Squat: Perfect Technique in 5 Steps
The squat is one of the most studied, coached, and debated movements in fitness. Yet most people still do it wrong. Not because they lack effort, but because the cues they've been given are vague, incomplete, or flat-out misleading. "Keep your chest up" doesn't mean much if you don't know where your feet should be. "Go deep" is useless without understanding what depth actually requires from your body.
Key Takeaways
- Descending until thighs are at least parallel activates glutes and hamstrings fully
- Shoulder-width foot placement suits the majority of body types
- Keeping the bar over mid-foot throughout ensures proper balance
This isn't a beginner's primer on what a squat is. It's a precise, checkpoint-by-checkpoint breakdown of what separates a squat that builds strength and protects your joints from one that slowly grinds them down. Five checkpoints. Clear cues. Common errors and how to fix them.
Step 1: Foot Position and Stance Width
Your foot position sets the foundation for everything that follows. Get it wrong and no amount of cueing further up the chain will save you. There's no single "correct" stance, but there is a correct process for finding yours.
Start with your feet roughly hip-width apart, toes pointed out between 15 and 30 degrees. This angle accommodates the external rotation of the hip joint and allows your knees to track in line with your toes throughout the movement. Narrower stances work for some people, wider for others. The determining factor is your hip socket anatomy, which varies significantly between individuals.
A useful test: get into a deep squat position and assess where you feel restriction. If you feel it in the front of the hip (a pinching sensation), widen your stance slightly and add more toe-out. If your heels rise, your ankle mobility is the limiting factor, not your stance.
- Common error: Feet too parallel, pointing straight forward. This forces internal rotation at the hip and causes the knees to cave inward under load.
- Fix: Rotate your feet out to roughly 20 to 30 degrees and actively think about "screwing" your feet into the floor. This external rotation cue engages the glutes and stabilises the hip throughout the descent.
- Common error: Stance width copied from someone else rather than found individually.
- Fix: Use the deep squat assessment above. Your stance is correct when you can hit depth without heel rise, knee cave, or hip pinching.
Step 2: How Deep Is Deep Enough
Depth is one of the most misunderstood variables in the squat. The blanket instruction to "squat to parallel" ignores the fact that parallel is often insufficient for maximising muscle recruitment, and that full depth is only achievable when mobility allows it.
Research consistently shows that squatting below parallel, specifically to the point where your hip crease drops below your knee, produces greater activation of the quadriceps, glutes, and adductors compared to partial-range squats. A 2019 meta-analysis published in the Journal of Sports Sciences found that full-depth squats generated significantly greater lower-body hypertrophy than half-squats over matched training periods.
The target is to reach a hip crease just below the knee as a minimum, with full depth being hip crease well below the knee for those with adequate mobility. Your lower back should remain neutral throughout. The moment your pelvis tucks under at the bottom (commonly called "butt wink"), you've gone past your current mobility ceiling.
- Common error: Squatting only to parallel or above because "that's all the knee can handle." This misconception persists despite evidence showing that compressive forces on the knee are well within safe ranges during deep squats in healthy individuals.
- Fix: Work on ankle dorsiflexion and hip flexor mobility progressively. Elevating your heels slightly on plates while you build mobility is a legitimate short-term tool, not a cheat.
- Common error: Forcing depth at the cost of a neutral spine, creating aggressive lumbar flexion at the bottom.
- Fix: Squat only as deep as your current mobility allows with a neutral spine. Depth earned through mobility work is permanent. Depth forced through spinal flexion is a liability.
Step 3: Where to Look and Why It Matters
Eye line is rarely treated as a technical variable. It should be. Where you direct your gaze directly influences your cervical spine position, which influences your thoracic spine, which influences your entire torso position under load. It's a chain reaction that starts at your eyes.
The most common advice is to "look forward" or "keep your chin up." Both are oversimplifications. A neutral cervical spine, consistent with the rest of your spinal alignment, means your gaze should be directed slightly downward, roughly 6 to 10 feet in front of you on the floor. This keeps your neck in line with your thoracic spine rather than cranked upward or jammed forward.
Looking excessively upward tends to create hyperextension in the cervical spine and can pull your thoracic spine into extension, which disrupts your brace and shifts your weight forward. Looking down at your feet causes cervical flexion and promotes forward torso lean, especially under heavier loads.
- Common error: Staring at the ceiling or a fixed point directly ahead at eye level. This is a compensatory habit, often adopted to "stay tall," but it creates unnecessary tension and misalignment in the upper spine.
- Fix: Find a spot on the floor roughly 2 to 3 metres in front of you. Keep your focus there throughout the entire rep. Practice this without load first until it becomes automatic.
- Common error: Eye line shifting during the rep, looking down on the descent and forward on the ascent. This introduces inconsistency in spinal position at the most demanding moments of the lift.
- Fix: Lock your gaze before you initiate the movement. It doesn't change until the rep is complete.
Step 4: Breathing and Bracing
Breathing in the squat is not about comfort. It's about intra-abdominal pressure, the internal force that stabilises your spine under load. Done correctly, it's one of the most powerful protective mechanisms you have. Done incorrectly, it leaves your spine vulnerable during the exact moment it needs to be most stable.
The technique is called the Valsalva maneuver. Before you descend, take a deep breath into your belly (not your chest), brace your core as if you're about to take a punch, and hold that breath through the descent and the most demanding portion of the ascent. Release it at the top of the rep. This breath-hold creates intra-abdominal pressure that acts like an internal brace around your spine.
Studies have demonstrated that intra-abdominal pressure during a properly executed Valsalva can reduce compressive spinal loading by a measurable margin. For heavy lifting, this isn't optional technique. It's basic load management.
- Common error: Breathing continuously throughout the rep, exhaling on the way up. This collapses intra-abdominal pressure at the point of highest spinal load, which is typically just below parallel on the ascent.
- Fix: Breathe and brace before the rep begins. Hold through the sticking point. Exhale fully only after you've locked out at the top.
- Common error: Bracing the chest and upper abs only, rather than expanding 360 degrees around the trunk, including the lower back and sides.
- Fix: Think about pushing your belt out in all directions when you brace. If you wear a belt, try to push against it from the inside. This cue reliably activates the full circumferential brace rather than just the front of the core.
Step 5: Tempo and Control
How fast you squat determines how much you're actually training versus how much you're just surviving the load. Tempo is the variable most commonly ignored in recreational training and most deliberately programmed in elite settings. That gap tells you something.
A controlled descent, typically 2 to 3 seconds, increases time under tension for the quadriceps and glutes and forces you to own every position on the way down. A pause at the bottom, even 1 second, eliminates the elastic rebound that masks weakness and forces your muscles to generate force from a dead stop. A strong, powerful ascent trains the rate of force development you'll need for athletic performance and heavier loads over time.
A common evidence-based prescription for building strength and technique simultaneously is a 3-1-X tempo: 3 seconds down, 1 second pause at the bottom, as fast as possible on the way up. This isn't mandatory, but it's a reliable framework that exposes weaknesses quickly and removes the momentum that covers for poor mechanics.
- Common error: Dropping fast through the descent and using the bounce at the bottom to drive the ascent. This loads the passive structures of the knee (ligaments, tendons, menisci) rather than the muscles, and it hides the point in the range of motion where your strength actually breaks down.
- Fix: Reduce your load and practice controlled descents first. The weight you can squat with full control is your actual working weight, regardless of what you can bounce up with.
- Common error: Slowing the ascent, especially through the sticking point just above parallel. A slow ascent under heavy load is a sign the weight is too heavy, not a technique virtue.
- Fix: Treat every ascent as maximal effort. Push the floor away as hard as possible. If the bar still slows dramatically, reduce the load until you can express proper intent on every rep.
Putting the 5 Checkpoints Together
Here's the honest truth: most technique breakdowns fail because they treat each variable in isolation. In reality, your foot position influences your achievable depth. Your depth influences your eye line. Your eye line influences your brace. Your brace is what makes controlled tempo possible. These five checkpoints aren't independent. They're sequential and interdependent.
The most effective approach is to audit them in order. Establish your foot position first. Build your depth within your current mobility. Lock your gaze. Load your brace before every rep without exception. Then move with intent, down under control, pause if you need to own the bottom, and drive up hard.
You don't need to fix everything at once. Pick the checkpoint that most clearly applies to your current squat, work it into your next session, and build from there. Technique compounds. A small correction applied consistently across hundreds of reps becomes your new default. That's where real progress is built.
If you want to go further, pairing this framework with regular mobility work for ankle dorsiflexion and hip flexor range of motion will accelerate every one of these checkpoints. The squat doesn't ask for perfection. It asks for precision, applied consistently over time.
Frequently Asked Questions
How deep should you squat?
At minimum, thighs parallel to the floor. Deeper squats activate more glutes and hamstrings, as long as you maintain proper back posture.
Are squats bad for your knees?
No, with proper technique. Research shows squats strengthen knee structures. Problems come from loads too heavy for your skill level or poor mobility.
Barbell or goblet squat for beginners?
Goblet squats are ideal for learning since front-loading helps keep the torso upright. Switch to barbell once technique is solid and you need heavier loads.
