The REAL Reason Lunges = Knee Pain

I hear it all the time…
“I can’t do lunges because they hurt my knees”
But, think of so many movements we do outside of ‘the gym‘ like walking up and down stairs, getting in and out of our car, bending down to pick up a set of keys off the floor, running–well–you get the picture.
What do these movements have to do with lunges and knee pain?
Everything!
These movements and many others we do all the time are performed in a single-leg dominant environment and a necessary part of our everyday lives…
…think about if you had to squat down in a traditional squat position EVERY time you bent down.
You’d have a pretty tough time getting in and out of your car, kneeling down and walking stairs.
And, you’d have to forget playing most sports, right? 
Therefore, avoiding these movements rarely fixes a problem such as knee pain.
The truth is that lunging and squatting are NOT bad for your knees as their reputation suggests.
What’s ‘bad‘ is lacking the conditioning to perform lunges and squats safely and effectively so they don’t injure your knees.
Eliminating chronic knee pain and knee injuries requires an ability to perform every day functional movements efficiently.
This is best achieved through training. But, it takes more than just doing “functional” exercises on a balance pad or stability ball.
In most cases, knee pain from lunges doesn’t happen because someone has “weak knees”, “bum knees”, “arthritis” and it’s not because of “old-age” either.
The REAL reason lunges (and squats) often cause knee pain is due to muscular imbalances related to the quadriceps and hip flexors.
But, aren’t we supposed to feel the quads during leg exercises?
Well, it’s a little more complex than an either-or answer can provide…Allow me to explain a bit more about what I mean.
I’ve discovered that most people are what I call ‘quad-dominant’ meaning that they have developed most of their lower extremity strength in the quadriceps.
Now, these individuals often also have tight or dominant hip flexors as well.
And, this quad-dominance creates an imbalance of the lower extremities during functional movements like squatting and lunging because exclusively using the quadriceps results in a ‘forward’ pulling at the hip.
Now, you can’t actually see it happening but what you’ll notice when you watch someone do a squat or lunge is their hips and knees will move a bit forward.
And, if you ask them where they feel it 9 times out of 10 they’ll say in the quadriceps.
This quad-dominance and forward motion shifts the center of gravity and INCREASES stress to the knees.
This is the #1 reason why lunges and squats cause problems to the knees, hips, ankles and lower back too. But, it’s easy to fix once you’ve performed a proper lower body exercise assessment and identified the weak links.
Speaking of identifying weak links in the lower extremities, I was recently a featured presenter for Muscle Imbalances Revealed where I and 6 other presenters shared our best training tips and secrets for overcoming injuries to the lower body.
It’s packed full of ‘how-to‘ info on everything you need to know to correct the muscle imbalances that are responsible for most injuries to the knees and lower body.
However, if you’re looking for an effective exercise and conditioning solution you can use right away to overcome knee pain fast then you may want to check out The Knee Injury Solution by Rick Kaselj.







Great article. I look forward to receiving your updates and products

I have question regarding posterior tilt of hip during squats. When I lower below quarter of squat, my hip is starting o tilt posteriorly. I know that I was quad dominant for most of my life (skiing, martial arts, biking…) but after a year of stretching my quads and ilio-psoas m. and foam rolling and all that It seems that postrior tilt is not going away. I am doing mostly hip dominant exe now (DL, glute bridge, cook hip lifts …) to compensate for this. Hope it’ll work in near future.
Do you have answer to this?
Take care
Robert

Thanks for the comment Jo

This is a great question Robert and yes I have an answer. The posterior tilting is most likely a hamstring dominance or tightness issue versus just a quad issue.
In other words, you’re either overcompensating with the hamstrings or they’re just plain tight at the attachment to the ischial tuberosity (just under your glute max). Or perhaps a little of both.
When you do your glute bridges make sure you aren’t ‘rolling’ your hips off the floor. If you hold the bridge position for 60 seconds notice where you feel it.
You might feel quite a bit of the hamstrings working.
Thanks for the question Robert and keep me posted on your results ok?

Thanks Kevin for an answer.
Reply to your answer is: I don’t role my hips in glute bridges ( at least what I saw on camera) but movement is small and I almost entirely straighten my hips and don’t feel it in lower back when I do them for reps aor iso hold. Also for twnty years in martial arts I developed quite good flexibilty in hamstrings (only one pull
) Maybe you can tell me what is good forward flexing position with straight legs and stiff low back?
If this is hamstring dominance issue than maybe is because the last two years before this one I entierly perform dead lifts. Which maybe lead to stiff hams. But I stretch a lot (static and dynamic)
Thanks for a reply agagin and looking forward to order your ebook.
Take care and all the best

That’s cool that you put yourself on camera to observe..Great idea Robert! I’ll have to do that myself.
Yeah, you’re hamstrings don’t necessarily need to be tight, they can be dominant meaning they just do most of the work during hip extension exercises.
When you do a bridge hold it for 1 minute and notice where you feel it working most…This will tell you a lot.
And, deadlifts are an awesome exercise but you’re right that overdoing them can lead to dominant hamstrings.
I hope this helps…Keep me posted Robert and thanks for your comments,
Kevin
Wow this is a great resource.. I’m enjoying it.. good article
Hi Kevin
Thanks for reply Today I tested again in glute bridge iso hold for 1 minute. I mostly feel in my glute, but also in hamstrings just bellow the glute (like you wrote) Also i notice for a firts time that I can’t stretch/extend my hip flexors to straight level. But on Thomas test I am negative on both sides, I go bellow horizontal with my thigh.
Also I think that is important to know that I have very big and I mean veryyyy big quadriceps mostly of my genetics and skiing and martial arts thats why I belived that I am mostl quad dominant so because that I need much more hip extensions exercises.
Any suggestions on this?
Thanks and I love your work
Robert
i found your site to be most relevant to the information i have been searching for? there isnt a lot of sites on the net which contain excellent information like yours..
thankyou for providing me with the info..
great site and great info
thanks
