Barbell Full Squat: How to Do It, Muscles Worked

Last updated 26 July 2026

What muscles does the Barbell Full Squat work?

The Barbell Full Squat primarily targets the quadriceps, and also recruits the calves, glutes, hamstrings, lower back as secondary muscles. It's classified as a intermediate-level strength movement using barbell.

What are the most common Barbell Full Squat mistakes?

• Holding the breath and bracing incorrectly instead of using a proper intra-abdominal brace.
• Letting the heels lift off the floor, which shifts balance forward onto the toes.
• Letting the knees cave inward as the weight gets heavy, instead of tracking over the toes.
• Losing a neutral spine and rounding the lower back at the bottom of the rep.

How should I program the Barbell Full Squat — sets, reps and frequency?

As a lower-body compound lift, it responds well to a moderate-to-heavy 4-8 reps for 3-5 sets when trained for strength, or 8-12 reps for hypertrophy. Most lifters train it once or twice a week as a primary movement in a push/pull/legs or upper/lower split. Add small amounts of weight or an extra rep once every working set can be completed with good form — the same progressive overload principle behind every strength exercise in the library.

How to do the Barbell Full Squat, step by step:

1. Step 1. This exercise is best performed inside a squat rack for safety purposes. To begin, first set the bar on a rack just above shoulder level. Once the correct height is chosen and the bar is loaded, step under the bar and place the back of your shoulders (slightly below the neck) across it.
2. Step 2. Hold on to the bar using both arms at each side and lift it off the rack by first pushing with your legs and at the same time straightening your torso.
3. Step 3. Step away from the rack and position your legs using a shoulder-width medium stance with the toes slightly pointed out. Keep your head up at all times and maintain a straight back. This will be your starting position.
4. Step 4. Begin to slowly lower the bar by bending the knees and sitting back with your hips as you maintain a straight posture with the head up. Continue down until your hamstrings are on your calves. Inhale as you perform this portion of the movement.
5. Step 5. Begin to raise the bar as you exhale by pushing the floor with the heel or middle of your foot as you straighten the legs and extend the hips to go back to the starting position.
6. Step 6. Repeat for the recommended amount of repetitions.
