Overview

The classic barbell squat, also known as the back squat, is a foundational compound exercise that builds lower body strength, power, and muscle mass. Performed with the barbell across the upper back, it demands full-body coordination and proper form to maximize effectiveness while minimizing injury risk.​

Target Muscle Groups

• Primary: Quadriceps, Glutes, Hamstrings

• Secondary: Core (abs, obliques), Lower back (erector spinae), Adductors, Calves​

How to Perform Classic Barbell Squat

Setup

1. Position barbell at mid-chest height in squat rack.

2. Duck under bar, place across rear deltoids/traps (not neck), grip slightly wider than shoulders.

3. Lift elbows under bar, squeeze upper back, unrack and step back.

4. Feet shoulder-width apart, toes slightly out (15-30°).​

Execution Steps

1. Brace core with deep breath, chest up, eyes forward.

2. Initiate by pushing hips back, bending knees simultaneously.

3. Lower until hips below knees (parallel or deeper if mobile).

4. Drive through midfoot/heels to stand explosively.

5. Fully extend hips/knees at top without locking out.

6. Repeat controlled reps; rerack safely.​

Tips for Proper Form

• Maintain neutral spine; avoid rounding or excessive arching.

• Keep knees tracking over toes (push knees out).

• Bar over midfoot throughout movement.

• Breathe in on descent, brace and exhale through ascent.

• Use safety bars for heavy sets.​

Common Mistakes to Avoid

• Knees caving inward (valgus collapse).

• Excessive forward lean or butt wink at bottom.

• Heels lifting off floor.

• Bar too high on neck causing pain.

• Partial depth sacrificing range.​

Benefits

• Maximum lower body strength and hypertrophy.

• Boosts athletic performance and power output.

• Improves core stability and posture.

• Enhances mobility and functional movement.

• High hormone response for muscle growth.
