Proper squat technique starts in the first 2 inches

The mistake happens before you even descend

Most people think proper squat technique is about depth — how low they go. It's not. It's where they start.

Foot position, bar placement, and bracing: if any of those three are off, every rep after that is damage control. You're not squatting badly because you're weak. You're squatting badly because the setup is wrong.

Fix the first 2 inches of the movement — the stance, the grip on the bar, the breath — and the rest mostly fixes itself.

You're not squatting badly because you're weak. You're squatting badly because the setup is wrong.

Foot width: shoulder-width is a starting point, not a rule

Shoulder-width stance is the default cue — and it's fine for most people, most of the time. But your hip socket doesn't care about your shoulders.

Hip anatomy varies a lot between individuals. Some people have hip sockets that sit more forward-facing; others are more angled outward. If your hips are naturally rotated outward, a narrow stance will fight your anatomy on every single rep. You'll feel it as tightness in the groin at the bottom, or your heels coming up.

The fix: stand with feet slightly wider than shoulder-width, toes pointed out 15–30 degrees. Sit into a deep squat and notice where you feel the most range of motion. That's your stance. It might look a little different from the person squatting next to you — that's fine.

One universal rule: your knees must track in the same direction as your toes. If your toes are pointed at 25 degrees and your knees collapse inward, that's the problem — not the angle itself. Knee cave (knees dropping inward during the squat) puts sideways stress on the knee joint it was never designed to handle.

Your knees must track in the same direction as your toes — every single rep.

Bar position: low bar vs high bar changes everything about the movement

There are two main bar positions for the barbell squat. Neither is wrong. But mixing them up is.

High bar: bar rests on top of the traps — the meaty shelf at the base of your neck. This keeps your torso more upright and puts more work through the quads (the muscles at the front of your thigh).

Low bar: bar sits 2–3 inches lower, across the rear deltoids — the back of the shoulder muscles. This shifts your torso forward slightly and loads the posterior chain more. The posterior chain means the muscles down the back of your body: glutes, hamstrings, and lower back.

Beginners usually do better starting with high bar. It's more forgiving on shoulder and wrist flexibility, and the upright torso position is easier to control.

The mistake: accidentally using a high-bar body position (upright torso) with a low-bar placement. The bar slides, your upper back has nothing to grip, and the load shifts onto your spine rather than your muscles. Before you unrack, actively squeeze your shoulder blades together to create a solid shelf for the bar to sit on.

Bracing your core isn't sucking your stomach in

Before every rep, you need intra-abdominal pressure — which is just a fancy way of saying you need to pressurize your trunk like a can of soda, so your spine has rigid support on all sides.

Here's how to do it:

1. Take a big breath into your belly (not your chest). Your stomach should push outward, not your ribs up.
2. Hold that breath and brace your abs as if someone is about to punch you in the stomach.
3. Only then do you descend.

Sucking your stomach in does the opposite. It reduces core pressure and leaves your lower back with less support right when it needs it most — at the bottom of the squat where the load on your spine is greatest.

That breath held during the descent is called the Valsalva maneuver. It sounds technical but it means: breathe in, hold it, brace hard, squat, stand, breathe out at the top. Repeat. For beginners lifting moderate weights, this is the single most protective thing you can do for your lower back.

Breathe in, hold, brace hard, squat, stand, breathe out. That one cue protects your lower back more than any other.

Depth: below parallel is the goal, but earning it matters

Below parallel means your hip crease — the fold at the front of your hip — drops below the top of your knee. That's the standard for a full squat.

But here's the thing: depth is a byproduct of mobility, not effort. If your ankles can't flex forward enough (dorsiflexion — bending your foot toward your shin), your heels will lift off the floor long before you hit depth. If your hips are tight, you'll compensate by letting your lower back round at the bottom — called a butt wink — and that shifts load onto your lumbar discs instead of your muscles.

The right progression:
- Start with a box squat or goblet squat (holding a light dumbbell or kettlebell at chest height). Both naturally reinforce an upright torso. See more on why the goblet squat benefits is so effective as a teaching tool.
- Add a heel elevation (a small plate under each heel) if ankle mobility is limiting you. This is not cheating — it's a drill, and you can phase it out as your ankles open up.
- Only add weight when you can hit depth consistently without your lower back rounding.

Squatting high with a heavy weight is not progress. It's just lifting less muscle. The quads and glutes aren't fully loaded until you hit parallel — above that, you're primarily loading your lower back.

The drive out of the hole: push the floor away, not forward

The bottom of the squat — the 'hole' — is where most form breaks down. Your torso caves forward, your knees shoot inward, and the rep turns into a good morning (a different exercise entirely, where you hinge forward at the hips and load your lower back instead of your legs).

Two cues fix this almost immediately:

1. Push the floor away from you. Don't think about standing up. Think about driving your feet straight down through the floor. This activates your glutes and quads simultaneously and keeps your torso upright.

2. Spread the floor with your feet. Imagine you're trying to tear a piece of paper in half with your feet — pushing them slightly outward into the floor without actually moving them. This external-rotation cue keeps your knees tracking over your toes and switches on your glutes from the start of the drive.

If your chest dives forward on the way up, it usually means one of two things: your upper back isn't tight enough (go back to the bar-placement section), or the weight is too heavy. Drop the weight, nail the pattern, then add load. Form breakdown under heavy load is not training — it's practicing the wrong movement.

The 5-point checklist before every working set

Run through this before you unrack the bar. It takes about 10 seconds.

1. Stance set. Feet shoulder-to-hip-width, toes out 15–30°.
2. Bar locked in. Shoulder blades squeezed together, bar sitting on a solid shelf.
3. Big breath in. Into the belly, not the chest.
4. Brace hard. Abs tight like you're about to take a hit.
5. Eyes forward or slightly up. Not at the ceiling — that hyperextends your neck. Not at the floor — that encourages your chest to follow.

Once you're under load, the only cues you need mid-rep are: knees out, chest up, push the floor. Three things. Any more and you're thinking too hard to lift well.
