Single Leg Box Squat (pistol)
The Single Leg Box Squat (pistol) primarily works the Gluteus Maximus, Rectus Femoris, with secondary activation of the Adductor Magnus, Gluteus Maximus, Rectus Femoris, Soleus and stabilizer support from the Biceps Femoris (Long Head), Erector Spinae, External Obliques, Gastrocnemius (Medial), Gluteus Medius, Gluteus Minimus, Quadratus Lumborum, Rectus Abdominis. It is a bodyweight compound exercise at advanced difficulty.
The Single Leg Box Squat (pistol) is a advanced compound exercise requiring no equipment, 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.
A bodyweight compound push exercise targeting the Gluteus Maximus and Rectus Femoris.

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 Biceps Femoris (Long Head), Erector Spinae, External Obliques, and 5 other muscles 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 Biceps Femoris (Long Head) (hamstrings)
- Stabilizer Muscle Erector Spinae (back)
- Stabilizer Muscle External Obliques (core)
- Stabilizer Muscle Gastrocnemius (Medial) (calves)
- Stabilizer Muscle Gluteus Medius (glutes)
- Stabilizer Muscle Gluteus Minimus (glutes)
- Stabilizer Muscle Quadratus Lumborum (core)
- Stabilizer Muscle Rectus Abdominis (core)
How to Perform
Preparation
- Stand in front of adjustable height bench or box.
- Extend arms out in front of body.
- Balance on one leg with opposite leg extended forward off of ground.
Execution
- Squat down while keeping leg elevated off of floor.
- Keep back straight and supporting knee pointed same direction as foot supporting.
- Once bottocks makes contact with bench or box, raise body back up to original position until knee and hip of supporting leg is straight.
- Repeat and continue with opposite leg.
Comments
- Range of motion will be improved with greater leg strength.
- Supporting knee should point same direction as foot throughout movement.
- Weighted versions of this exercise would normally be considered auxiliary in context of other basic exercises (ie: Barbell Squat, Sled Leg Press).
- However, in the context of 'body weight' only program, this exercise can be considered basic.
- Also known as Bench Pistol Squat or Single Leg Bench 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. This is an advanced exercise — experienced lifters can push intensity higher and use more varied rep schemes.
| 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.
