How to do Bulgarian Split Squat
- 1
Stand facing away from a bench, about one stride in front of it, and place the top of one foot on the bench behind you.
- 2
Set your front foot far enough forward that you can lower straight down with your whole front foot, heel included, staying flat on the floor.
- 3
Keep your torso upright and your core braced, with your hands on your hips or at your sides.
- 4
Lower your body by bending your front knee until your front thigh is about parallel to the floor, with your back knee hovering just above the ground.
- 5
Push through the whole front foot to stand back up to the starting position.
- 6
Complete all reps on one side before switching to the other leg.
Form cues
- Rest the top of your back foot, laces down, on the bench.
- Keep most of your weight on your front foot.
- Drop your back knee straight down toward the floor.
- Keep your front knee tracking over the middle of your foot.
- Drive through your whole front foot to stand up.
Breathing: Breathe in as you lower toward the floor, and breathe out as you drive back up through your front foot.
Common Bulgarian Split Squat mistakes
Front foot too close to the bench
Step farther forward so your front heel stays down and your knee isn't cramped at the bottom.
Feet in line like on a tightrope
Keep your feet about hip-width apart side to side for a steadier base.
Pushing up with the back leg
Treat the back foot as a kickstand for balance and drive through the front foot.
Front knee caving inward
Push your knee out in line with your toes and slow the descent.
Using a bench that's too high
Use a knee-height or lower surface so your back hip and thigh aren't overstretched.

Bulgarian Split Squat FAQ
What muscles does the Bulgarian split squat work?
It mainly works the quads and glutes of your front leg, which do most of the work to lower and lift you. The hamstrings and adductors help steady the hip, and the calves help with balance. The back leg mainly supports balance, and you'll often feel a stretch along the front of that hip and thigh.
Why are Bulgarian split squats so hard?
Your front leg carries most of your bodyweight on its own, you have to balance on a narrow base, and the bottom position puts the front leg through a deep range while the back hip stretches. That combination is why even bodyweight sets feel tough. Start with a short range and add depth and load gradually.
Should I lean forward on Bulgarian split squats?
Either is fine as long as your back stays flat. A more upright torso with the front foot a bit closer puts more work on the quads. A slight forward lean from the hips with the front foot a bit farther out shifts more work to the glutes. Pick the position that suits your goal and feels stable.
How far should my front foot be from the bench?
Roughly one long stride. A simple test is to lower to the bottom: your front heel should stay flat and your front shin should be roughly vertical to slightly forward. If your heel lifts or your knee feels jammed, step farther out; if you feel a strong pull on the back hip or lose balance, step closer.
Bulgarian split squat vs lunge: which is better?
The Bulgarian split squat keeps your feet fixed and your rear foot raised, so the front leg takes more of the load through a deeper range and it is easy to control. Lunges add a step, which trains balance and slowing down. Both build the quads and glutes; many programs use split squats for strength and lunges for variety.
