The squat is the lift people most want to do and most often do badly. It's also the one surrounded by the most confident, contradictory advice — knees must never pass your toes, you must hit parallel exactly, there's one correct stance width. Most of that is wrong, or at least far more individual than it's presented. Here's what actually matters, and what's just noise.
Why squat at all?
Because it trains the pattern you use every day — lowering yourself down and standing back up — while loading your quads, glutes, and the muscles that stabilize your spine. It's one of the most efficient lower-body movements there is, and its real-world version happens dozens of times daily, which is why it sits at the centre of functional fitness. Getting it right pays off in and out of the gym.
The setup
Most squat problems are setup problems. Stand with your feet roughly shoulder-width apart, toes turned out slightly — how much depends on your hips, and there's genuine variation between people. Grip the floor with your whole foot, weight spread between heel and the ball of the foot rather than rolling to the inside edge. Brace your core as though you're about to be lightly punched in the stomach. If you're using a bar, position it evenly across your upper back, not on your neck. That braced, stable base is what everything else depends on.
The movement
- Initiate by sitting back and down — hips and knees bending together, not one before the other.
- Keep your knees tracking over your toes, in line with the direction your feet point. The common fault is knees collapsing inward, not knees travelling forward.
- Keep your chest up and your back neutral — you'll lean forward somewhat, which is normal, but the spine shouldn't round or overarch.
- Descend as far as you can with good form. Depth follows your mobility and structure, not a rule.
- Drive back up through your whole foot, standing tall without hyperextending at the top.
Three myths worth killing
| The myth | The reality |
|---|---|
| Knees must never pass your toes | Some forward knee travel is normal and fine for most people, especially with long limbs |
| Everyone must squat to a fixed depth | Depth depends on your hips, ankles, and proportions — go as deep as you control |
| There's one correct stance | Hip anatomy varies; the right stance is the one that lets you move well |
The genuine faults to watch for are different: knees caving inward, the lower back rounding at the bottom, heels lifting off the floor, and the hips shooting up faster than the chest on the way out of the hole. Those are worth fixing. Whether your knee passes your toe by an inch generally isn't.
If your squat feels bad
Heels lifting or a very limited depth is often an ankle or hip mobility issue rather than a strength one, which a mobility routine and a proper warm-up can improve over time. Knees caving usually means the glutes aren't contributing enough — worth addressing directly, sometimes alongside muscle imbalances. And if squatting causes actual pain rather than effort, that's a signal to stop and get it looked at, not to push through; the approach in training around an injury applies.
Variations if the barbell back squat doesn't suit you
There is no obligation to barbell back squat. The goblet squat — holding a weight at your chest — is often the best starting point, because the counterbalance naturally encourages an upright torso and it's easy to bail out of. Front squats shift the load forward, split squats and lunges train each leg independently, and leg presses or hack squats load the pattern with more support. All build the same muscles. Pick the version you can perform well and load progressively, then apply progressive overload — that matters far more than which variation you chose. If you're new to lifting entirely, start with strength training for beginners.
Frequently asked questions
Should my knees go past my toes when squatting? For most people, some forward knee travel is perfectly normal and safe — especially for taller lifters or those with long femurs. The rule against it is outdated. Knees caving inward is the fault actually worth correcting.
How deep should I squat? As deep as you can go while maintaining control and a neutral spine, which varies with your hip structure, ankle mobility, and limb proportions. There's no universal depth everyone must hit; forcing depth you can't control causes more problems than it solves.
Why do my heels come up when I squat? Usually limited ankle mobility, sometimes stance width or technique. Mobility work can improve it over time, and a slightly wider stance or elevating the heels can help you squat well in the meantime.
Is the barbell back squat necessary? No — goblet squats, front squats, split squats, lunges, and machine variations all train the same muscles effectively. Choose the version you can perform well and progressively load; the variation matters far less than execution and consistency.
The bottom line
Squat with a braced core and a stable foot, sit back and down with knees tracking over your toes, keep your spine neutral, and go as deep as you can control. Ignore the rigid rules about knee position, exact depth, and one correct stance — anatomy varies. Fix the real faults (knees caving, back rounding, heels lifting), pick the variation that suits your body, and load it progressively.
Good technique is worth far more inside a structured program than as an isolated tip. The Adaptable Strength & Conditioning System ($19, reg. $29) programs the squat pattern with variations and substitutions, so you're progressing a movement that fits your body rather than forcing one that doesn't.
