Bulgarian Split Squat

What is the Bulgarian Split Squat?

The Bulgarian split squat is a single-leg squat with the rear foot elevated on a bench, so nearly all the load falls on the front leg. Elevating the trailing foot removes it as a crutch and forces the working quad through a long, controlled range, making it one of the best unilateral quad and glute builders and a favorite for evening out left-to-right imbalances.

Muscles worked

Primary: Quads

The quadriceps of the front leg are the prime mover, extending the knee to drive you up out of a deep lunge position with almost none of the load shared by the elevated rear leg.

Secondary: Glutes, Hamstrings

The glutes of the front leg contribute hip extension out of the bottom, and the hamstrings assist at the hip and help control the descent.

Stabilizers

The trunk and the hip stabilizers of the front leg work hard isometrically to keep you balanced over a narrow single-leg base.

How to perform the Bulgarian Split Squat

1. Stand about a stride's length in front of a bench; place the top of the rear foot on the bench with the shoelaces down (or the toes pointed, whichever is more comfortable).
2. The front foot should be far enough forward that, at the bottom of the rep, the front shin is roughly vertical. Adjust the stance until this is true.
3. Hold a dumbbell in each hand at your sides, brace your core, and keep your torso roughly upright (a slight forward lean is fine for more glute emphasis).
4. Lower yourself by bending the front knee and dropping the rear knee toward the floor; keep most of your weight on the front foot, with the rear leg acting as a kickstand.
5. Descend until the rear knee lightly touches the floor or comes within an inch of it, keeping the front knee tracking over the toes.
6. Drive up through the front foot, keeping the front knee stable and not letting it collapse inward; finish each rep with the hip extended but the rear leg still on the bench.

Suggested working range: 8–12 reps. Default progression: double progression.

Mechanics

A unilateral lunge-pattern squat: the front knee bends and travels forward to lower the hips straight down, then the front quad and glute extend the knee and hip to stand back up, while the rear foot on the bench only balances. As a compound single-leg movement it demands both strength and stability, and the elevated rear leg lets the front hip drop into a deeper range than a standing split squat.

Form cues

• •Set your front foot far enough forward that at the bottom the front shin stays roughly vertical to slightly angled and the knee tracks over the toes, not caving inward.
• •Lower straight down until the rear knee approaches the floor, keeping most of your weight through the front heel and midfoot.
• •Keep the torso tall with a braced trunk; a slight forward lean is fine, but don’t collapse the chest toward the front thigh.

Common mistakes

• •Setting the front foot too close to the bench so the front knee tracks far past the toes and most of the work shifts to the knee.
• •Letting the front knee collapse inward on the way up out of the bottom.
• •Bouncing the rear knee off the floor to bounce out of the bottom of the rep.
• •Leaning the torso so far forward that the lift becomes a single-leg good morning rather than a split squat.

Variations & alternatives

• •Goblet squat: a bilateral quad builder to fall back on when balance limits how hard you can push the split squat.
• •Walking lunge: the same single-leg pattern moving through space instead of stationary with an elevated rear foot.
• •Barbell back squat: the heavy bilateral squat this movement complements as unilateral accessory work.

Programming: sets, reps & when to use it

Run the Bulgarian split squat in the 8–12 rep range per leg as a primary or secondary quad and glute movement, using dumbbells you can control without wobbling. Because it’s unilateral, count reps per leg and start each set with your weaker side so it sets the working volume.
