Bulgarian Split Squat: Form, Foot Position, Glutes vs Quads
Published October 20, 2026
The Bulgarian split squat is a single-leg squat with your rear foot elevated on a bench: you lower your back knee toward the floor and push back up through your front foot. It builds quads and glutes, fixes left-right imbalances and needs far less load than a barbell squat to be hard, which makes it ideal at home or in a crowded gym.
Setup and form
- Bench height: about knee height (16-20 in / 40-50 cm).
- Rear foot: laces down on the bench (or toes, whichever is comfortable).
- Front foot distance: lunge out about 2-3 feet (60-90 cm) from the bench; adjust so the front heel stays down at the bottom.
- Lower straight down until the back knee is a few inches from the floor.
- Front knee tracks over the toes; it can move forward.
- Drive up through the whole front foot.
Glutes or quads? Change the angle
| Goal | Torso | Front foot | Feel it in |
|---|---|---|---|
| More glutes | Lean forward ~30-45° | Further from the bench | Glutes, adductors |
| More quads | Upright torso | Closer to the bench | Front of thigh |
Is it as good as the back squat?
In academy rugby players, single-leg squat training produced similar gains in strength, sprint speed and change-of-direction ability as bilateral squats (Speirs et al., 2016). It is a real alternative, not just an accessory.
Weights to start with
| Level | Load (per hand) | Reps |
|---|---|---|
| Beginner | Bodyweight | 3 × 8-10/leg |
| Intermediate | 15-35 lb (7-16 kg) dumbbells | 3 × 8-12/leg |
| Advanced | 40-70 lb (18-32 kg) or barbell | 3-4 × 6-10/leg |
Common mistakes
| Mistake | Fix |
|---|---|
| Front heel lifts | Move the front foot further out |
| Wobbling | Hold a rack with one hand, use a lighter load |
| Pushing off the back foot | Back leg is just a kickstand |
| Knee caving inward | Push the knee out over the middle toes |
| Bouncing off the bottom | 2-second lower, brief pause |
6-week progression (twice a week)
| Weeks | Prescription |
|---|---|
| 1-2 | Bodyweight 3 × 10/leg, 3-second lowering |
| 3-4 | Dumbbells 3 × 10/leg, 2 reps in reserve |
| 5-6 | Heavier dumbbells 4 × 8/leg |
Add weight when you hit the top of the range on every set. Start each set with your weaker leg and match reps on the other side.
Where it fits
| Day | Placement |
|---|---|
| Leg day | After squats or as the main lift |
| Home workout | Main leg exercise |
| Runners | 2 × week for single-leg strength (see strength training for runners) |

FAQ
Why is it so hard? You carry most of your weight on one leg in a long range of motion; soreness the first weeks is normal (see DOMS).
Knee pain? Reduce depth, move the front foot out, and see a physical therapist if it persists.
