How to perform Barbell Side Split Squat
- Stand up straight while holding a barbell placed on the back of your shoulders (slightly below the neck). Your feet should be placed wide apart with the foot of the lead leg angled out to the side. This will be your starting position.
- Lower your body towards the side of your angled foot by bending the knee and hip of your lead leg and while keeping the opposite leg only slightly bent. Breathe in as you lower your body.
- Return to the starting position by extending the hip and knee of the lead leg. Breathe out as you perform this movement.
- After performing the recommended amount of reps, repeat the movement with the opposite leg.
Muscles worked
- Quads (primary): extends the knee to drive squats, lunges and jumps.
- Calves (secondary): points the foot to power push-off and steady the ankle.
- Hamstrings (secondary): bends the knee and extends the hip through hinges and pulls.
- Core (secondary): braces the trunk and resists twisting to protect the spine.
Sets & reps by goal
| Goal | Sets × reps | Load | Rest |
|---|---|---|---|
| Strength | 3–5 × 3–5 | Heavy (~85%+) | 2–3 min |
| Hypertrophy | 3–4 × 8–12 | Moderate (~65–75%) | 60–90 s |
| Endurance | 2–3 × 15–20 | Lighter (~50–60%) | 30–45 s |
Pick the row that matches your goal. If you're newer, anchor in the hypertrophy range while you groove the form.
Form tips
- Keep the knees tracking in line with the toes and push the whole foot into the floor.
- Keep the bar path close and stacked over your mid-foot; letting it drift forward wastes force and loads the lower back.
- Treat every rep the same — a repeatable setup and bar path is what lets you add weight safely over time.
- Control the lowering phase — a 2–3 second descent builds more than dropping the weight.
Common mistakes
- Letting the knees cave inward as you push out of the bottom.
- Loading the bar heavier than your form allows and turning strict reps into a whole-body heave.
- Chasing weight jumps before the current load feels solid on every rep.
