5 Reasons Your Knees Hurt Squatting & How To INSTANTLY Fix It

knees hurt squatting

If your knees hurt squatting it doesn’t mean that squats are a bad exercise.

In fact, squats and lunges have gotten such a bad reputation for causing knee, hip and lower back problems.

That’s like saying McDonald’s food kills people. <==The food can’t kill ya if you don’t stick in your mouth

It’s not squats that cause pain and injuries; it’s how the squat is performed that’s the problem.

Seriously, who ever heard of anyone blowing out an ACL while sitting down to take a dump?

The truth is that the squat is a poorly understood exercise.

Squats are an excellent exercise for strengthening the hips and knees but, unfortunately, most people do not perform them correctly even though think they do.

There are 5 common mistakes I have identified in individuals whose knees hurt squatting.

Just one of these mistakes is enough to feel knee pain during squats:

1. Weight on the toes: This happens a lot when using too much weight which tends to pull your body too far forward. Other times it’s simply a lack of awareness of how to distribute one’s body weight.

2. Hips & knees move forward while squatting: This is a huge reason most people’s knees hurt squatting and an example of poor movement mechanics and/or tight hamstrings.

3. Thighs and lower back muscles doing most of the work: This happens when the core, glutes and hamstrings are weak. When you lack proper core and hip strength muscle imbalances often result in the quadriceps and lower back over working. This is one of the main reasons for knee pain during squatting.

4. Abs and hips are weak: These muscles need to be properly strengthened in order to eliminate knee and lower back pain.

5. Trunk collapses forward: This is a sure-fire sign of weak abs and glutes.

It’s important to understand that each of the above are caused by muscle imbalances that cause pain and injuries to areas of the body like the knees, back, shoulders, neck, ankles and feet.

In other words, movements like squatting and lunging are not bad for your knees and they don’t cause injuries.

Muscle imbalances are the real problem.

If you don’t address muscle imbalances your knees hurt squatting, lunging, running and your pain will get worse over time.

    I have watched this video yesterday, and it revolutionized the way I do squats. I have recently included squats in my work-out, and my knees were hurting even with very light weight. Watching your video helped me understand that it is not the quads that are the primary working muscles, but rather the glutes and hamstrings. The way you demonstrate the hips forward movement has helped a lot. Thank you!

    hi Kevin

    My problem with squats is that I am physically unable to come down very far at all if I keep my trunk almost upright. Reading point 5 above, I think my core is quite strong so I am guessing it is more to do with quads/lower back – are there any exercises/stretches I can do to improve this?

    By the way, I have been watching your videos etc for a few months now and they are really helpful so thank you!


  5. Kevin YatesNo Gravatar

    It’s not so much to do them completely upright with your trunk just not excessively forward…In your case if it’s quad and low back compensation then stretches will do very little if anything to correct it…instead it may be a case of your core and hips not being strong enough in the extended position so you’d need core strength in the role of stabilization with your trunk in more upright and extended position

    I don’t know. I tried squatting with my feet straight ahead more or less, and what it does is my hips get pulled down at the bottom pretty hard ie I round.

    Good video. As soon as my knee pain goes down I will try doing it the right way. Also I have read on many websites that if you got knock knees its better to do the squad with feet pointing outward and knees pointing the same direction. What would you suggest in case of knock knees?


  10. Kevin YatesNo Gravatar
    2 years ago

    I’ve discovered that knock knees have more to do with poor core and hip strength (and compensation patterns) than with the knees themselves.

    The feet turned out gives you stability through leverage but not through muscle contraction. Not to say you cannot perform a squat properly with feet turned out but you shouldn’t have to rely on this position to perform a squat safely.

    As your core and hips become stronger the knees will not ‘knock’.


  11. Kevin YatesNo Gravatar

    Check your hips Felicia. Stand with your side facing a full length mirror. Watch your hips. Do they move forward upon the initial decent into a squat? If so, drive your hips back keeping your weight on your midfoot/heels.

    I have cronic low back pain from tissue damage. And two knees that “crunch” when I squat or do stairs, they don’t hurt, I just don’t want to make them hurt. My question is this. ..is there any move I can make so I CAN do squats? I think I’d like the result of doing them. Thanks!


  13. Kevin YatesNo Gravatar

    I usually don’t worry about ‘noise’ if it doesn’t cause pain.

    Do your needs move forward, inward or outward as you descend into your squat?

    I am very glad I found this video because I did pay good money for a personal trainer (only to injure myself) who told me the EXACT opposite!

    I did appreciate the trainer telling me that squats were one of the best exercises (I did not know that and I am glad this video is consistent).

    BUT, the trainer had me working quads over and over again, even when I told him my knees were hurting! He said if I couldn’t unsupported squats then spread 30 mins on the leg extension machines or leg press machines. Those machines, while I was able to lift lots of weight, only hurt my knees more.

    I burned out! I quit going to the gym. I thought I had seriously had hurt myself beyond repair.

    This is a great video to refer to when I want to SLOWLY re-introduce squats into the workout.

    Thanks for clearing up the expensive misconceptions I paid for earlier.


  16. Kevin YatesNo Gravatar
    2 years ago

    What you’re describing is actually very common and it happens in more than just personal training.

    I’ve seen many, many physical therapists having their patients doing the same thing…strengthening the quads without ever looking into the fact that our bodies are not meant to work in isolation.

    They are a functional unit designed to use many muscles to accomplish movements.

    One quick suggestion that may help you out…

    …If you’re not yet able to squat you can try using a cable machine and perform bent over rows. Just line the cable in front of you rather than toward the floor so it moves in a straight line toward you. That way it allows you to squat to your depth (whatever is comfortable for you) and conditions you into the squat pattern.

    You can progress your depth as you’re able.

    I’m happy to know my video helped you Mandi :)

    I’ve been trying to work around knee pain for several years. Squatting heavy with poor form damaged them and I only made it worse by continuing to put pressure on my knees with a variety of activities. Nothing helped. Trainers and gym members told me that my form was good, so I thought that it was just my anatomy that wasn’t conducive to squatting. Xray and MRI showed no damage but the pain continued so I gave up squatting with weights, only doing bodyweight squats until they began to hurt.

    Just came across this video and tried it on a whim. I wasn’t expecting anything, but am now squatting without any pain besides normal soreness. No weights yet but this is already a remarkable difference. Thank you so much!

    Having minor muscle pain is normal but having joint pain is not something you should be feeling.

    The knee pain can be fixed by correcting your technique.


  26. Kevin YatesNo Gravatar

    Also, make sure you’re not doing squat workouts everyday. Gotta give your legs time to recover.


  27. Kevin YatesNo Gravatar

    Hey Alina, I just replied to your other question but for now take some time off to give your knees a rest.

    After the pain resolves itself try squatting with just your own body weight so you can master the technique.

    If you have trouble then try squatting while holding a support like a pole, light weight dowel or something similar that’s stable.

    It’s not the exercise that’s hurting your knees. It’s just that you’ve gotta get the technique down with the right muscles working.

    Once you get it down you won’t feel pain in your knees.

    Hope this helps :)

  31. HankNo Gravatar

    Thanks for the informative video Mr.Yates.
    I have been having terrible knee pain the last few months. It all began when I started the Madcow 5×5 program.
    I really, REALLY like that program, but since beginning my knees have taken a major hit.
    Just bending down to pick something up sends waves of sharp knife-stabbing pain to my knee’s.
    I had basically given up on doing squats. The whole purpose of working out is so I can remain in good shape to play with my kids and grandkids. It seems like it’s doing the opposite.

    I’m going to try your recommendations and see if it helps.
    One question I have is, what is your opinion on ATG (arse-to-grass) squats?
    I’ve enjoyed that form more than parallel but want to make sure it’s safe and the proper way of squatting.

    Thank-you!
    Hank

    Very helpful. I’ve been doing daily bodyweight squats for about two months now. Yesterday, I had some discomfort in my right knee while squatting. After the workout, it stopped but started again in today’s session. I think it may have something to do with my wide stance and the fact that I try to keep my trunk as vertical as possible. Or maybe the reps are too high (80)?

    I only have pain right beside my knee’s on the inside when I squat. If I bend at work, run or bike I have no issues. It’s only while I do squats any clue what I might be doing wrong?


  36. Kevin YatesNo Gravatar

    Hey Sarah,

    Sometimes it can just be an issue of over-thinking it too much. I used to have a couple clients who had the same type of issue. But, when they tried to do squats they got all caught up in over-thinking it and couldn’t do them.

    Try getting a bench and straddle it (one leg on each side) then just sit down as you would at work and stand back up.

    Don’t think about it but just do it and see what happens.

    Hi Kevin,

    I started doing squats 3 months ago and developed knee pain so I put it on hold. I was doing feet pointed out so will try your style to see how it goes.
    My question is this: I am 6’8″ so obviously have long legs and trunk. Are there any adjustments I need to make for being so tall or do I just follow the video as outlined?


  38. HeatherNo Gravatar

    Hi Kevin,

    I have knee pain already (outside of just doing squats). It occurs primarily when I go up OR down stairs, and when I am getting up out of a chair. I weigh way too much and I know it, and I have never had knee pain before a couple years ago but I’ve had it ever since.

    I have knock knees too, but I can’t see how my knees would ever not-knock (as you stated in an earlier reply) because if I extend my leg straight from a sitting position, my leg angles out from my knee down. I only mention it because I don’t know if it matters.

    The thing is, I just attempted a squat the way you said and both knees hurt pretty intensely when I was only a slight way down. I probably do not have good core strength. I have been going to the gym lately and the only thing that seems to work well is the individual machines because anything else hurts my knees. Even the leg press hurts my knees at approx 100+ lbs but it is a tolerable pain level while I am doing it.

    My question, even in proper form, is a squat something I should attempt at all or do I need to wait? I don’t know if my knee pain is caused solely by the weight or something else (my knees make sounds too, though it doesn’t *always* result in pain). If you do it in proper form but other body involved muscles are weak, will that still cause pain?

    hi , i was doing squat yesterday and had tremendous pain in my knees just because i have made mistake that you have mentioned in video. now i do not know what to do. should i relax for few days or continue workout. as my instructor say that yest i had done leg exercise and that the reason for knee pain.


  40. Kevin YatesNo Gravatar
    11 months ago

    muscle pain and joint pain are very different. if you feel pain in your knee joints than it’s not just muscle soreness. it’s a warning that something is wrong. you can try the suggestions in my video to correct your squat. if your knees feel better as you perform the exercise then you should be ok to keep doing it. if your knees feel worse than rest up until the pain goes away and try again. by the way, any instructor that tells you joint pain is just from doing exercise is someone i would not want to have train me.


  41. Kevin YatesNo Gravatar
    11 months ago

    good question and here’s the thing…

    …yes, you do need to squat just because so much of what you do outside of the gym and in everyday life involves squatting. sitting down, getting in and out of your car, getting in and out of bed, bending down around the house or at work, even going to the bathroom πŸ˜‰

    my point is that if you don’t correct it then squatting will continue to hurt your knees.

    in your situation there’s 3 issues that are likely causing your knee pain:

    1) a forward tilting of your pelvis (a.k.a ‘anterior pelvic tilt’) contributes to ‘knock knees’ which then causes

    2) core weakness particularly of your lower abs which help keep your pelvis in neutral alignment

    3) weak glutes (glute maximus and glute minimus) which are the muscles that control squatting and going up and down stairs. basically your glutes are designed to do the majority of the work and when they’re weak it causes more stress to your knees as they take the brunt of the force

    so to correct this I would first address the core which will put everything in alignment so you can then train the glutes.

    get yourself aligned using floor based exercises like I show in some of my videos on this blog and also in my program ‘The Muscle Imbalance Solution’ which I originally wrote for personal trainers however it has helped many people who aren’t trainers get rid of nagging pain and injuries.

    once you get to where you’re doing things right on the floor then work your way to standing exercises.

    hope this helps :)


  42. Kevin YatesNo Gravatar

    Hey Brett,

    I’ve experimented with squatting over the last year or so and I’m finding that a lot depends on your hip structure. However, try squatting the way I suggest and see if that fixes your pain. If not, just squat down naturally as if you were a caveman telling a story at a campfire. Lame example I know but it’s all I can think of right now πŸ˜‰

    Anyway, allow your feet to go where they naturally feel comfortable including the width of your stance. Rock yourself around in this bottom position. You’re looking for what feels comfortable and natural for you.

    Once you have it stand up without moving your feet.

    Notice if there’s any significant differences in foot position or leg position between right and left sides. If not, then try squatting from there and see how it feels. You should have no pain if everything’s good.

    If you’ve got some noticeable differences then it’s suggestive of muscular imbalances that need to be addressed at a deeper level than I can give you here but I do have in my program ‘The Muscle Imbalance Solution’. Although I wrote it for personal trainers it’s helped many people who are not trainers to get rid of their pain and injuries: http://functionaltrainingcoach.com/muscleimbalancesolution

    Hey Kevin,

    I had given up squatting at the gym because of chronic knee pain. After watching your video on keeping the feet parallel instead of splayed out to the sides, I decided to give it a try because what did I have to lose? Today I did 3 sets of 6 front squats with a light barbell…and had no pain at all. Wow! Will keeping the feet parallel also work for back squats as I go heavier? I’m very limber and have no problem doing a full squat as long as my knees don’t hurt.

    THANK YOU very much for resuscitating my squats. It means a LOT to me!

I used to get this sharp pain in the middle-outside part of my knee but this really seemed to clear things up. I was wondering: do the same principles apply when you are squatting with heavy loads? I want to make sure before I max again, and so that when I do, it is painless.

    Squats aren’t supposed to hurt but yes, unfortunately they do for a LOT of people.

    Not because they’re a bad exercise but because most people aren’t taught how to squat properly.
