How to Do It
- Stand a large step in front of a bench, facing away from it, and rest the top of one foot on the bench behind you.
- Hold a dumbbell in each hand at your sides, or start bodyweight if balance is the limiting factor.
- Lower straight down until your front thigh is close to parallel with the floor and your back knee drops toward the ground.
- Keep most of your weight through your front heel and midfoot, not your back foot.
- Drive through your front leg to stand back up, keeping your torso close to upright.
- Complete all reps on one leg before switching sides.
Common Mistakes
- Placing the front foot too close to the bench, which shortens the range of motion and pushes the knee far past the toes.
- Letting the back foot carry too much weight, which turns the movement into a step-up instead of a single-leg squat.
- Losing balance sideways because the front foot is directly in line with the back foot instead of hip-width apart.
- Leaning forward excessively, shifting load off the quads and glutes and onto the lower back.
The Bulgarian split squat is one of the most effective single-leg exercises for building quad and glute strength, because the elevated rear foot lets the front leg move through a deeper range than a standard split squat allows, without needing extra load to feel challenging.[1][2]
Balance is usually the first obstacle, not strength. If you’re wobbling, start bodyweight and hold onto something for support until the position feels stable, then add dumbbells once you can complete a full set unassisted.
This exercise pairs well with a bilateral movement like the barbell back squat earlier in a session, using the Bulgarian split squat as a unilateral finisher to correct side-to-side strength imbalances. It’s a staple accessory on leg day programs and works just as well with dumbbells at home as it does in a gym. If balance or a bench isn’t available, the goblet squat trains similar muscles with a much lower skill floor, and the leg extension is a useful machine-based way to add extra direct quad volume once the single-leg pattern feels solid.
Muscles Worked by the Bulgarian Split Squat
The Bulgarian split squat trains the quads and glutes hard as prime movers, with the hamstrings and adductors contributing more than in a standard bilateral squat because of the single-leg stance and deeper range.
- Primary: quadriceps, glutes
- Secondary: hamstrings, adductors
- Stabilizers: core and hip abductors, which work overtime to keep the pelvis level and prevent the front knee from caving inward under load[1][2]
Because the rear foot is elevated and carries almost no weight, the front leg absorbs close to your full bodyweight through the movement, which is why this exercise builds strength and stability that a two-leg squat doesn’t train the same way.
Bulgarian Split Squat vs Squat
Both exercises train the quads and glutes through a deep knee bend, but the Bulgarian split squat trains one leg at a time while the barbell squat loads both legs together. For a complete comparison of load ceilings, balance demands, and how to program both into a weekly routine, read our dedicated Bulgarian split squat vs squat guide.
Bulgarian Split Squat Alternatives
- Split squat: keeps the rear foot on the ground instead of elevated, a lower-skill regression that’s a good starting point before progressing to the Bulgarian version.
- Goblet squat: trades the single-leg balance demand for a simpler bilateral pattern that still builds quad and glute strength.[1][2]
- Leg extension: an isolation option for the quads when balance, not strength, is limiting how much load you can use.[1][2]
- Barbell back squat: the bilateral alternative for lifters chasing maximal load rather than unilateral stability.[1][2]
If balance is the main obstacle rather than strength, spend a few weeks on the regular split squat first: the Bulgarian version rewards a stable base far more than it rewards raw leg strength.[1][2]

Frequently Asked Questions
- How to do a Bulgarian split squat correctly?
- To do a Bulgarian split squat correctly, stand about two to three feet in front of a bench, place the top of your rear foot on the bench, and lower your hips straight down until your front thigh is parallel to the ground. Keep your front heel planted, torso upright with a slight forward lean, and drive through the midfoot to return to the starting position.
- What are common mistakes in Bulgarian split squats?
- Common Bulgarian split squat mistakes include standing too close to the bench, pushing off the back leg instead of loading the front leg, letting the front knee cave inward, and placing the front foot directly in line with the rear foot instead of maintaining hip-width distance, which causes instability.
- Are Bulgarians or RDLs better for glutes?
- Bulgarian split squats and Romanian deadlifts (RDLs) target the glutes differently and are complementary. Bulgarian split squats emphasize single-leg stability and deep glute stretch under knee flexion, while RDLs focus on hip hinge mechanics and loaded stretch under hamstring tension. Combining both provides complete glute development.
- What side do you put the weight on for Bulgarian split squat?
- You can hold a weight on either side depending on your focus. Holding a single dumbbell in the hand opposite your working front leg (contralateral) increases glute medius activation and core stability demand, while holding it on the working side (ipsilateral) offers slightly more balance control. Holding two dumbbells provides maximum load.
- What is the king of all exercises?
- The barbell squat and deadlift are traditionally called the kings of all exercises for building overall full-body strength and muscle mass. However, single-leg variations like the Bulgarian split squat are often considered the king of unilateral exercises due to their unmatched ability to correct imbalances, build leg strength, and enhance athletic performance.
- Why is Bulgarian squat so hard?
- The Bulgarian split squat feels harder than a regular squat because the rear-elevated foot removes the back leg's ability to share the load, forcing the front leg to support close to your full bodyweight through a deep range of motion while also balancing. That combined strength and stability demand is what makes it so demanding at a given weight.
- How do I know if I'm doing Bulgarian split squats correctly?
- You're doing Bulgarian split squats correctly if your front knee tracks in line with your toes rather than caving in, most of your weight stays through your front heel and midfoot rather than the rear foot, and your torso stays close to upright with only a slight forward lean throughout the descent and drive back up.
