Bulgarian Split Squat
The Bulgarian Split Squat is an advanced unilateral lower body exercise performed with one foot elevated behind you on a bench, challenging single-leg strength, balance, and stability while reducing lower back stress. This intermediate to advanced movement is ideal for athletes, strength enthusiasts, and those seeking improved unilateral leg strength and functional movement capability. The elevated rear foot position increases demand on the front leg while promoting proper movement mechanics.
NASM's evidence-based approach emphasizes unilateral training for identifying and correcting strength imbalances. The Bulgarian split squat improves single-leg strength, corrects asymmetries, and translates to improved athletic performance and functional leg capability.
How to Perform the Bulgarian Split Squat
Step 1: Setup
Stand facing away from a bench positioned behind you. Place one foot elevated on the bench with toes pointing downward, and position your other foot forward with weight distributed across your foot.
Step 2: Brace/Position
Engage your core and maintain upright posture. Position your hands on your hips or holding dumbbells at your sides for additional resistance. Prepare for controlled descent into the squat.
Step 3: Execute/Drive
Descend into a squat by bending your front knee and hip, keeping your chest upright and your weight centered over your front leg. Descend until your front thigh is approximately parallel to the floor.
Step 4: Return/Descent
Drive through your front leg to stand upright, maintaining postural control and balance throughout. Complete all repetitions on one leg before switching to the other leg for balanced development.
Muscles Worked
Primary Muscles:
- Quadriceps – primary mover for knee extension of the front leg
- Glutes – assist in hip extension and provide stability for the front leg
Secondary Muscles:
- Hip Stabilizers
- Core Stabilizers
- Hamstrings
- Adductors
Common Mistakes
- Using excessive weight that compromises balance or allows excessive forward lean
- Allowing the front knee to cave inward (valgus), indicating poor motor control
- Leaning excessively forward, which shifts weight distribution and increases lower back strain
- Not descending to adequate depth, which limits lower body stimulus
- Excessive reliance on upper body movement for balance rather than core stability
Bulgarian Split Squat Variations
As part of NASM's evidence-based approach to movement and strength training, the bulgarian split squat reinforces proper movement mechanics essential to long-term performance and injury prevention. NASM-certified personal trainers use the Optimum Performance Training (OPT) model to integrate exercises like the bulgarian split squat into individualized programs based on each client's assessment results.

Bulgarian Split Squat Exercise FAQs
What muscles do Bulgarian split squats work?
The Bulgarian split squat primarily targets the quadriceps and glutes of the front leg. It also engages the hamstrings, adductors, hip stabilizers, and core muscles to maintain balance, stability, and proper movement throughout the exercise.
Are Bulgarian split squats better than regular squats?
Bulgarian split squats emphasize unilateral strength, balance, and stability, making them effective for identifying and correcting leg-strength asymmetries. Traditional squats allow greater overall loading and bilateral strength development. Both exercises can be valuable components of a lower-body training program.
What are the benefits of Bulgarian split squats?
Bulgarian split squats help build lower-body strength, improve balance and stability, support functional movement, and address muscle imbalances between limbs. They can also provide a challenging leg workout while placing less stress on the lower back than some bilateral lower-body exercises.
