Knee Pain While Squatting: Causes + Fixes

Squats are one of the most useful exercises for building strength in your legs and improving how you move. But if you experience knee pain while squatting, it can be frustrating, especially if you enjoy working out, playing sports, running, or simply want to stay active.

The good news is that knee pain during a squat doesn't necessarily mean you've damaged your knee or that you need to stop exercising altogether. Instead, knee pain is often a sign that something about the movement, your current workload, or your body's ability to tolerate that workload needs to be addressed.

Let's look at some common causes, and what you can do about them.

Why Does My Knee Hurt When I Squat?

There isn't one single cause of knee pain during squatting. Several factors can contribute, and sometimes more than one is involved.

1. You're Doing More Than Your Knee Is Used To

One of the most common reasons for pain is simply a sudden increase in training load. Maybe you've started lifting heavier, increased your running mileage, added more workouts, or returned to exercise after some time off.

Your muscles, tendons, and joints adapt to the demands placed on them. If the demands increase faster than your body can adapt, pain can develop. This doesn't necessarily mean you've "hurt" your knee. It may simply mean that your current workload is exceeding your knee's capacity.

The fix: Temporarily reduce the amount of weight, repetitions, or frequency that aggravates your symptoms, then gradually build back up as your tolerance improves.

2. Your Squat Technique May Need Some Adjustment

There isn't one perfect way for everyone to squat.

Your anatomy, mobility, strength, training history, and the type of squat you're performing all influence how you move.

However, certain movement strategies can increase the demands placed on the knee. For example, if you have limited ankle mobility, you may compensate elsewhere during the squat. This doesn't mean that your knees should never move past your toes. That's a common misconception.

The fix: Instead of trying to force yourself into a "perfect" squat position, experiment with small changes such as reducing squat depth, adjusting your stance, using a heel elevation, or changing the type of squat you're performing.

3. Your Hips, Ankles, or Other Areas May Be Contributing

Your knee doesn't work in isolation.

Squatting requires coordinated movement from your ankles, knees, hips, and trunk. If one area has limited mobility or strength, another area may have to compensate.

For example, restricted ankle dorsiflexion can change squat mechanics. Similarly, inadequate hip strength or control may affect how the leg moves during a squat.

This doesn't mean that your knee pain is necessarily caused by a "weak" muscle or a "tight" muscle. Human movement is more complicated than that.

The fix: Rather than focusing exclusively on the painful knee, look at the entire movement.

4. Your Knee May Simply Be Sensitive Right Now

Pain doesn't always equal tissue damage.

Pain is a protective experience influenced by many factors, including physical stress, sleep, stress levels, previous injuries, and how quickly your activity level has changed.

This is particularly important for people who have been dealing with knee pain for a while. If every painful sensation makes you stop moving completely, you may gradually lose strength and confidence in the movement.

The fix: Find a level of activity that your knee can tolerate and gradually increase it.

What Should You Do If Squats Hurt?

You don't necessarily have to stop squatting. Instead, try modifying the exercise.

Reduce the Load

If your normal squat is causing pain, decrease the weight. You may be able to perform a lighter squat comfortably while still getting a useful training stimulus.

Reduce the Depth

You don't have to squat as deeply as possible. Start with a depth that feels comfortable and gradually work toward greater depth as your symptoms allow.

Change the Exercise

Try a variation that is more comfortable, such as:

• Box squats

• Goblet squats

• Split squats

• Step-ups

• Leg presses

• Sit-to-stands

The goal isn't to find the "perfect" exercise. It's to find a variation that allows you to train while gradually improving your capacity.

Build Strength Gradually

Long-term improvement usually requires more than simply avoiding whatever hurts.

Progressive strengthening can help your muscles and tissues become better prepared to handle the demands of your daily life, exercise, and sports.

The key is progressive.

Doing too much too quickly can keep symptoms irritated, while doing too little may not provide enough stimulus for adaptation.

When Should You Get Your Knee Pain Evaluated?

Occasional mild discomfort during exercise isn't necessarily an emergency, but persistent or worsening pain deserves attention.

It's particularly important to have your knee evaluated if you experience:

• Significant swelling

• Locking or catching

• The knee giving way

• A significant injury or trauma

• Inability to bear weight

• Severe or worsening pain

• Symptoms that aren't improving despite modifying your activity

An evaluation can help determine whether the problem is primarily related to training load, movement, strength, mobility, or something that requires further evaluation.

The Bottom Line

Knee pain while squatting doesn't automatically mean you need to stop squatting.

The better question is:

"Why is my knee having trouble tolerating this particular movement or workload?"

Rather than chasing a perfect squat technique or avoiding exercise indefinitely, focus on understanding what your body is currently capable of handling and gradually improving that capacity.

If you've tried changing your squat, reducing your workload, or resting but your knee pain continues, a thorough movement evaluation can help identify factors that may be contributing to your symptoms.

At Alameda Chiropractic & Ergonomics, I take a movement-focused approach to musculoskeletal pain. That means looking beyond the painful area and considering how strength, mobility, movement patterns, training load, and your individual goals may be contributing to the problem.

The goal isn't simply to make your knee feel better today.

It's to help you build a knee, and a body, that is better prepared for the activities you want to keep doing.
