The 7 Best Squat Variations for Knee Pain (and How to Know Which One Is Right for You)

By Dr. Shari Miller, PT, DPT, OCS

"I stopped squatting because my knees hurt."

I hear this almost every week. And every week, I say the same thing: squatting isn't the problem. How you're squatting might be.

Here's the truth that a lot of people miss, your body needs to squat. Sitting down, standing up, picking something up off the floor, getting on and off the toilet. That's all a squat. It's one of the 6 foundational movements your body needs to function in daily life. If you can't squat, everyday tasks get harder. And avoiding the movement altogether doesn't make your knee better, it makes the muscles weaker, which makes the knee worse.

So the goal isn't to stop squatting. It's to find the squat that works for your body right now and build from there.

Why Squats Hurt Your Knees (It's Usually Not What You Think)

Before we get to the variations, let's talk about what's actually happening when your knee hurts during a squat. Because understanding the why changes everything.

When you squat, your knee joint bends and the kneecap (patella) slides in a groove on your thighbone. If everything is balanced, strong quads, strong glutes, mobile ankles, mobile hips, that kneecap tracks smoothly and the load distributes evenly.

But here's what I see constantly: the outer glute isn't doing its job, so the knee caves inward. Or the ankle is stiff, so the shin can't move the way it needs to, and the knee takes all the stress. Or the quads are weak, so instead of the muscles absorbing the load, the joint takes the hit.

When your knee caves in during a squat, that means the outer glute is not working to keep your leg in good alignment. So the knee moves in, the kneecap gets pulled off-track, and you get pain, usually right around or behind the kneecap.

This is fixable. It's not a life sentence. But it does mean you need to find a squat variation that lets you work within a pain-free range while we address the underlying issue.

The Rule Before We Start

All of these exercises should be relatively pain free. A little discomfort, like a muscle working hard or a stretch, I am okay with that. Sharp, stabbing pain? Stop. Reach out and let's figure out what's going on.

Start with the lower amount of reps first. Make sure you feel okay the next day. Then on the next workout you can increase the difficulty. Don't let a good day trick you into overdoing it.

The 7 Best Squat Variations for Knee Pain

1. Wall Squat (Wall Sit)

Why this works for knee pain: The wall supports your back, which forces you into better alignment and takes some of the load off your knees. It also limits how deep you go and depth is often where knee pain shows up.

How to do it: Stand with your back flat against a wall, feet about shoulder-width apart and roughly 18 inches away from the wall. Slide down until your thighs are at about a 45-degree angle (not a full 90, that's too deep to start). Hold for 10-15 seconds. Slide back up. Repeat 8-10 times.

The cue that matters: Make sure your knees are tracking over your second and third toes, not caving inward. If they're drifting in, squeeze your glutes. That's the muscle that's supposed to keep your knee in line.

2. Box Squat (or Chair Squat)

Why this works for knee pain: Having something behind you changes everything. It lets you sit your hips back which shifts the load off your knees and onto your posterior chain (glutes, hamstrings, lower back). It also gives you a built-in depth limiter so you don't go past the point where pain starts.

How to do it: Stand with a sturdy chair or box behind you. Feet shoulder-width apart. Push your hips back like you're reaching your butt for the chair. Lower until you lightly touch the seat, don't plop down. Pause for a second, then drive through your heels to stand back up. Start with 8-10 reps.

Dr. Shari tip: Start with a higher surface (like a dining chair or stool) and work your way down to a lower box as you get stronger. The height of the box controls how much your knee bends and that's how we manage your symptoms while building strength.

3. Goblet Squat

Why this works for knee pain: Holding a weight at your chest (a dumbbell or kettlebell) naturally shifts your center of gravity forward, which helps you stay more upright. Studies show that front-loaded squats create significantly less compression on the knees and lower back compared to back squats.

How to do it: Hold a dumbbell or kettlebell at chest height with both hands, elbows pointing down. Feet shoulder-width apart, toes turned out slightly (about 15-20 degrees). Push your hips back and down, keeping your chest tall. Go only as deep as is comfortable. Drive back up through your heels. Start with 8-10 reps with a light weight.

Why the weight actually helps: I know it seems counterintuitive adding weight when your knee hurts? But the counterbalance of the weight in front keeps your torso upright, which means your knees don't have to travel as far forward. Less forward knee travel = less kneecap compression = less pain.

4. Spanish Squat (Banded Squat)

Why this works for knee pain: This is one of my favorites for patellar tendon issues and general anterior knee pain. The band pulls your shin backward, which reduces the amount your knee has to translate forward. That posterior pull essentially deloads the front of the knee while still working the quads hard.

How to do it: Loop a heavy resistance band around a sturdy anchor at about knee height. Step into the band so it sits in the crease behind both knees. Walk back until there's tension. Stand with feet shoulder-width apart. Lean your torso back slightly and squat down, letting the band pull your shins vertical. You'll feel your quads working intensely. Hold for 20-30 seconds, or do 10-12 reps.

When to use this: If you feel pain specifically at the front of your knee around the kneecap or just below it in the tendon — this is the variation to try first. The band changes the mechanics in a way that often makes squatting pain-free immediately.

5. Sumo Squat (Wide Stance Squat)

Why this works for knee pain: A wider stance with toes turned out shifts the squat into more of a hip-dominant movement. That means your inner thighs (adductors) and glutes do more of the work, and the stress on your kneecap and patellar tendon decreases.

How to do it: Take a wide stance- wider than shoulder-width, toes pointed out at about 30 degrees. You can hold a dumbbell between your legs or use bodyweight. Push your hips back and down, keeping your knees tracking over your toes. Squeeze your glutes at the top. Start with 10-12 reps.

Who this is best for: If traditional squats bother you but you feel fine sitting in a wide stance (think: getting in and out of a car), this variation is worth trying. The wider base also makes it inherently more stable, which helps if balance is a concern.

6. Tempo Squat (Slow Eccentric Squat)

Why this works for knee pain: Slowing down the lowering phase of the squat does something powerful, it builds tendon tolerance. If your pain is related to a tendon issue (which is very common), slow eccentric loading is one of the most evidence-backed interventions available. It creates the structural changes in the tendon that help it adapt and get stronger.

How to do it: Using any squat variation from this list that is already comfortable for you, take 3-4 seconds to lower down. Pause for 1 second at the bottom. Stand up at normal speed. Start with 6-8 reps.

Why slow matters: Think of it like this, you wouldn't go from walking to sprinting without building up. Your tendons work the same way. Slow loading teaches the tissue to handle stress gradually. It's not sexy. It doesn't feel like a hard workout. But it's incredibly effective for knee pain.

7. Step-Ups

Why this works for knee pain: Step-ups are technically a single-leg squat pattern, and they're one of the most functional exercises you can do, because going up stairs, stepping over something, and getting in and out of a car are all step-up patterns. You also don't need heavy weight to get significant benefit, which means less overall stress on the joint.

How to do it: Find a step, box, or sturdy bench that's about mid-shin to knee height (start lower). Place one foot fully on the step. Press through the heel of the working leg to step up, bringing the other foot to the top. Slowly lower back down, controlling the descent. Do 8-10 reps per side.

The common mistake: Don't push off with the bottom foot. The working leg (the one on the step) should do the work. If you're cheating with the bottom foot, the step is too high. Lower it.

How to Choose the Right Variation for You

Here's the honest answer: start with whatever feels pain-free.

If wall squats feel fine but goblet squats bother you, do wall squats. If box squats feel great but regular squats don't...do box squats. The best squat for you is the one you can do consistently without pain.

If your pain is mostly in the front of your knee (around or below the kneecap): Start with the Spanish squat or wall squat. Both reduce stress on the patellar tendon.

If your pain shows up when you go deep: Start with the box squat at a higher height. Control the depth. Build strength in the range that's pain-free, and the depth will come.

If your knee caves inward when you squat: Your outer glute needs work. Start with the sumo squat (the wide stance naturally encourages better knee alignment) and add glute-specific exercises like banded clamshells and glute bridges.

If everything hurts when you squat: That's not a reason to give up. It's a reason to get specific help identifying what's driving the pain. The answer is usually somewhere in the chain, a stiff ankle, a weak hip, a compensation pattern your body picked up and never let go of.

The Bigger Picture

Squatting with knee pain isn't about finding a hack or a workaround. It's about understanding that your body needs to do this movement and meeting it where it is right now.

Your knee is not broken. It's compensating. And when we address the compensation: the weak glute, the stiff ankle, the pattern your body learned when it was trying to protect you, the squat comes back.

Small, consistent effort in the right variation is the path. Not the perfect workout. Not the most advanced exercise. The next right step, done consistently.
