How to Do a Proper Squat: Form, Mistakes and Fixes

You have squatted thousands of times without thinking about it: every time you sit down, stand up, or pick something off the floor. So why does the gym version feel so awkward? The truth is that a "bad" squat is rarely about weakness or bad genetics. It is almost always a handful of fixable habits, and once you see them, you cannot unsee them. Here is exactly how to do a proper squat, the mistakes that trip up nearly everyone, and the fixes that make it click.

Why the Squat Earns Its Reputation

The squat is often called the king of exercises, and for once the gym hype is justified. It trains the largest muscles in your body at the same time: the quadriceps on the front of your thighs, the glutes, the hamstrings, and the muscles deep in your hips. Your core and lower back work hard just to keep you upright. Few movements give you that much return for one exercise, which is why physical-activity guidance from bodies like the CDC and WHO leans heavily on strengthening movements that recruit major muscle groups at least twice a week.

The payoff goes well beyond looking strong. A proper squat builds the exact pattern you use to get out of a chair, climb stairs, and lift a child or a grocery bag without tweaking your back. Researchers and clinicians treat this hip-hinge-and-bend pattern as a marker of functional fitness, especially as we age. Train it well now and you are quite literally practicing independence for later in life.

Best of all, the bodyweight squat costs nothing and needs no equipment. You can master the movement in your living room before a single weight enters the picture. That is the sequence I would push every smart beginner toward: own the pattern first, add load second.

The Step-by-Step Proper Squat

Start with your feet roughly shoulder-width apart, toes pointed out slightly, somewhere between 5 and 30 degrees depending on what feels natural for your hips. Stand tall, brace your midsection as if you were about to be lightly poked in the stomach, and let your arms hang or extend forward for balance. This bracing is not optional flourish; it is what keeps your spine stable as you descend.

Now initiate the movement by pushing your hips back and down at the same time, as if reaching your backside toward a chair behind you. Let your knees bend and travel forward over your feet, and crucially, let them track in the same direction as your toes. Keep your chest proud and your gaze forward or slightly down. Descend under control, taking about two seconds on the way down rather than dropping like a stone.

Aim to lower until your thighs are at least parallel to the floor, meaning your hip crease drops to roughly knee height. Going below parallel is fine and often desirable if you can do it without your form falling apart. At the bottom, drive through your whole foot, especially your heels and midfoot, and stand back up by pushing the floor away and squeezing your glutes at the top. One clean rep beats five sloppy ones, so prioritize quality. A set of 8 to 12 controlled bodyweight squats is a perfectly respectable place to begin.

Mistake 1: Knees Caving Inward

The single most common squat error is letting the knees collapse toward each other on the way up, a fault coaches call valgus collapse. You will often see it on the final hard reps of a set, when fatigue sets in and the body looks for the path of least resistance. It usually points to underactive glutes, particularly the muscles on the outside of the hip that are supposed to hold your knees in line.

The fix is part cue and part strength. The cue: actively think push the knees out, spreading the floor with your feet so your knees track over your second and third toes. Many people find that simply being told to do this corrects most of the wobble immediately. For a more durable fix, loop a light resistance band just above your knees and do a set of bodyweight squats; the band gives you something to push against and teaches the pattern fast.

A word of nuance: a small amount of inward knee movement under heavy load is not automatically dangerous, and the old fear that knees moving past the toes will wreck your joints is largely a myth for healthy people. The goal is control, not paralysis. If you have a history of knee injury or you feel pain rather than effort, that is your signal to scale back and check in with a physiotherapist or doctor.

Mistake 2: Heels Lifting and Falling Forward

If your heels pop off the floor or your torso pitches forward until you are practically doing a good-morning, your weight is drifting too far toward your toes. This makes the squat feel front-heavy and grinds the load onto your lower back and knees instead of spreading it across the hips and thighs. It is one of the fastest ways to make squats feel unpleasant and unstable.

The most common culprits are limited ankle mobility and trying to keep the torso too upright, too soon. Test it: do a squat with your heels resting on a pair of thin weight plates or a low wedge, raising them maybe half an inch. If your depth and balance instantly improve, tight ankles are a major factor. In that case, weighted-shoes or a small heel lift are a legitimate, widely used tool, not cheating.

Alongside the quick fix, build mobility over weeks with simple ankle drills. A knee-to-wall stretch, where you place your foot a few inches from a wall and drive your knee toward it without lifting the heel, is the standard. Pair that with the cue keep your whole foot planted and think of the floor as a tripod under your big toe, little toe, and heel. Distribute pressure evenly and the forward pitch tends to resolve.

Mistake 3 and 4: Going Too Shallow and Rounding the Back

Two more faults travel together more often than you would think. The first is the quarter squat, dipping a few inches and calling it a rep. Partial squats have their place for very heavy strength work, but for most people learning the movement, cutting depth short shortchanges the glutes and hamstrings and teaches a habit that is hard to break. Hitting at least parallel is the standard you should chase before adding meaningful weight.

The opposite problem appears at the bottom of a deep squat: the lower back rounds and the pelvis tucks under, the so-called butt wink. A tiny, smooth tuck at the very bottom is normal and not a crisis. The concern is a pronounced round under load, which shifts stress onto spinal structures that are not built to take it repeatedly. Bracing your core hard and stopping just above the depth where the rounding begins is the simple, sensible answer.

Fix both by scaling the movement rather than forcing it. A box squat, where you sit back to lightly touch a bench or box set at parallel, teaches honest depth and gives you a target. A goblet squat, holding a single dumbbell or kettlebell against your chest, counterbalances your body so you can sit deeper with a tall spine. Both are beginner-friendly drills that often clean up depth and back position within a week or two of practice.

Mistake 5: Loading Up Before You Are Ready

The final mistake is not about your body position at all; it is about your ego. Plenty of beginners pile on weight before they have grooved the pattern, then wonder why every other fault on this list shows up at once. Heavy load magnifies whatever your bodyweight squat already does, good or bad. If your knees cave and your heels lift with no weight, a loaded bar will only make it worse and more uncomfortable.

Progress instead with a clear ladder. Earn 2 to 3 sets of 10 to 15 clean bodyweight squats, then move to goblet squats, then to a barbell or other external load only when your form holds. When you do add weight, increase it gradually; a common, sustainable approach is to add a small amount only once you can complete all your prescribed reps with good technique. Patience here is not the slow path, it is the fast one, because you avoid the setbacks that come from grinding ugly reps.

Finally, listen to the difference between effort and pain. Burning muscles and breathlessness are the workout doing its job. Sharp, pinching, or joint-specific pain is not, and pushing through it is the opposite of toughness. If something hurts, stop, reduce the load or depth, and if it persists, talk to a qualified health professional. Squatting should leave you stronger, not sidelined.
