Perfect squat form: technique, tips, and common mistakes

Practical Playbook

1. 1

   Set your stance and bar position first

   Feet shoulder-width apart, toes pointed slightly out. The bar sits on your rear delts, not your cervical spine. Elbows pulled back, chest up. I cue lifters to 'break at the hips and knees simultaneously', that single mental image cleans up more squats than any gadget.

2. 2

   What does proper squat depth actually look like?

   Contrary to 'thighs parallel' dogma, the right depth depends on your hip anatomy. Most need thighs at least parallel to the floor. A trick: film yourself from the side. If your pelvis tucks under (butt wink) you're going too deep. Stop where you maintain a neutral spine.

3. 3

   Brace your core and drive through heels

   Take a deep belly breath into your belt (or into your abs if beltless). Hold that brace through the descent. At the bottom, think 'push the floor away' rather than 'stand up.' You should feel pressure midfoot and heel, if you're on your toes, your weight is too far forward. Adjust your torso angle.

4. 4

   Fix the two most common squat errors

   Knees caving in? Push them out against an imaginary band. Torso collapsing forward? Drive your upper back into the bar and keep your elbows down. I've fixed dozens of squats with just those two cues. Use a light load or bodyweight until the pattern sticks.

5. 5

   Add weight without sacrificing technique

   Load increases should come from consistent reps at your current max, not just slapping on 5 lbs. If your last set has form breakdown, that's your true working weight. Periodize: 4 weeks building volume at 70-75%, then a week at 80%+ before deloading. Your safety counts more than the number.

Common Mistakes

• Mistake

  Letting your knees cave inward on the way up from a squat.

  Why

  That valgus collapse puts shear stress on your ACL and meniscus. Over time it grinds down cartilage and can lead to a pop you'll regret.

  Fix

  Drive your knees out toward your pinky toes as you stand. If they still cave, drop the weight by 10-20% and focus on pushing the floor apart with your feet.

• Mistake

  Stopping a few inches above parallel because you 'feel the burn' in your quads.

  Why

  Partial reps shortchange your glutes and hamstrings, leaving serious strength on the table. Your quads take most of the load, but the posterior chain never learns to fire.

  Fix

  Set a box or bench at parallel height and squat until you tap it. No bounce. Crease below the kneecap is the standard. If mobility limits depth, work on ankle dorsiflexion drills.

• Mistake

  Rocking back onto your heels so hard your toes lift off the floor.

  Why

  That shifts the bar path forward of midfoot, turns the squat into a good-morning, and yanks your lower back into a dangerous angle. Your balance should be tripod even throughout.

  Fix

  Keep weight distributed across your whole foot. Think 'grip the floor with your toes' but don't actually curl them. If you're tipping back, try squatting in flat shoes or go barefoot.

• Mistake

  Rounding your lower back at the bottom of the squat (butt wink).

  Why

  That lumbar flexion under load jams the discs posteriorly. Over hundreds of reps it can herniate a disc or cause chronic low-back pain that kills any squat progress.

  Fix

  Brace your core like someone's about to punch you in the gut before you descend. Stop your descent the moment your pelvis tucks under. If it happens consistently, limit depth to where you stay neutral and improve hip mobility with couch stretches.
