You’ve probably heard it a thousand times. "Keep your knees behind your toes." Honestly? That’s mostly nonsense. If you try to keep your knees perfectly vertical while sitting back into a deep squat, you’ll likely just fall over backward or end up with a lower back that feels like it’s being crushed by a hydraulic press. Squatting is arguably the most fundamental movement humans do, yet we’ve managed to overcomplicate it to the point of paralysis.
Think about it.
Little kids squat perfectly. They sit deep, heels flat, chest up, and stay there for twenty minutes playing with LEGOs. They don't have "tight hip flexors" or "poor ankle mobility" yet. They just move. But then we sit in office chairs for twenty years and suddenly, learning how to do squat mechanics properly feels like trying to learn quantum physics while balancing on a tightrope.
It’s not just about the quads. It’s a full-body symphony. If one instrument—say, your big toe or your upper back—is out of tune, the whole thing sounds like garbage.
The Anatomy of a Movement Most People Get Wrong
When you start looking at how to do squat variations, you have to look at your skeleton. Not everyone is built the same. Dr. Stuart McGill, a world-renowned expert in spine biomechanics, often talks about how hip socket depth varies wildly between different ethnicities and individuals. If you have deep hip sockets (common in those of Scottish descent, for example), you might never be able to do a "butt-to-grass" squat without your pelvis tucking under—a move called the "butt wink."
If you have shallow sockets (more common in Eastern European populations), you might be a natural-born squatter.
The point? Stop trying to look like a fitness influencer on Instagram. Your squat will look like your squat.

First, let's talk about the feet. Your feet are your foundation. Most people think they should just stand there, but you actually need to "screw" your feet into the floor. Imagine you’re standing on a giant piece of paper and you’re trying to tear it in half by spreading your feet apart without actually moving them. This creates external rotation torque in the hips. It stabilizes the pelvis. It keeps your knees from caving in (valgus collapse), which is the fastest way to an ACL tear or chronic meniscus issues.
Physics Doesn't Care About Your Workout Goals
Gravity pulls straight down. That’s a fact. When you’re learning how to do squat reps with weight, the bar path should ideally stay over the middle of your foot. If the bar drifts forward toward your toes, you’re putting massive shear stress on your patellar tendon. If it drifts too far back, you’re going to strain your erector spinae.
Why Your Heels Keep Lifting
If your heels pop up when you go low, you don’t have a "squat" problem. You have an ankle problem. Specifically, poor dorsiflexion. If your shin can’t lean forward, your body has to find that range of motion somewhere else. Usually, it finds it by lifting the heel or rounding the back.
Try this: stand facing a wall with your toes about four inches away. Try to touch your knee to the wall without your heel coming up. Can’t do it? You need to work on your soleus and gastrocnemius flexibility. Or, just cheat a little. Put some 5-pound plates under your heels. It’s a band-aid, sure, but it allows you to hit depth while you work on your mobility. Professional weightlifters wear shoes with an elevated heel for this exact reason. It’s not "cheating"; it's mechanical optimization.
The "Core" Is More Than Just Six-Pack Abs
Let’s talk about the "Valsalva Maneuver." It sounds fancy, but it’s basically just how you breathe so you don’t snap yourself in half. You don't just "suck your belly button to your spine." That's actually terrible advice for heavy lifting.
Instead, think about your torso as a soda can. An empty soda can is easy to crush. A full, unopened soda can? You could probably stand on it. You want to take a huge breath into your belly—not your chest—and hold it. Push your abs out against your belt or your waistband. This creates intra-abdominal pressure. It turns your soft midsection into a rigid pillar that protects your spine.
Bracing vs. Hollowing
There was this big trend in the 90s about "hollowing" the gut. Forget it. When you’re figuring out how to do squat sets with any kind of intensity, you need "bracing."
Imagine someone is about to punch you in the stomach. You wouldn't suck your stomach in, right? You’d stiffen up. You’d get wide. That’s the feeling you want before you start your descent.
Different Flavors of Squats
Not all squats are created equal. Depending on your goals, you might want to switch things up.
- The Goblet Squat: This is the gold standard for beginners. Holding a kettlebell or dumbbell at your chest acts as a counterbalance. It actually forces you to stay upright. If you can't do a goblet squat, you shouldn't be under a barbell.
- The Back Squat (High Bar): The bar sits on your traps. This is the "classic" look. It’s more quad-dominant and requires more ankle mobility.
- The Back Squat (Low Bar): The bar sits lower on your rear deltoids. Powerlifters love this. It allows you to lean forward more and use your massive posterior chain (glutes and hamstrings) to move huge weight.
- The Front Squat: The bar sits on your collarbones/shoulders. It’s brutal. If your core is weak, you will fail this lift immediately. It’s the ultimate "no-BS" exercise.
Common Mistakes That Are Secretly Killing Your Gains
Most people focus on the way down. The "eccentric" phase. But the transition—the "hole"—is where things go sideways.
Don't just dive-bomb. If you drop too fast, you lose tension. When you lose tension, your joints take the load instead of your muscles. You want a controlled descent. Think about a three-second count on the way down. Feel the tension building in your hamstrings like a loaded spring. Then, explode up.
And for the love of everything holy, stop looking at the ceiling.
People used to say "look up to go up." No. That puts your cervical spine into hyperextension. It’s a great way to get a pinched nerve. Keep your neck "packed." Look at a spot on the floor about six to ten feet in front of you. This keeps your spine in a neutral line from your tailbone to the base of your skull.
The Truth About Knee Health
"Squats are bad for your knees" is a myth that needs to die. Research, including studies cited by the National Strength and Conditioning Association (NSCA), shows that deep squats can actually increase knee stability because the surrounding musculature becomes so much stronger. The pressure on the ACL actually decreases the deeper you go into a squat, while the pressure on the PCL increases—but remains well within the limits of what a healthy ligament can handle.
The danger isn't the depth. The danger is the ego.
If you add 50 pounds to the bar but cut your range of motion in half, you aren't getting stronger. You're just getting better at being loud in the gym. True strength is found in the full range of motion.

Actionable Steps to Master Your Squat
Stop overthinking. Start doing. But do it with a plan.
First, check your stance. Start with your feet shoulder-width apart and toes pointed slightly out—maybe 15 to 30 degrees. This opens up the hip capsule. If you feel a "pinch" in the front of your hip, your stance is likely too narrow for your bone structure.
Second, master the hinge. A squat isn't just "bending your knees." It’s a simultaneous hinge of the hips and bending of the knees. If you find yourself shifting forward onto your toes immediately, try "box squats." Sit back onto a bench or a box. It teaches you to find your glutes.
Third, film yourself. We all think we look like Olympians until we see the video. Look for the "butt wink" where the lower back rounds at the bottom. If you see it, stop your depth just before it happens. Over time, as your mobility improves, you'll get deeper.
Fourth, check your bracing. Can you hold a conversation while your core is tight? You should be able to. It's about tension, not just holding your breath until you turn purple.
Finally, frequency matters more than intensity when you’re learning. Squat three times a week, but keep the weight light. You’re "greasing the groove." You’re teaching your nervous system that this movement is safe. Once the pattern is burned into your brain, then—and only then—should you start chasing personal records.

Get your shoes off. Try a few bodyweight reps right now. Feel where the weight is in your feet. If it's on your big toe or your heel, adjust until it's centered. That's the start of a better squat.
