Should Your Muscles Be Sore After Working Out?

It’s normal to feel some soreness in your muscles after working out. In fact, it can be a sign that you’re doing something right. But if you’re in too much pain, it could mean you’re overdoing it.


It is common after a hard workout to experience some muscle soreness the next day. This pain, known as “delayed onset muscle soreness” (DOMS), generally happens 24–48 hours after exercise due to microscopic tears in your muscle fibers. While feeling slight muscle soreness is an expected consequence of exercising, more severe pain can be an indication that you have done too much, or have been working out incorrectly. Understanding the reasons why you may feel DOMS and what it might mean for your health can help you decide how to adjust your routine in order to best support your physical activity goals.

What is Muscle Soreness?

Muscle soreness is a normal feeling after physical activity and occurs when the muscles are worked more intensely than they are used to. It can range from a subtle feeling of tightness, to intense aching and throbbing. Muscle soreness can be caused by a variety of factors, including inadequate warm-up, overly strenuous exercise and inadequate recovery. Let’s take a closer look at muscle soreness and why you may experience it after a workout.

Causes of Muscle Soreness

Muscle soreness, often referred to as delayed onset muscle soreness (DOMS), is a natural side effect of exercise. It may occur shortly after active movement or within 24 to 48 hours of physical activity. Muscle soreness can range from a mild discomfort to severe ache and fatigue, depending on the intensity and volume of the exercise.

When someone exerts their muscles beyond what they’re used to doing, microscopic tears occur in the muscle fibers which leads to pain and discomfort. When those tears repair themselves with proper rest and nutrition, if appropriately done, strength gains are made over time through an adaptation process — meaning your body gets stronger in order to handle the same stressors again next time.

Muscle soreness usually affects both beginners and seasoned athletes similarly with two primary causes:
-Mechanical overload: Too much overload (attributed to either too much weight lifted or incorrect form) can lead to muscle damage, resulting in delayed onset muscle soreness. This can also happen when a person is reintroduced into an activity after a long period away from it or begins a new activity that the body isn’t always adjusted for yet.
-Metabolic changes: Through increased activity levels, lactate threshold increases which then impacts digestion by releasing higher concentration of lactic acid during movement — leading to eventual burning sensation during exercise as well as post-workout muscular tension and pain.

Types of Muscle Soreness

When you’re working out, it’s important to be aware of what kind of muscle soreness you are feeling. This can provide valuable insight into your overall workout routine. Muscle soreness can generally be divided into two distinct types: the “good” kind that is the result of exercise-induced microtrauma, or the “bad” kind that could stem from overtraining, poor form while exercising, or incorrect warmups and cool downs.

The “good” type of muscle soreness, also known as delayed onset muscle soreness (DOMS), is caused by small tears in the muscle fibers as a result of exercise. This usually occurs 24-48 hours after physical activity and is generally accompanied by stiffness and reduced range of motion in the affected area. Good soreness should not impede your performance — it should make you feel like you had an effective workout session without becoming unbearable or uncomfortable for long periods of time.

On the other hand, bad muscle soreness usually occurs due to overtraining. It is most commonly caused by performing too many exercises in a given exercise session without proper warmup, using incorrect form while working out, or having poor muscle recovery following a previous workout session. This kind of soreness may take longer to go away and will likely cause significant pain during movement or simple activities such as sitting down or bending forward/backward. If left unchecked for too long, it could potentially cause more lasting injuries such as chronic inflammation which can lead to further complications with mobility and strength gains if not addressed promptly with rest days, ice baths/compressions, stretching etc..

Benefits of Muscle Soreness

Muscle soreness can often be seen as a sign of progress after a workout. It’s a natural process for your muscles to be sore after physical activity. The soreness is a result of the increased strain on them and can alert your body to the fact that you’ve been working out. In this article, let’s discuss the various benefits of muscle soreness and how it can be of help to your body.

Improved Strength

Increased muscle strength is one of the major benefits of muscle soreness when it occurs after a workout. When your muscles become sore, they are transitioning from the tearing phase to the rebuilding phase which is caused by a minor breakdown in muscle fibers. It is through this rebuilding that your body increases its strength and resistance to future workouts. By consistently pushing yourself to the point of minor soreness, you can incrementally increase your strength level over time.

Another beneficial impact of muscle soreness is improved metabolism. Due to an increased resistance on the muscle fibers in a workout, your body must burn more calories just to rebuild them in order for them to reach their point of improved strength and stamina. Post-workout protein also helps with regrowth and powering up metabolism for better performance overall.

Finally, one benefit that should not be overlooked is improved range of motion flexibility during exercise or sports activities. Through consistent repetition and controlled stretching exercises during workouts, soreness can actually improve flexibility and range of motion when performing various types of exercises or activities such as running, basketball or weightlifting among many others. Improved flexibility leads to fewer injuries and better overall performance over time.

Improved Muscle Tone

Working out regularly can lead to improved muscle tone, allowing your muscles to become stronger and more defined over time. When your muscles experience a good amount of tension and stress – such as from weight training – they respond by growing in size, increasing the amount of muscle fibers in order to better withstand the strain being placed on them. This results in toned, firm muscles.

Being sore after a workout is typically an indication that you have pushed your body to its limit, or at least beyond what it has been used to doing. As long as the soreness does not feel extreme or debilitating, it is generally safe to exercise with some discomfort. After all, your body needs time for these new demands on it for adaptation and recovery – and this includes rebuilding damaged tissue as well as creating new muscle fibers if you’re trying to gain size and strength.

Just because you are working out doesn’t mean you will always feel sore afterwards; however, being slightly sore after a workout can be beneficial if done safely within your limits. It’s important not to push yourself too hard in order to avoid any injuries due to excessive strain on weakened muscles. A properly planned regimen combined with adequate rest will help you work towards improved muscle tone without risking injury or stressing yourself too much.

Increased Endurance

Exercise-induced muscle soreness can be beneficial because it signifies that the muscles are adapting and strengthening. When muscles are put under strain, they become temporarily damaged, however, with time and rest these micro-tears heal faster and stronger than before. This means that when your muscles experience soreness after a workout, they are going to develop increased endurance.

A better understanding of this mechanism can help you to optimize your training by allowing you to understand the intensity at which you can safely push yourself without overdoing it. Training at a higher intensity will produce greater results in terms of both strength and endurance but should not be done if there is too much perceived risk of long term muscle damage or injury. The sensation of muscle soreness is an indicator that you have worked hard enough during your session but also not too hard. Additionally, as muscle endurance increases, the magnitude of post-workout soreness typically decreases over time.

Risks of Muscle Soreness

Post-workout muscle soreness is a common occurrence and can be a sign that you’ve exerted your muscles beyond their usual capacity. However, soreness that is too intense or lasts too long could indicate further problems and is important to address. In this article, we will look at the potential risks associated with muscle soreness and how to handle it.

Delayed Onset Muscle Soreness (DOMS)

Delayed onset muscle soreness (DOMS) is the pain and stiffness felt in muscles several hours to days after unaccustomed or strenuous exercise. It is thought to be caused by eccentric (lengthening) contractions of the muscle, often caused by activities like downhill running and resisted movements. It can occur irrespective of the intensity of exercise and is not necessarily related to fatigue at that time.

In most cases, DOMS resolves itself in a few days with no lasting effects; however, if the ache persists for more than a week it could indicate an underlying problem. Other causes for sore muscles include dehydration, lack of adequate stretching before exercising, lack of warm up before exercising, overworking a specific muscle group due to repeated exercises, or sudden increase in intensity or duration of exercise.

If you experience muscle soreness that does not resolve itself within about 48 hours or is accompanied by swelling or difficulty moving a particular joint – this could indicate an injury. It’s important to rest and seek medical advice if necessary before continuing with any form of exercise.


Muscles can become injured during a workout by overstretching or overworking the muscle fibers. This can lead to acute or chronic soreness, depending on the severity of the injury. It’s important to always listen to your body when engaging in physical activity and heed any warning signs of injury such as tightness in joints, discomfort, sharp pain and weakness. If these signs occur, it is recommended that you stop and take a break from your exercise session until you have consulted with a physical therapist or healthcare provider about your symptoms. In some cases, medications may be necessary for helping reduce inflammation and dulling any pain.


In conclusion, a slight amount of muscle soreness may indicate that the workout was of an adequate intensity. If the soreness persists and causes you discomfort, it would be worth consulting with a healthcare professional for further advice. In certain cases, increased muscle soreness on consecutive days may indicate that the intensity or duration of workouts is too high and should be adjusted accordingly. Additionally, if you have any pre-existing health conditions or feel that something is wrong, make sure to speak with your doctor before undertaking any physical activity. Ultimately, working out should benefit your overall well-being and if your muscle soreness persists seek medical help!
