood pressure are still elevated, your body temperature is higher, and your blood vessels are widened. Stopping suddenly can cause light-headedness or even make you feel sick or pass out. A cool-down allows a gradual decrease in these physiological responses to exercise. It keeps the blood flowing throughout the body and helps your muscles recover.
To cool down, reduce your walking speed for 5 to 10 minutes to allow your heart rate to slow down. It is also a good time to stretch because your limbs, muscles, and joints are still warm. Stretching can help reduce the buildup of lactic acid, which can lead to muscle cramping and stiffness. Hold each stretch for 10 to 30 seconds, and if you feel you need more, stretch the other side and return for another set. The stretch should be strong but not painful, and you should breathe while stretching without bouncing.

Stretch
After a workout, gentle stretching can help to reduce muscle soreness and aid recovery by improving blood flow and breaking down the build-up of lactic acid in the muscles. It is important to be careful and gentle when stretching sore muscles to avoid further injury. Focus on the muscles that are giving you discomfort, such as your calves, thighs, hamstrings, or shoulders. For example, to stretch your calf muscles, stand with one leg behind you, digging your heel into the ground, and lean forward. To stretch your hamstrings, stand with your feet together and bend over at the waist, rolling your spine forward and reaching towards the floor.
Static stretches involve lengthening a muscle and holding the stretch for 20-60 seconds for adults and 10-15 seconds for children. You can also time your stretches by taking deep breaths, aiming for at least three deep breaths per stretch. If any stretching causes pain, stop and rest. It is important to listen to your body and not push yourself too far.
In addition to stretching, there are other ways to relieve sore muscles, including icing, heat therapy, foam rolling, and staying hydrated before and after your workout.

Ice and heat therapy
When used simultaneously, ice and heat therapy can provide a more comprehensive approach to muscle recovery. Ice therapy is useful for reducing swelling, inflammation, and pain caused by tissue damage, such as sprains, strains, or pulled muscles. It can also help reduce painful muscle spasms. On the other hand, heat therapy helps open blood vessels, increasing blood flow to the affected area. This increased circulation can assist in the healing process and alleviate pain. Heat therapy is particularly beneficial for injuries that are a few days old and for soothing sore muscles that cause back or neck pain. It is also useful for loosening muscles when experiencing tension headaches.
When used at different stages of recovery, ice and heat therapy can complement each other. Ice therapy is typically recommended as the first step in treating acute injuries or soreness. It helps reduce swelling and pain, making it ideal for immediate application after intense physical activity or injury. A few hours later, heat therapy can be applied to stimulate blood flow to the affected muscles, helping them remain limber and relaxed. This approach is known as contrasting therapy and is often recommended by experts to enhance recovery and provide a more comprehensive treatment.
It is important to note that the duration and frequency of ice and heat therapy sessions should be carefully considered. Ice therapy should be limited to 10–20 minutes at a time, and it is crucial to avoid direct contact between ice and the skin to prevent frostbite or nerve injury. Heat therapy should be applied for around 10–20 minutes, and it is essential to use a barrier, such as a towel, between the heat source and the skin to prevent burns. Additionally, heat therapy should not be used within the first 48 hours after an injury, as it can increase bleeding.

Hydration
Staying hydrated is critical for muscle recovery and healing. Dehydration can exacerbate chronic muscle and joint pain, slow the rate of healing, and increase the chances of injury. Water helps hydrate the discs between the vertebrae in your spine and prevents your tendons, ligaments, and muscles from becoming tight and stiff. It also helps to keep the cartilage soft and pliable.
To prevent dehydration, it is recommended to drink plenty of water before, during, and after a workout session. This ensures you have enough fluids to replace the water lost through sweat. Recommended amounts vary based on your height, weight, body composition, and activity level. Generally, it is recommended that women drink 91 ounces of water per day, and men drink 125 ounces per day. It is also suggested to drink half of your body weight in fluid ounces of water per day. For example, if you weigh 128 lbs (58 kg), you should consume 64 fl oz (1,900 ml) of water per day.
Drinking a full glass of water when you wake up in the morning can help you stay hydrated throughout the day. It is also beneficial to include high-water-content fruits and vegetables in your diet, such as cucumber, celery, watermelon, strawberries, spinach, and tomatoes. These foods can be added to your water for extra flavour.
Proper hydration also requires electrolytes, the minerals lost in sweat, such as sodium, chloride, potassium, and magnesium. While a regular gym session may not require a sports drink, long-distance runners, triathletes, or those who train with great intensity, should consider replenishing their electrolytes. Coconut water is a great natural option for this.
Drinking ice-cold water immediately after an intense muscle workout can effectively reduce muscle soreness. It reduces muscle inflammation and prevents soreness from lingering. Taking an ice bath or a cold shower can also help, but if you can't tolerate the cold, a regular cold tap water bath or shower will do the trick.

Rest
It is recommended that you rest both before and after an intense workout. A 2018 study on active recovery found that runners who spent time at a 50% decrease in activity at the end of their workout (instead of resting completely) were able to go three times longer the second time they ran. This is because the reduced activity helps improve blood flow, reducing blood lactate—the metabolic byproduct that makes your muscles sore.
It is also important to get a good night's sleep. A lack of sleep can contribute to higher levels of inflammation, which can cause muscle soreness.
If you are experiencing muscle soreness, it is recommended that you take a break from intense exercise and give your muscles time to recover. This does not mean that you have to be completely sedentary—low-impact activities such as walking or swimming can help improve blood flow to sore muscles and aid in recovery.
If you are experiencing muscle soreness after a workout, it is important to listen to your body and give your muscles the rest they need. Pushing yourself too hard can lead to further injury and prolonged recovery time.
