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.
