How to squat properly — foot position, bar placement, depth cues, bracing, and the technique fixes that let you squat heavy without wrecking your knees or back.

How to squat properly is the difference between building tree-trunk legs and blowing out a lower back. Everyone thinks squat form is about knees over toes. It's not — it's about a braced spine and controlled descent.
I'm Pasha, founder of 1RM.fit. Squat is the second most-logged lift in our database. Here's the complete guide to how to squat with proper form.
The Squat Setup — 6 Key Points
1. Bar Placement
- High bar: Bar on your traps, just below C7 vertebra — more quad dominant
- Low bar: Bar on your rear delts, ~5 cm lower — more posterior chain, heavier possible
- Pick one and stick with it for at least 8 weeks before switching
2. Foot Stance
- Feet shoulder-width apart (slightly wider for low-bar)
- Toes pointed out 15-30°
- Weight distributed across full foot — mid-foot and heel, not toes
3. Bracing
- Big breath IN before you unrack
- Push your stomach out against a belt (or your abs)
- Hold breath through descent, exhale forcefully at top of ascent
4. Knees Track Over Toes
- Push knees OUT in the same direction as your toes
- Knees caving inward = weak glutes, patella pain risk
- Cue: "spread the floor with your feet"
5. Depth
- Hip crease breaks parallel with the top of the knee — that's "depth"
- ATG (ass to grass) is fine if your mobility allows
- Quarter squats do not build strong legs
6. Neutral Spine
- Chest up, back tight, spine neutral (not rounded, not hyperextended)
- Rounding at the bottom ("butt wink") = mobility issue or too-heavy load
- If you can't maintain neutral spine, reduce weight or improve hip mobility
Common Squat Mistakes That Kill Progress
- Not squatting to depth: Half squats build half a leg
- Knees caving in: Fix with band around knees during warmups, cue "push knees out"
- Chest collapsing forward: Weak upper back → drop weight, do more rows and heavy carries
- Butt wink: Fix hip mobility (couch stretch, deep goblet squats)
- No belt on heavy sets: Above 80% 1RM, a belt is a free 5% strength boost
Warm-Up Sets for Squat
Every squat session, ramp to your working weight:
- Empty bar × 10
- 60% × 5
- 75% × 3
- 85% × 2
- 90% × 1 (optional single)
- Then working sets
High Bar vs Low Bar Squat
- High bar: More upright torso, more quad. Better for hypertrophy and Olympic lifters
- Low bar: More horizontal torso, more hips and posterior chain. Higher max weight. Standard for powerlifting
Beginners: start with high bar unless you have a strong reason to go low bar. Easier to learn, less mobility demand.
Should You Squat With a Belt?
Above ~80% of your 1RM: yes. A belt gives you something to brace against, protecting your lower spine and adding 5-10% to your working sets.
Below 80% 1RM: no belt. You need to train your natural bracing capacity.
A proper squat isn't about how much weight is on the bar — it's about how much weight you can move to depth with a braced spine. Ego squats build ego, not legs.
Programming Your Squat
- Beginners: 3x per week, 5×5 → see our 5x5 workout program guide
- Intermediates: 2x per week, 5/3/1 or Madcow
- Advanced: Blocks alternating strength and hypertrophy focus
