Low Bar Squat: Form, Bar Placement & Benefits

Bill Starr built his legendary programs around the back squat, and his approach to squatting remained consistent with old-school strength training. For his broader philosophy on squat variations, see Squat Variation by Bill Starr.

What Is the Low Bar Squat?

The low bar squat gets its name from where the bar sits on your back. Instead of resting high on the traps as in a high bar squat, the low bar position places the bar across the rear deltoids, allowing you to lean forward more and shift more of the load onto your hips and hamstrings. This makes the low bar squat a favorite for powerlifters and anyone chasing a bigger back squat.

The low bar position changes the mechanics of the squat: a more horizontal torso and a greater hip hinge. While this can be harder to learn, it typically allows heavier loads than a high bar squat.

Low Bar Squat Bar Placement

The key to a good low bar squat is correct bar placement. The bar should rest on the meaty shelf created by your rear delts when you squeeze your shoulder blades together, about two to three inches lower than a high bar position. Your hands grip the bar a bit wider than your shoulders to create a stable shelf, and your elbows point back rather than down.

Once in position, the bar should not slide or roll. Keeping your upper back tight and your elbows up holds the bar firmly against your rear delts for the whole set.

Low Bar Squat Form: Step by Step

1. Setup

Set the bar at about chest height in the rack and get under it. Squeeze your shoulder blades together to create a tight shelf on your rear delts. Grip the bar wider than shoulder-width and point your elbows back.

2. Unrack

Stand up with the bar and take one or two steps back. Set your feet shoulder-width apart with toes turned out slightly. Brace your core hard.

3. Descend

Push your hips back and break at the knees simultaneously, sitting down and back. Keep your chest up and your bar path over your midfoot. Descend until your hips are just below parallel.

4. Drive

Drive through your whole foot, pushing the floor away while keeping your chest up. Extend your hips and knees together until you stand tall.

Muscles Worked by the Low Bar Squat

Glutes: The primary hip extensors that drive you out of the bottom
Hamstrings: Loaded heavily by the forward lean and hip hinge
Quadriceps: Extend the knee and carry a large share of the load
Adductors: Stabilize the hip and help drive the knees out
Lower back and core: Braced to keep your torso rigid under heavy load

Low Bar Squat Benefits

Heavier loads: The shortened moment arm typically lets you lift more than a high bar squat.
Posterior chain development: Shifts emphasis onto the glutes and hamstrings.
Better for powerlifting: The low bar position is the standard for competition squats.
Less knee stress: A more horizontal torso reduces the forward knee travel compared to a high bar squat.

Low Bar vs High Bar Squat

The main difference is bar placement, which changes your torso angle and muscle emphasis. The low bar squat leans forward more and loads the hips and hamstrings; the high bar squat stays more upright and emphasizes the quads. Choose based on your goals and body mechanics.

Common Mistakes to Avoid

Bar too high: If the bar sits on your traps, you are high bar squatting. Keep it low on the rear delts.
Rising chest too early: Let your hips lead out of the hole instead of trying to keep an upright torso.
Not squeezing the shoulder blades: A loose shelf lets the bar slide and puts strain on your wrists and elbows.

How to Program the Low Bar Squat

Bill Starr's classic programming used the back squat as a core lift trained multiple times per week. In his original 5x5, the squat is trained three days per week. See Bill Starr 5x5 Program.

Frequently Asked Questions

Is the low bar squat better than the high bar squat?

Neither is inherently better — they shift emphasis differently. The low bar squat allows heavier loads and more posterior chain work; the high bar squat emphasizes the quads and a more upright posture. Choose based on your goals.

Why does the low bar squat hurt my wrists?

Wrist pain usually comes from placing the bar too high or gripping too narrow, which forces your wrists to bear weight. Squeeze your shoulder blades together, use a wider grip, and keep your wrists straight.
