How to Squat: Master the King of All Exercises

Why the Squat Earns Its Reputation

The barbell back squat is called the king of exercises for good reason. No other single movement trains as much muscle mass through as large a range of motion. Quadriceps, glutes, hamstrings, adductors, core stabilizers, spinal erectors, and even your upper back all work together to move the bar through a full squat.

The squat builds functional strength that transfers to athletics, daily life, and every other exercise in the gym. It develops mobility, stability, and coordination. And it provides a training stimulus so potent that it drives adaptation across your entire body.

But the squat is also one of the most technically demanding movements in the gym. Poor squat technique limits your strength, places your knees and lower back at risk, and reduces the stimulus to the muscles you are trying to train. Mastering the squat is a worthwhile investment that pays dividends for your entire training career.

The Setup

Bar Position

There are two main bar positions: high bar and low bar. Both are valid, and your choice depends on your anatomy, goals, and comfort.

High bar places the barbell on top of the trapezius muscles, roughly at the base of the neck. This position is more upright, emphasizes the quadriceps, and is the default position in most gyms and in Olympic weightlifting.

Low bar places the barbell across the rear deltoids and the spine of the scapula, roughly 2 to 3 inches lower than high bar. This position creates a more forward lean, shifts more work to the posterior chain (glutes and hamstrings), and generally allows heavier loads. It is the preferred position in powerlifting.

If you are new to squatting, start with high bar. It is more intuitive and requires less shoulder mobility.

Grip and Upper Back

Grip the bar as narrow as your shoulder mobility allows while keeping your wrists straight. A narrower grip creates more upper back tightness, which creates a more stable shelf for the bar. Squeeze the bar hard and pull it into your back.

Drive your elbows down and slightly forward (for high bar) or down and back (for low bar). This engages the lats and upper back, creating the tightness that keeps the bar from shifting during the squat.

Unracking the Bar

Stand directly under the bar with it positioned on your back. Take a deep breath, brace your core, and stand up to unrack. Take 2 to 3 short steps back: one step to clear the hooks, one or two steps to set your stance. Avoid long walks backward. Every step uses energy and increases instability.

Foot Position

Set your feet roughly shoulder width apart, with toes pointed out 15 to 30 degrees. The exact stance width and toe angle depend on your hip anatomy. Some people squat best with a wider stance, others with narrower. The general rule is that your knees should track over your toes throughout the movement.

Your entire foot should maintain contact with the floor. Feel pressure distributed across three points: the big toe, the little toe, and the heel. If your weight shifts to your toes, you will lean forward. If it shifts entirely to your heels, you may fall backward.

The Descent

Initiate the Movement

For high bar squats, initiate by simultaneously bending at the hips and knees, sitting straight down between your legs. For low bar squats, initiate by pushing your hips back slightly first, then bending the knees as you descend.

The descent should feel controlled and deliberate. Do not drop quickly into the bottom position, but do not lower yourself so slowly that the eccentric becomes exhausting before you reach depth.

Knee Tracking

Your knees should travel forward and outward, tracking over the line of your toes throughout the descent. Do not let your knees cave inward (valgus), which stresses the ligaments and reduces force production.

The cue to push your knees out over your toes is one of the most important squat cues. It engages the glutes, opens the hips for depth, and protects the knee joint.

Depth

Full depth means the crease of your hip drops below the top of your knee (below parallel). This is the standard for a competition squat in powerlifting and the standard you should aim for in training.

Squatting to depth ensures you train the muscles through their full range of motion and prevents the development of partial-range strength that breaks down at depth. Half squats and quarter squats develop less overall strength and leave the glutes and hamstrings understimulated.

If you cannot reach depth, the solution is mobility work, not accepting a shorter range of motion. Ankle dorsiflexion, hip flexor flexibility, and hip capsule mobility are the most common limiters.

Bracing

Before descending, take a deep breath into your belly (not your chest), brace your core as if you are about to be punched in the stomach, and hold this brace throughout the rep. This intra-abdominal pressure stabilizes your spine and allows you to transmit force efficiently between your lower and upper body.

For heavy squats, a weightlifting belt augments this bracing by giving your abs something to push against, further increasing intra-abdominal pressure. Belts are a tool, not a crutch. Learn to brace properly without a belt before adding one.

The Ascent

Drive Out of the Hole

The transition from descent to ascent, called the hole, is the most challenging part of the squat. As you reach depth, reverse direction by driving your feet into the floor, pushing your back into the bar, and leading with your chest.

Think about pushing the floor away from you rather than lifting the bar. This cue keeps you from rising onto your toes and promotes full-body engagement.

Maintain Position

As you ascend, your torso angle should stay consistent. A common error is the hips shooting up faster than the shoulders, which turns the squat into a good morning. If this happens, the weight is likely too heavy, your core is not bracing effectively, or your quadriceps are underdeveloped relative to your posterior chain.

Drive your upper back into the bar and think about standing tall as you ascend. The bar, shoulders, and hips should rise at the same rate.

Lockout

Complete the rep by standing fully erect with knees and hips locked. Do not stop short of lockout. Full extension at the top ensures the rep is complete and gives you a moment to reset your breath and brace for the next repetition.

Common Squat Mistakes

Knees Caving In

This is the most common and most dangerous squat fault. Knee valgus places enormous stress on the ACL and meniscus and significantly reduces your force production. Focus on pushing your knees out over your toes. Strengthening the glutes with exercises like banded squats, hip thrusts, and clamshells helps correct this pattern.

Good Morning Squats

When your hips rise faster than your shoulders, the squat turns into a hip-dominant good morning. This overloads the lower back and underloads the quadriceps. Causes include weak quads, insufficient core bracing, and too much weight. Reduce the weight and focus on maintaining chest position.

Butt Wink

Excessive posterior pelvic tilt at the bottom of the squat, where your tailbone tucks under, can stress the lumbar spine under load. A small amount is normal and unavoidable for most anatomies. Excessive butt wink is often caused by limited ankle dorsiflexion or hip mobility. Address these limitations with targeted mobility work.

Forward Lean Onto Toes

Weight shifting to the toes causes you to lean forward and lose balance. This is usually caused by poor ankle mobility, insufficient core bracing, or a bar position that is too high for your proportions. Elevating your heels with squat shoes or thin plates under your heels can help while you develop ankle mobility.

Not Reaching Depth

Cutting squats short is often a compensation for limited mobility or excessive weight. Prioritize depth over load. A full-depth squat with lighter weight provides better training stimulus than a heavy half squat.

Improving Squat Mobility

Ankle Dorsiflexion

Perform wall ankle stretches: face a wall with one foot forward, bend your knee to touch the wall, and gradually increase the distance from wall to foot. Three sets of 30-second holds per side, performed daily, produces noticeable improvement within 2 to 3 weeks.

Squat shoes with a raised heel (typically 0.5 to 1 inch) effectively compensate for ankle mobility limitations and are a worthwhile investment for serious lifters.

Hip Mobility

The 90/90 stretch, pigeon pose, and deep goblet squat holds (sitting in the bottom of a squat with a light dumbbell for 30 to 60 seconds) all improve hip mobility for squatting. Perform these daily, especially before squat sessions.

Thoracic Extension

A rounded upper back collapses under heavy loads. Foam rolling the thoracic spine and performing cat-cow stretches improve the extension needed to maintain an upright torso under the bar.

Programming the Squat

For beginners, squat 2 to 3 times per week with 3 sets of 5 reps, adding 5 pounds each session. For intermediate lifters, squat 2 times per week, using a heavier day (4 sets of 4 to 6) and a lighter day (3 sets of 8 to 10). For advanced lifters, periodize squat training across mesocycles, alternating between volume, intensity, and peaking phases.

Regardless of your experience level, the squat rewards consistent practice and relentless attention to technique. Master the basics, address your mobility limitations, and progress patiently. The strength will follow.
