The barbell squat is one of the most effective compound exercises for building lower-body strength. It works several major muscle groups at the same time, including the quadriceps, glutes, hamstrings and core.
Whether your goal is to build muscle, increase strength or improve your overall fitness, learning proper squat technique is an excellent place to start.
Muscles Worked
The barbell squat primarily targets:
- Quadriceps
- Glutes
- Hamstrings
- Core
- Lower back
- Calves, to a lesser extent
What You Need
- Barbell
- Squat rack
- Appropriate weight plates
- Safety pins or spotter arms
- Proper training shoes
How to Perform a Barbell Squat
Step 1: Set Up the Bar
Place the barbell on the squat rack at approximately shoulder height. Step underneath it and position the bar comfortably across your upper back.
Avoid placing the bar directly on your neck.
Step 2: Position Your Feet
Step away from the rack and place your feet approximately shoulder-width apart. Your toes can point slightly outward.
Find a stance that allows your knees and hips to move naturally throughout the exercise.
Step 3: Brace Your Core
Before beginning the movement, take a deep breath and tighten your abdominal muscles. Keep your chest controlled and your spine in a neutral position.
Step 4: Lower Your Body
Begin by bending your knees and pushing your hips slightly backward.
Lower your body under control while keeping your feet firmly planted on the floor.
Continue lowering until your thighs reach approximately parallel to the floor, or as far as you can comfortably go while maintaining proper form.
Step 5: Stand Back Up
Push through the middle of your feet and heels to return to the starting position.
Keep your knees tracking in the same direction as your toes.
Recommended Sets and Reps
Beginners: 3 sets × 8–10 reps
Intermediate: 3–4 sets × 6–10 reps
Choose a weight that allows you to maintain good technique throughout every repetition.
Common Mistakes
Going Too Heavy
Using excessive weight can cause your technique to break down. Master the movement before increasing the load.
Knees Collapsing Inward
Your knees should generally track in line with your toes. Avoid allowing them to collapse toward each other.
Lifting Your Heels
Keep your feet firmly connected to the floor throughout the movement.
Rushing the Repetitions
Controlled repetitions allow you to maintain better positioning and develop strength more effectively.
Beginner Tip
If you’re new to squatting, start with bodyweight squats or a light goblet squat before progressing to a barbell.
Final Thoughts
The barbell squat is a foundational strength exercise, but technique should always come before weight. Start light, learn the movement and gradually increase resistance as your confidence and strength improve.
