THE STRONG SERIES #11: Does Being Sore Mean Your Workout Worked?

November 10, 2026

We've all had that leg day. You leave the gym feeling pretty good about yourself, only to wake up two mornings later wondering how you're supposed to sit down, walk upstairs or get out of bed without looking like you've forgotten how your legs work.

And somehow, there's a little satisfaction in it. A sore booty, aching quads and that familiar post-workout shuffle can feel like proof that you've put in the work.

But does being sore actually mean your workout was effective?

Not necessarily.

Muscle soreness is a normal part of strength training, but it isn't a reliable measure of muscle growth or strength gains. And while we all love that feeling of knowing we've had a good session, chasing soreness isn't always the best way to make progress.

Let's get into it.

What Actually Causes Muscle Soreness?

That delayed soreness you feel after a workout is known as Delayed Onset Muscle Soreness (DOMS). It typically develops several hours after exercise and is often most noticeable between 24 and 72 hours later.

It's especially common after trying a new exercise, increasing your training intensity or doing movements that involve eccentric contractions. That's when your muscles lengthen while under tension, like lowering into a squat or bringing a dumbbell back down during a bicep curl.

These movements can create small amounts of exercise-induced muscle damage, triggering processes involved in inflammation and repair. That's part of why your muscles can feel tender or stiff a day or two later.

And just to clear up a common gym myth: soreness isn't caused by lactic acid building up in your muscles. Lactate is cleared relatively quickly after exercise, so it isn't responsible for that two-day-later struggle to get off the couch.

Does More Soreness Mean More Muscle Growth?

Here's where things get interesting.

Building muscle is influenced by several factors, including mechanical tension, sufficient training volume and progressive overload. In simple terms, you need to challenge your muscles consistently and gradually give them a reason to adapt.

Muscle damage can happen during resistance training, but it isn't something you need to maximize to see results. Research suggests that experiencing more muscle damage or soreness doesn't necessarily translate into greater muscle growth.

In fact, constantly pushing yourself to the point of extreme soreness can make it harder to train consistently. If your legs are still recovering from Monday's workout by Thursday, it might affect how well you perform in your next session.

The goal isn't to leave every workout barely able to walk. It's to stimulate your muscles, give them time to recover and keep building on your progress.

Why You're Less Sore as You Get Stronger

Ever notice how a workout that absolutely destroyed you the first time around barely leaves you sore a few weeks later?

There's actually a reason for that.

It's called the repeated bout effect. When you expose your muscles to a particular exercise, they gradually adapt to it. Repeating similar movements often results in less muscle damage and soreness over time.

This is why beginners, or anyone introducing new exercises into their routine, may experience more DOMS than someone who has been following a consistent program.

And no, it doesn't mean your workouts have stopped working.

Your body is simply getting better at handling the demands you're placing on it. That's a good thing. Less soreness can mean you're adapting, not that you're suddenly doing something wrong.

Can You Have a Great Workout Without Being Sore?

Absolutely. And honestly, that's often the goal.

A productive workout doesn't have to leave you reaching for the stairs like they're your biggest enemy. Many effective strength-training sessions cause very little soreness, especially once your body becomes familiar with the movements.

Instead of judging your workout by how much it hurts the next day, pay attention to other signs of progress:

You're gradually lifting heavier weights or completing more reps.
Your technique is becoming more controlled and consistent.
You're maintaining good performance throughout your sets.
You're recovering well enough to show up for your next session.
You're staying consistent with your training.

These are much more meaningful indicators that your program is working.

So, Should You Be Concerned About Soreness?

A little soreness is completely normal, especially after a new exercise or a particularly challenging session. But if it's regularly interfering with your workouts, significantly limiting your movement or lasting longer than expected, it may be worth reassessing your training volume, exercise selection and recovery.

Sharp or severe pain, significant swelling or unusual weakness shouldn't automatically be written off as normal muscle soreness. Those symptoms deserve medical attention.

And remember, recovery is part of the process. Getting enough sleep, eating enough to support your training and giving your muscles time to recover all matter just as much as what happens in the gym.
