Bulgarian Split Squat

Stand about two feet in front of a bench, holding a dumbbell in each hand. Place the top of your rear foot on the bench behind you. Lower your body by bending your front knee until your rear knee nearly touches the floor, keeping your torso upright. Drive through your front foot to return to the starting position.

Pro Tips

• Keep your front shin roughly vertical — knee should not drift far past your toes
• An elevated rear foot increases range of motion and quad stretch compared to regular lunges
• Start with bodyweight only to master balance before adding dumbbells

Muscles worked

Primary: Quadriceps of the front leg — the elevated rear foot increases the hip-flexor stretch and forces the front leg to do more of the work than a standard lunge, creating a higher quad stimulus per repetition.

Supporting: Gluteus maximus (hip extension of the front leg, especially as the torso stays upright), hamstrings (stabilisation of the front knee), adductors (inner thigh stabilisation throughout), hip flexors of the rear leg (under passive stretch throughout the movement), core (balance and torso stability).

Common mistakes

Front foot too close to the bench: If the front foot is placed too close, the shin becomes very vertical and the movement turns into a knee-dominant exercise with limited hip involvement. The front foot should be far enough forward that the shin remains roughly vertical at the bottom.

Front knee caving inward: Valgus collapse at the front knee (knee tracking inside the foot) indicates hip abductor weakness or excessive load. Push the knee out in line with the toes throughout.

Rising onto the toes at the bottom: As the rear knee approaches the floor, the tendency is to let the front heel rise. Keep the front foot flat and the heel grounded throughout — it is the driver of the press back up.

Loading too fast: Balance is the limiting factor early in the learning curve, not strength. Adding dumbbells before the movement pattern is stable creates a combined learning and loading problem. Bodyweight first, then load.

Programming notes

The Bulgarian split squat is one of the most effective unilateral lower body exercises and produces comparable quad and glute stimulus to the barbell back squat while also exposing bilateral strength imbalances. Because each leg is trained independently, a lifter cannot compensate with a stronger limb.

In hypertrophy programmes, it typically appears as a secondary leg exercise after bilateral squats, for 3–4 sets of 8–12 repetitions per leg. In programmes that emphasise injury resilience or single-leg strength (athletes, post-rehab), it sometimes serves as a primary lower body exercise alongside or instead of bilateral squatting.

Frequently asked questions

How far should my front foot be from the bench?

Step far enough forward that your front shin stays roughly vertical when your rear knee reaches the floor. A good starting point is roughly two to three feet. If your knee shoots well past your toes at the bottom, you are too close; if you feel you are lunging straight down rather than forward, you are too far. Use a few unloaded reps to dial in your stance before adding weight.

Is the Bulgarian split squat bad for your knees?

Not inherently — the exercise places significant load on the knee joint but no more than a well-executed barbell squat. Problems arise when the front foot is placed too close (excessive forward knee travel under load), the front heel lifts (shifting load onto the forefoot and disrupting tracking), or the weight is increased faster than balance and technique allow. Control those three variables and the Bulgarian split squat is a knee-friendly exercise for most lifters.

Should I do it before or after bilateral squats?

After, in the vast majority of programmes. Bilateral squats — back squat, front squat, goblet squat — are the primary lower-body movement and should be performed when you are freshest. The Bulgarian split squat then functions as an accessory that adds unilateral volume and addresses imbalances without competing for your best sets. The exception is a programme built specifically around single-leg strength, where it may serve as the primary movement in its own right.
