In short — Most squat problems come from five fixable setup errors, not from 'bad knees' or the wrong body. Stance, bracing, depth and bar path — in the order to check them.

The squat rewards people who set up well. Almost every ugly squat you see in a gym traces back to the same short list of setup issues — and almost none of them require new anatomy to fix. Work through this checklist in order.

1. Stance: yours, not a diagram’s

Start with feet roughly shoulder-width, toes turned out 15–30 degrees — then experiment. Hip sockets vary enormously between people; some squat best narrow and straight, others wide and turned out. The test is simple: the stance that lets you reach depth with a balanced foot and no pinching in the groin is your stance. Your whole foot stays planted — heel included — like a tripod screwed into the floor.

2. The brace comes before the descent

Take a full breath into your belly and sides, then tighten your trunk as if about to be punched. This intra-abdominal pressure is your spine’s support system under load; the exhale-as-you-descend pattern from light aerobics classes does not scale to a loaded barbell. Hold the brace until you are most of the way up, reset at the top, repeat. A belt can help you brace harder — it is a tool for pressure, not a brace substitute or a safety guarantee.

3. Depth: as deep as your control allows

The useful standard is the crease of the hip dropping just below the top of the knee — deeper if your mobility and control allow it, shallower while you earn the range. Half-squats are not evil (they overload the top range), but most people half-squat by accident, with loads their full squat could never handle, and call it strength. Deep squats are not knee poison either: in healthy knees, research reviews find loaded deep flexion well tolerated when progressed sensibly. Pain, not depth, is the stop signal.

4. Knees track toes — and the ‘butt wink’ panic

Knees should travel in line with the toes, out rather than caving in; a cue of ‘spread the floor’ fixes most caving. As for posterior pelvic tilt at the bottom (‘butt wink’): a small amount is common and usually harmless; it becomes worth addressing when it is large, sudden, or paired with back pain — often a stance or ankle-mobility issue rather than a character flaw.

5. Bar path and the way up

The bar should travel in a near-vertical line over the middle of your foot. Rising, drive your back up into the bar and push the floor away — hips and shoulders ascending together. If your hips shoot up first (the ‘good-morning squat’), the load is usually too heavy or your quads need direct work. Film one set from the side every week; the camera catches what fatigue hides.

Bottom line: stance that fits your hips, a real brace, honest depth, knees tracking toes, vertical bar path. Fix them in that order and most squat problems fix themselves.

Frequently asked questions

Should my knees stay behind my toes?

No — that cue is outdated. Knees travelling past the toes is normal and necessary for most people at depth; forcing them back shifts load to the hips and lower back. Knees should track in line with the toes, not cave inward.

Are deep squats bad for my knees?

Reviews of the evidence find deep squats are well tolerated by healthy knees when load is progressed gradually. If you have an existing knee condition, depth and load should be set with your clinician or physio — pain is the guide, not a universal depth ban.

I can't hit depth without my heels lifting. What gives?

Usually ankle mobility or stance. Try a slightly wider stance with more toe-out, and a small heel lift (weightlifting shoes or plates under heels) while you work on ankle range — the lift is a legitimate tool, not cheating.
