A Broth & Co guide to post-workout soreness, eccentric exercise, recovery, adaptation and training confidence.

You finish a workout feeling surprisingly good. The next morning your legs are a little stiff. Then the following day arrives and the stairs suddenly feel much steeper than they did yesterday.

Sitting down becomes a carefully controlled manoeuvre. Your normal walk feels less normal. Muscles you barely noticed during the workout are now making themselves known.

Welcome to delayed onset muscle soreness, better known as DOMS. It is one of the most familiar experiences in exercise and one of the most misunderstood.

 

What Is DOMS?

DOMS stands for delayed onset muscle soreness. The word delayed matters because this type of soreness usually does not peak while you are exercising. It develops after the activity has finished and can become more noticeable over the following day or two.

DOMS is especially common after starting resistance training, returning to running after a break, taking on a long or unfamiliar hike, introducing new exercises or suddenly increasing training volume or intensity.

That delayed pattern is different from the immediate burning, fatigue or effort you may feel during exercise. DOMS is what appears later, once the workout is finished and the body has begun responding to the challenge.

Why Are You More Sore on Day Two?

This is one of the most common questions about post-workout soreness. If the workout caused the soreness, why did it not hurt immediately?

The reason is that DOMS is not simply the sensation of muscle fibres being stressed during exercise. Exercise provides the initial stimulus, then a sequence of biological responses unfolds afterwards.

Those responses involve mechanical stress, cellular signalling, inflammatory and repair-related processes, changes in local tissue sensitivity and the nervous system's perception of those signals. They take time to develop, which is why soreness may feel worse the next day or the day after.

Lactic Acid Is Not the Cause

For years, DOMS was blamed on lactic acid. The explanation has stuck around, but it is not correct.

During demanding exercise, lactate can rise as part of normal energy metabolism. But lactate does not remain trapped in muscles for two or three days causing soreness. It is processed relatively quickly after exercise.

So Wednesday's sore legs are not caused by Monday's lactate. DOMS is associated with a different sequence of mechanical, cellular, inflammatory and sensory responses.

 

Why Eccentric Exercise Can Make You So Sore

Muscles can produce force while shortening, staying roughly the same length or lengthening under load. That last type is called an eccentric contraction.

Examples include lowering a dumbbell slowly, walking downstairs, running downhill or controlling the downward phase of a squat. These movements can be particularly associated with DOMS when your body is not accustomed to them.

This explains why a downhill hike can leave your thighs unexpectedly sore even though the downhill section felt easier than climbing up. Cardiovascularly, downhill may feel easier. Mechanically, your quadriceps may have a different opinion the next day.

 

What Is Actually Happening Inside Sore Muscles?

DOMS can feel like simple muscle damage, but the biology is more sophisticated than that. When muscle experiences unfamiliar or demanding mechanical loading, microscopic disruption and cellular signalling can occur within the exercised tissue and its supporting structures.

That does not mean you have suffered a major tear. Normal training can create a manageable stimulus that the body is designed to respond to. The response involves repair, remodelling and communication between muscle cells, immune activity and sensory nerves.

Inflammation is part of the story, but that does not automatically mean something has gone wrong. Inflammation is also a normal form of biological communication involved in repair and remodelling.

The sensation of soreness also involves the nervous system. As the local environment around the exercised tissue changes, sensory pathways may become more sensitive. Movements that normally feel ordinary, such as sitting into a chair or walking downstairs, can temporarily feel uncomfortable.

DOMS Is Not a Scorecard for a Good Workout

Many people use soreness as a measurement of workout quality. They think that if they are very sore, the workout must have been excellent. If they are not sore, perhaps they did not work hard enough.

That is not how training works. DOMS is strongly influenced by novelty. An unfamiliar exercise can make you very sore even when the workout was not especially productive. Meanwhile, someone who has trained consistently for years may complete an excellent workout and experience very little soreness.

Severe soreness is not required for progress. In fact, if a workout leaves you so sore that you cannot train appropriately for several days, excessive soreness may interfere with consistency.

Your Body Learns: The Repeated-Bout Effect

One of the most interesting features of DOMS is that the body learns. Perform the same type of exercise again after recovering and it will often produce less soreness. Repeat it consistently and soreness may decrease further.

Researchers often call this the repeated-bout effect. The body has adapted to the challenge. The nervous system is more familiar with the movement. Muscles and connective tissues are better prepared for similar loading. The activity is no longer quite so surprising.

 

This is a helpful mental shift. The goal is not to keep shocking the body into soreness. The goal is to build capacity so the body can tolerate, recover from and progress the activities you ask of it.

Why Beginners Often Feel More Sore

DOMS is especially relevant for people starting or returning to exercise. Their bodies are encountering movements they may not have performed for months or years, so ordinary exercises can represent substantial new loading.

Someone completing their first squat session does not need to train like an elite athlete to become sore. For their current physiology, the movement is already a new challenge.

This is why beginning gradually matters. The first workout should help someone think, I can do this again, not never again.

What Actually Helps DOMS?

Once you are sore, the obvious question is how to make it go away. Online advice often promises quick fixes: ice baths, stretching, massage guns, foam rollers, supplements, compression garments, special drinks and saunas.

Some strategies may help people feel better in certain situations. But there is no single treatment that instantly switches DOMS off. DOMS generally improves as the body's normal recovery response progresses.

Should You Exercise While Sore?

It depends on the soreness and the activity planned. Mild soreness may not prevent comfortable movement, active recovery or training another area. Significant soreness can temporarily affect strength, range of motion, coordination and technique.

If you are so sore that your movement changes substantially, another demanding session targeting the same muscles may not be the smartest choice. Options include gentle activity, training a different area, reducing intensity or taking additional recovery time.

 

Nutrition, Protein and Hydration

Recovery requires adequate nourishment. Balanced meals provide protein, carbohydrate, dietary fats, vitamins, minerals and fluids.

Protein supplies amino acids used throughout the body and contributes to the maintenance and growth of muscle mass. Carbohydrates can help replenish glycogen used during exercise. Fluids support normal physiological function, especially after sweating.

Protein does not instantly erase soreness. Water does not flush DOMS away. Nutrition and hydration are part of the environment that supports normal recovery.

Where Bone Broth Fits

Bone broth can fit within a whole-food recovery pattern. Depending on the product and serving, it can contribute protein, collagen-derived amino acids and fluid when prepared as broth.

It can be used warm after training, in soups, in rice or grains, in slow-cooked dishes or as part of a balanced recovery meal. But bone broth should not be presented as a cure for DOMS.

Its strongest role is practical: it helps make nourishing food easier to prepare and enjoy while sitting alongside the fundamentals of sleep, appropriate training, recovery time, dietary variety and hydration.

When Soreness May Not Be DOMS

Typical DOMS generally develops gradually after exercise, affects muscles that were heavily or unusually used, feels like tenderness or stiffness and improves progressively over several days.

Not every post-exercise pain should be labelled DOMS. Sudden or severe pain during exercise, substantial swelling, significant bruising, marked weakness, major loss of normal function or pain that continues worsening deserves more caution.

Severe muscle pain or weakness accompanied by dark or cola-coloured urine after strenuous exercise requires urgent medical attention.

Frequently Asked Questions

What is DOMS?

DOMS stands for delayed onset muscle soreness. It is post-exercise soreness that develops after unfamiliar or demanding activity, often becoming more noticeable 24-72 hours later.

Why am I more sore the day after exercise?

DOMS is delayed because the biological response to exercise unfolds after the workout. Mechanical stress, cellular signalling, inflammatory processes and sensory changes develop over time.

Is DOMS caused by lactic acid?

No. Lactate is processed relatively quickly after exercise and does not stay trapped in muscles for days. DOMS is linked with the body's response to unfamiliar or demanding mechanical loading.

Does soreness mean I had a good workout?

Not necessarily. Soreness is strongly influenced by novelty and eccentric loading. A productive workout does not need to cause severe soreness.

Should I stretch sore muscles?

Gentle stretching may feel pleasant, but it is not a guaranteed way to prevent or eliminate DOMS. Comfortable movement is usually a better guiding principle than aggressive stretching.

Can I exercise with DOMS?

Mild soreness may allow gentle movement or an appropriate session. Significant soreness that changes technique or normal movement suggests more caution.

What helps DOMS?

Time, gentle movement, sleep, balanced nutrition, hydration and sensible training progression can all support the recovery environment. No single strategy instantly switches DOMS off.

Where does bone broth fit?

Bone broth can contribute protein, collagen-derived amino acids and fluid as part of a broader recovery-supportive diet, but it is not a cure for DOMS.

Summary

DOMS is uncomfortable because you can feel it. But beneath that temporary discomfort is a more interesting story: the body is learning from a new physical challenge.

A movement that was unfamiliar becomes familiar. The nervous system coordinates it better. Muscles and connective tissues become more accustomed to the loading. The same activity often causes less soreness over time.

That is adaptation. And adaptation, not soreness, is the reason we train.

The next time you are carefully lowering yourself onto a chair two days after returning to exercise, remember that soreness is not the prize. The prize is what happens after it: you recover, you return and your body becomes more capable than it was before.

Selected Research

Delayed onset muscle soreness is commonly associated with unfamiliar or demanding exercise, especially movements involving eccentric muscle actions.

DOMS is not caused by lactate remaining trapped in muscle for several days.

The repeated-bout effect helps explain why a familiar exercise often causes less soreness after the body has adapted to it.
