Barbell Single Leg Split Squat
The Barbell Single Leg Split Squat primarily works the Gluteus Maximus, Rectus Femoris, with secondary activation of the Adductor Magnus, Gluteus Maximus, Rectus Femoris, Soleus and stabilizer support from the Erector Spinae, Gluteus Medius, Gluteus Minimus. It is a barbell compound exercise at intermediate difficulty.
The Barbell Single Leg Split Squat is a intermediate compound exercise performed with barbell, following a squat movement pattern. It primarily targets the Gluteus Maximus, Rectus Femoris, with secondary engagement of the Adductor Magnus, Gluteus Maximus, Rectus Femoris, Soleus. As a unilateral push, each side is trained independently for balanced development.

Muscles Worked
The Gluteus Maximus, and Rectus Femoris are the primary movers, collectively driving the movement and absorbing the greatest share of the load. The Adductor Magnus, Gluteus Maximus, Rectus Femoris, and Soleus act as secondary movers, assisting the primary muscles and contributing meaningfully to the overall output. The Erector Spinae, Gluteus Medius, Gluteus Minimus act as stabilizers, maintaining joint position and postural alignment throughout the movement.
Primary Muscles
- Primary Muscle Gluteus Maximus (glutes)
- Primary Muscle Rectus Femoris (quadriceps)
Secondary Muscles
- Secondary Muscle Adductor Magnus (adductors)
- Secondary Muscle Gluteus Maximus (glutes)
- Secondary Muscle Rectus Femoris (quadriceps)
- Secondary Muscle Soleus (calves)
Stabilizer Muscles
- Stabilizer Muscle Erector Spinae (back)
- Stabilizer Muscle Gluteus Medius (glutes)
- Stabilizer Muscle Gluteus Minimus (glutes)
How to Perform
Preparation
- Stand facing away from bench.
- Position bar on back of shoulders and grasp barbell to sides.
- Extend leg back and place top of foot on bench.
Execution
- Squat down by flexing knee and hip of front leg until knee of rear leg is almost in contact with floor.
- Return to original standing position by extending hip and knee of forward leg.
- Repeat.
- Continue with opposite leg.
Comments
- Keep majority of bodyweight on forward leg, using rear leg primarily for balance.
- Keep torso somewhat upright during squat;flexible hip flexorsare important.
- Forward knee should point same direction as foot throughout the movement.
- See side view.
- Also seeBulgarian Squat.
Tips & Common Mistakes
- Keep your chest up and spine neutral throughout — avoid rounding your lower back.
- Push your knees out in line with your toes as you descend.
- Aim for at least parallel depth — cutting squats short reduces muscle activation.
Programming Suggestions
Adapt your sets and reps to your training goal.
| Strength | 3–5 sets × 3–6 reps at 80–90% 1RM with 2–4 minutes rest. |
|---|---|
| Hypertrophy | 3–5 sets × 6–12 reps at 65–80% 1RM with 60–120 seconds rest. |
| Endurance | 2–4 sets × 15–20 reps at 50–65% 1RM with 30–60 seconds rest. |
Alternative Exercises
These exercises target the same primary muscles (Gluteus Maximus, Rectus Femoris) and can be substituted based on your equipment or variation preferences.
