Learn how to squat with proper form, avoid common mistakes, and adjust the movement to your body so you can build strength safely and confidently.
A safe squat starts with a neutral spine, full-foot balance, and controlled depth within your current mobility.
Hip and knee alignment over the mid-foot protects your joints and boosts strength and power.
Small adjustments to stance, bar or weight position, and mobility work can tailor squats to your body and goals.
This guide breaks the squat down into clear phases: setup, descent, depth, ascent, and finishing. For each phase, you’ll learn exact joint positions, muscle engagement, and cues used by strength coaches and physical therapists. We also cover variations, common errors, and safety checks so you can progress from bodyweight to loaded squats confidently, regardless of experience level.
Squats are one of the most effective exercises for strength, muscle, and longevity, but poor form can stress knees, hips, and your lower back. Understanding proper technique protects your joints, improves performance, and makes your progress more sustainable over years, not just weeks.
Before you move, you need a solid foundation. Stance: - Stand with feet about hip- to shoulder-width apart. - Toes slightly turned out (around 5–30 degrees) depending on your hip structure; choose the angle where your knees can track naturally over your toes. Posture: - Stand tall with ribcage stacked over pelvis. - Imagine a straight line from ear to shoulder to hip to ankle. - Gaze straight ahead or slightly down (not up at the ceiling). Bracing: - Take a breath into your belly and sides, not just your chest. - Gently tighten your core as if preparing for a light punch. - Keep your spine neutral—no exaggerated arch, no rounding.

How you start the squat determines where the stress goes. Movement pattern: - Start by pushing your hips back slightly, then bend your knees—think "sit between your hips," not just "knees forward." - Keep your weight over the middle of your feet, not just your heels and not your toes. - Allow your knees to travel forward over your toes as needed; this is normal and often necessary. Upper body: - Maintain a proud chest without flaring your ribcage up. - Keep your spine in a neutral position—no collapsing or over-arching. Control: - Descend with a smooth, controlled tempo (about 2–3 seconds). - Stop if you feel sharp pain in knees, hips, or back; adjust stance or depth.

Proper squatting is less about forcing a universal stance and more about maintaining consistent principles—neutral spine, full-foot pressure, and knee–hip alignment—within your personal mobility and structure.
Most chronic squat problems come from either progressing load faster than your technique can handle or ignoring ankle and hip mobility; addressing these two factors often resolves pain and plateaus.
Starting with simpler variations like goblet and box squats builds the coordination, stability, and confidence needed to load back and front squats safely over time.
Breathing and bracing are performance multipliers; once stance and movement are dialed in, improving core stability often yields the largest jump in how strong and secure squats feel.
Frequently Asked Questions
In a well-executed squat, you’ll primarily feel your quads, glutes, and core working. Your feet should feel solid but not painful, and your lower back may feel engaged but not strained or pinched. If you feel sharp pain in your knees or back, reduce load, adjust stance, and revisit technique or consult a professional.
No. For many people, especially those with longer femurs or good ankle mobility, the knees naturally move slightly past the toes. This is normal and safe when combined with good control and full-foot pressure. What matters more is that your knees track in line with your toes and don’t collapse inward.
Your depth is safe when you can maintain a neutral spine, balanced feet, and aligned knees without pain. For many, that’s at or just below parallel, but if you lose tension, your lower back rounds, or joints feel pinchy, shorten the range slightly and gradually build mobility and control before going deeper.
Most beginners benefit from mastering bodyweight and goblet squats before moving to barbells. These variations teach balance, bracing, and depth with lower risk. Once you can perform 3–4 sets of 8–12 goblet squats with stable, consistent form, transitioning to back or front squats is usually smoother and safer.
Focus on a strong core brace, maintaining a neutral spine, and keeping hips and chest rising together out of the bottom. Reduce load until you can perform all reps without discomfort, avoid excessive forward lean, and consider front or goblet squats if back squats irritate your lower back. Persistent pain warrants an assessment with a qualified clinician.
Squatting with proper form is about applying a few core principles—neutral spine, solid bracing, balanced feet, and aligned hips and knees—to the variation and depth that fit your body. Start with bodyweight or goblet squats, refine your technique, then gradually add load and intensity so you can build strength, muscle, and confidence safely over the long term.

There is no one “perfect” depth for everyone. Proper depth is the deepest position you can reach while keeping tension, balance, and a neutral(ish) spine. General guideline: - Aim for thighs at least parallel to the floor if mobility and comfort allow. - Some lifters can safely go deeper ("ass to grass"), others may be limited by hip structure, ankle mobility, or injury history. Good depth signs: - Feet stay flat and balanced. - Knees track in line with your toes (not caving in). - Spine stays neutral; no visible butt wink (pelvis tucking under) that causes lower-back rounding. If depth is limited: - Reduce load and practice goblet squats. - Elevate heels slightly (small plates or squat wedges). - Work on ankle and hip mobility between sets.

The way you come out of the bottom determines your strength gains and joint stress. Direction: - Think "push the floor away" rather than "stand up with your back." - Drive through the full foot, with a slight emphasis on mid-foot and heel. Hip–knee coordination: - Let hips and chest rise together; avoid hips shooting up first, which turns the movement into a good morning. - Keep knees tracking over toes—don’t let them collapse inward. Core and breathing: - Maintain your brace as you begin to stand. - Exhale gradually as you pass the hardest part of the lift, or use a brief, controlled exhale through pursed lips while staying braced. Finish: - Stand tall at the top without leaning back or overextending your lower back.

Correcting technique errors can immediately make squats feel better and safer. Heels lifting: - Likely ankle mobility or stance issue. - Fix: slightly widen stance, turn toes out a bit more, elevate heels on small plates, and add calf/ankle mobility work. Knees cave inward (valgus): - Often from weak hips, poor foot pressure, or going too heavy. - Fix: consciously push knees out in line with toes, reduce weight, and strengthen glutes with exercises like lateral band walks. Leaning too far forward: - Can be due to bar position, tight hips/ankles, or weak core. - Fix: use goblet squats to practice upright posture, improve ankle mobility, and brace harder. Lower-back rounding (butt wink): - Often from limited hip or ankle mobility or forcing too much depth. - Fix: reduce depth to where spine stays neutral, work on mobility, and gradually increase range.

Before loading a barbell, it’s smart to master simpler versions. Bodyweight squats: - Perform in front of a box or bench set just below parallel. - Lightly tap the box at the bottom without fully sitting. - Use a counterbalance (arms straight in front) if balance is challenging. Goblet squats: - Hold a dumbbell or kettlebell close to your chest. - The front load encourages a more upright torso and can make it easier to sit into the squat. - Focus on controlled tempo and consistent depth. Programming: - 2–4 sets of 8–12 reps, 2–3 times per week. - Stop 1–3 reps before fatigue to keep form crisp.
Great for
Different bar positions change muscle emphasis and joint angles. Back squat: - Bar rests across upper traps (high-bar) or slightly lower on rear delts (low-bar). - Allows heavier loads for many lifters. - More hip and posterior chain (glutes, hamstrings) emphasis, especially with a slight forward lean. - Better for maximal strength and powerlifting. Front squat: - Bar rests across the front of shoulders, with elbows high. - Torso stays more upright, increasing quad and core demand. - Generally easier on the lower back but more mobility-demanding in wrists and upper back. - Great for athletes, general strength, and carrying over to Olympic lifts. Choose based on comfort, goals, and available mobility; many lifters benefit from including both over time.

Proper breathing transforms your squat from shaky to solid. Intra-abdominal pressure: - Inhale through your nose, expanding your belly, sides, and lower back against your belt line (real or imaginary). - Gently contract your abs and obliques to create a "360-degree" brace. During bodyweight/light squats: - Inhale on the way down, exhale steadily on the way up. During heavier squats: - Many lifters inhale and brace at the top, hold through the descent and the hardest part of the ascent, then exhale near the top. - If you have blood pressure or heart concerns, use shorter breath holds and consult a professional. A strong brace protects your spine and lets your legs produce more force safely.
Great for
If squats feel stiff or unbalanced, targeted mobility can help. Ankles: - Limited dorsiflexion (knee traveling over toes) often leads to heels lifting or excessive forward lean. - Try: knee-to-wall ankle rocks, calf stretches, and controlled heel raises. Hips: - Tight hips can cause shallow depth or butt wink. - Try: 90/90 hip rotations, deep squat holds while holding onto a support, and hip flexor stretches. Thoracic spine (upper back): - A stiff upper back can force the lower back to compensate. - Try: thoracic extensions over a foam roller, open-book rotations. Use 5–10 minutes before squatting for light mobility, then let the first 1–2 warm-up sets be your main "mobility" work.
Great for
Good form matters most when you’re fatigued or progressing load. Frequency: - 1–3 squat sessions per week is plenty for most people. Sets and reps: - Technique and general strength: 3–4 sets of 5–8 reps. - Hypertrophy (muscle gain): 3–5 sets of 6–12 reps. - Power/strength-focused: 3–6 sets of 3–5 heavier reps. Progression: - Increase load gradually (for example, 2.5–5 kg per week) if you can complete all reps with form integrity. - Alternatively, add 1–2 reps per set or an extra set before increasing weight. Auto-regulation: - Stop each set with 1–3 reps still "in the tank" (you could do more but choose not to) to preserve technique and recovery.
