- Set your feet about shoulder-width apart, with toes turned slightly outward.
- Inhale and brace your trunk before bending your hips and knees together.
- Lower until your thighs approach parallel, keeping your whole feet planted.
- Push through both feet to stand, letting your hips and chest rise together.
- Exhale near the top, then reset your brace before each repetition.

Frequently Asked Questions
What does Barbell Back Squat work?
Barbell Back Squat targets your glutes and quads as the primary movers. Your hamstrings also kick in to assist the movement. It is one of the most popular exercises for glutes training. You will need a barbell for this one.
What is the most common mistake with Barbell Back Squat?
The biggest mistake is letting your lower back take over instead of squeezing through your glutes. Slow down, focus on feeling the glutes work through the full range of motion, and use a weight or difficulty level you can actually control.
How many sets and reps should I do for Barbell Back Squat?
Start with 3 sets of 10 to 15 reps. If the exercise works one side at a time, do 10 to 15 reps per side. Rest 30 to 60 seconds between sets. Pick a weight that makes the last 2 to 3 reps feel challenging but doable with good form. Track your sets in the FitAI app to make sure you are progressing over time.
What can I do instead of Barbell Back Squat if I don't have a barbell?
You can substitute dumbbells or a heavy resistance band and still target your glutes effectively. The key is keeping the same movement pattern and range of motion. The resistance source matters less than how you control the movement.
