Are you ready to master the Squat? This guide will teach you everything you need to know about this foundational strength exercise. The Barbell Squat is often called the "king of all exercises" for good reason. It builds strength throughout your entire body, increases athleticism, and carries over to countless real-world activities. Whether you're looking to build muscle, increase strength, or improve athletic performance, the squat deserves a place in your training program. When performed correctly, it's one of the most effective exercises for developing lower body power. This guide covers proper technique, common mistakes, effective variations, and programming recommendations to help you get the most out of your squats.

Why the Squat Is Worth Mastering

The Squat is more than just another leg exercise in your arsenal. It's a fundamental movement that:

Builds Total-Body Strength

Engages over 200 muscles, making it one of the most efficient exercises for overall strength development.

Increases Athletic Performance

Enhances jumping ability, sprinting power, and overall athletic capacity by developing force production in the lower body.

Improves Functional Movement

Strengthens the exact movement pattern used in countless daily activities, from sitting down to lifting objects from the ground.

Proper Squat Form: Step-by-Step

Starting Position

Set the barbell at upper chest height on the rack and position it across your upper back (not on your neck).
Grip the bar with hands placed evenly outside your shoulders, elbows pointing down.
Unrack the bar, take 2-3 steps back, and set your feet shoulder-width apart with toes slightly turned out.

The Movement

Take a deep breath, brace your core, and initiate the movement by pushing your hips back first, then bending your knees.
Keep your chest up, back neutral, and knees tracking in line with your toes as you descend.
Lower yourself until your thighs are at least parallel to the floor (or deeper if mobility allows), then drive through your heels and mid-foot to stand back up.

Key Form Tips

Knee Tracking

Keep your knees in line with your toes, never caving inward.

Torso Position

Keep your chest up; avoid rising with the hips first ("good morning" squat).

Foot Pressure

Think about screwing your feet into the floor to engage your hips and maintain knee position.

Bar Path

Keep the bar moving in a vertical line over mid-foot.

Breathing

Inhale at the top, brace your core, hold during the movement, and exhale at the top.

Hip Drive

Focus on driving your hips forward as you rise to engage glutes properly.

Muscles Worked in the Squat

Primary Muscles

quadriceps: The quads are heavily engaged to extend the knee as you push back up from the bottom position.
glutes: The gluteus maximus is powerfully activated to drive hip extension, especially in the latter part of the upward movement.

Secondary Muscles

hamstrings: The hamstrings work eccentrically during the descent and assist with hip extension on the way up.
hip adductors: The inner thigh muscles help stabilize the hip and knee joints throughout the movement.
erector spinae: These back muscles work isometrically to maintain an upright torso position throughout the squat.
abdominals: The entire core musculature, including the abdominals and obliques, works to stabilize the trunk.

Common Mistakes and How to Avoid Them

Knees caving inward

Places stress on knee ligaments and reduces glute activation Fix it: Focus on pushing knees outward during the entire movement, think about "spreading the floor"

Rising with hips first (good morning squat)

Places excessive strain on the lower back Fix it: Keep chest up and focus on driving traps into the bar while maintaining a more vertical torso

Squat Variations

Beginner-Friendly Variations

Bodyweight Squat

Perform the squat movement pattern with just your bodyweight to master form and build base strength.
Goblet Squat

Hold a dumbbell or kettlebell at chest level to add resistance while promoting proper form and upright posture.

Advanced Variations

Front Squat

With the barbell held across the front of the shoulders, this variation increases the demand on the quadriceps and core while decreasing spinal loading.
Box Squat

Squatting to a box behind you teaches proper depth and helps develop explosive power out of the bottom position.
Pause Squat

Adding a 2-3 second pause at the bottom position increases strength and stability in the hardest part of the movement.

FAQs About the Squat

At minimum, you should descend until your thighs are parallel to the floor (hip crease at or below the top of the knee). However, if you have the mobility to squat deeper while maintaining a neutral spine and proper form, "ass-to-grass" squats offer additional benefits for muscle development and mobility.

Lifting belts can be beneficial for heavy sets by providing something to brace your core against. Beginners should learn proper bracing without a belt first, typically incorporating one only for sets above 80% of their 1RM. A belt is a tool to enhance performance, not a substitute for core strength or proper bracing technique.

Lower back pain often stems from losing the neutral spine position, typically by either overarching or rounding the lower back. Focus on proper bracing, avoid excessive forward lean, and ensure you're not going heavier than your current form allows. Recording your squats from the side can help identify position issues.

Tips from the Community

Eric Wagner

Take a deep breath and hold it during the descent and most of the ascent. This helps to stabilize your torso.
Sarah Wagner

Grip the bar hard. It lets your mind & body know you're in control.
Eric Wagner

Set your feet shoulder width apart with your toes angled slightly outward.
John Francis Cardwell

Start with your feet shoulder width apart. Point your toes to almost 45 degrees outward. Take a deep breath from your stomach and hold it. Pinch/tighten your shoulders, squeeze your glutes, unlock your hips and start the descent. At the bottom force your elbows forward, knees out and head up. Snake out your air and while coming up midway, push your hips forward.
Ben Metlis

Set the bar right on your traps or use a towel to reduce friction and for comfort.
