The barbell low split squat is a single-leg strength exercise that works the quadriceps and glutes of the front leg while the rear leg supports and balances the movement. Performed in a deep, low staggered stance with a barbell across your upper back, it builds lower-body strength, stability, and balance one leg at a time.
How to do the Barbell Low Split Squat
- 1Set a barbell at upper-chest height in a rack and position the bar across your upper back (traps), gripping it slightly wider than shoulder-width.
- 2Unrack the bar, step back, and take a long staggered stance — one foot forward, the other foot well behind you with the heel lifted.
- 3Brace your core and keep your torso upright with your weight centered between both feet.
- 4Bend both knees to lower into a deep, low position until your front thigh is roughly parallel to the floor and your rear knee tracks down toward the ground.
- 5Keep your front knee tracking in line with your toes and your front heel flat on the floor.
- 6Drive through your front foot to extend both legs and return to the tall split-stance start position.
- 7Complete all your reps on one side, then switch legs and repeat for the same number of reps.
- 8Step forward into the rack and re-rack the bar safely with control.
Form tips
- Keep your front shin relatively vertical and your knee tracking over your toes to keep tension on the quads and glutes rather than the joint.
- Stay tall through your chest and brace your core so the bar stays balanced over your mid-foot throughout the rep.
- Control the descent into the low position rather than dropping into it, then drive up smoothly through the front heel.
- Set the safety arms in the rack or have a spotter ready when loading heavy, since balancing a barbell on one leg is less stable than a two-legged squat.
- Find a fixed point to look at ahead of you to help hold your balance through the full range of motion.
Common mistakes
- Letting the front knee cave inward, which shifts load off the working muscles and stresses the knee joint.
- Leaning the torso too far forward, which dumps the work onto the lower back and reduces tension on the quads and glutes.
- Taking too short a stance, which forces the front knee far past the toes and limits how deep and stable the low position can be.
- Pushing off the rear foot instead of driving through the front leg, which cheats the rep and removes load from the target leg.
- Going heavier than your balance allows, which breaks form and makes the lift unsafe before the muscles are the limiting factor.
Frequently asked questions
What muscles does the barbell low split squat work?
It mainly works the quadriceps and glutes of the front leg, while the rear leg helps support and stabilize the movement. As a single-leg lift, it also challenges your core and balance more than a regular barbell squat.
How wide or long should my stance be?
Use a long front-to-back stance so your front shin can stay near vertical at the bottom while your rear knee drops toward the floor. Keep your feet about hip-width apart side-to-side for balance.
Is the barbell low split squat good for beginners?
It is a more advanced variation because balancing a loaded barbell on one leg takes practice. Beginners should master a bodyweight or dumbbell split squat first, then add a light barbell once the movement feels stable.
How many sets and reps should I do?
For strength and muscle, 3 to 4 sets of 6 to 10 reps per leg is a solid range. Keep the weight light enough that you stay balanced and in control on every rep.
What's a good alternative to the barbell low split squat?
Dumbbell split squats, Bulgarian split squats, and barbell lunges train the same single-leg quad and glute pattern. Dumbbells are easier to balance and a good way to build up to the barbell version.
