How to do a Bulgarian split squat
How to perform the Bulgarian split squat — foot placement, stance length, torso angle — plus how to bias quads or glutes, and how to stop falling over on rep one.
- The top — front shin vertical, rear foot on the bench, torso upright.
- The bottom — rear knee close to the floor, front knee tracking over the foot.
- Primary muscles
- quadriceps
- Also works
- glutes and hamstrings
- Equipment
- dumbbell
- Type
- compound, lunge
- Level
- intermediate
- Also called
- Bss, Bulgarian Split Squat, and Rear Foot Elevated Split Squat
The Bulgarian split squat is the most disliked effective leg exercise in the gym. It exposes exactly how much stronger one leg is than the other, it demands balance before it demands strength, and it makes a 20kg pair of dumbbells feel like a heavy squat.
That is also why it is worth doing. Bilateral squatting lets a strong side quietly carry a weak one for years. Splitting the stance removes that option, builds quads and glutes at loads your spine barely notices, and tends to help knees rather than bother them.
The set-up
- Stand about two feet in front of a bench or a low box — knee height or a little below. Too high and the setup becomes a hip flexor stretch.
- Place the top of your rear foot on the bench, laces down. Resting on the toes instead is fine and some people find it more stable — pick one.
- Check your stance length by dropping into the bottom position once. Your front shin should be roughly vertical and your rear knee should reach near the floor without your front heel lifting. Adjust and try again.
- Hold dumbbells at your sides, or a barbell on your back once balance is no longer the limiting factor.
- Brace your abs and set your torso — upright biases the quads, a slight forward lean biases the glutes.
The rep
- Lower by bending the front knee, letting the rear knee travel down toward the floor.
- Keep your weight through the front foot — mostly the midfoot and heel. The rear leg is a kickstand, not a second leg.
- Descend until your rear knee is just above the floor, or as deep as you can go with the front heel flat.
- Drive up through the front foot. Do not push off the rear toes.
- Finish just short of locking the front knee, keep the tension, and repeat. Complete all reps on one side before switching.
Common mistakes
- A stance that is too short
- The most common setup error. A short stance forces the front knee far past the toes and turns the exercise into a quad-only movement with the front heel lifting. If your heel comes up, step further forward.
- Pushing off the back foot
- The rear leg is there for balance. If it is driving, you are doing a slightly awkward bilateral squat and the point of the exercise is gone. Think about the rear foot as barely touching.
- Going heavy before you can balance
- Wobbling means the stabilisers are the limit, not the quads, so more weight just makes the wobble worse. Hold a rack or a wall with one hand for the first few sessions if you need to.
- Doing the strong leg first and matching it
- Everyone has a weaker side. If you lead with the strong leg and then match the number, the weak side trains to failure and the strong one does not — which at least keeps them from diverging further, but a better rule is to lead with the weaker leg and match that.
Sets and reps
Because the load is per-leg and the balance demand is high, this lives in the 8–12 range. It is far less systemically fatiguing than back squats, so it fits well late in a leg session or on a second lower body day.
| Goal | Prescription | Notes |
|---|---|---|
| Muscle | 3 sets of 8–12 per leg | Dumbbells. Control the descent — this is not a rep to rush. |
| Fixing an imbalance | 3 sets, weak side first | Match the strong side to the weak side's reps, not the other way around. |
| First year lifting | 2–3 sets of 10 per leg | Bodyweight until you can do it without holding anything. |
Variations worth knowing
- Back squat
- The bilateral version, with far more absolute load and a much larger recovery cost. These complement each other rather than compete.
- Walking lunge
- Same single-leg pattern, moving. Less stable, more conditioning, and easier on people who find the rear-foot-elevated position uncomfortable.
- Front squat
- Bilateral and quad-dominant with an upright torso. A good pairing when you want quad work with a barbell.
Questions
How far should my front foot be from the bench?
Far enough that at the bottom your front shin is close to vertical and your front heel stays flat. Around two feet suits most people, but check it by trying a rep rather than measuring. Too short is far more common than too long.
Why do I fall over doing Bulgarian split squats?
Because your stabilisers are the limiting factor before your legs are — which is normal and improves quickly. Hold a rack with one hand, widen your stance slightly side to side so your feet are not on a tightrope, and use lighter dumbbells for the first few weeks.
Do they work quads or glutes?
Both, and you can shift the balance. A more upright torso with a shorter stance biases the quads; a slight forward lean with a longer stance biases the glutes and adductors. Neither version leaves the other untrained.
How high should the bench be?
Knee height or a little below. Higher forces the hips into more extension than most people have available, which is what makes some lifters feel this in the front of the hip rather than the leg.
Are they better than regular squats?
Not better — different. Back squats let you load far more weight and build overall strength; split squats find and fix the side-to-side differences that back squats hide, at a fraction of the spinal load. Most good programs have both.
How do I log a unilateral exercise?
Record the weight per hand and the reps per leg, and keep it consistent so the numbers stay comparable. Workout Chat knows which catalogue movements are unilateral, so a Bulgarian split squat is charted as its own progression and not accidentally compared against your back squat.
Log it the moment you rack it.
Type “bulgarian split squat 3x5 at 80kg” and it's recorded, charted, and checked against your best.
