Single-Leg Squat with a Bench: Guide, Benefits, and Progression

How to do one leg squat with a bench?

The single-leg squat with a bench is a highly effective unilateral exercise that enhances lower body strength, balance, and proprioception by using a bench as a depth marker and safety net, making it an excellent progression towards unassisted pistol squats.

Understanding the Exercise: What is a Single-Leg Squat with a Bench?

The single-leg squat with a bench, often referred to as a "box pistol squat" or "bench pistol squat," is a foundational unilateral lower body exercise. It involves performing a squat on one leg while the other leg is extended forward, and the hips descend until they lightly touch or tap a bench positioned behind you. This exercise is distinct from a Bulgarian split squat, where the non-working leg is elevated behind you on a bench. In the context of a single-leg squat with a bench, the bench serves as a crucial point of reference for depth, offering a controlled range of motion and a psychological safety net, which is particularly beneficial for those developing the strength and balance required for a full pistol squat.

Muscles Engaged

This exercise comprehensively targets the muscles of the lower body and core, emphasizing unilateral strength and stability.

• Primary Movers:
  • Quadriceps: (Rectus femoris, vastus lateralis, vastus medialis, vastus intermedius) – responsible for knee extension.
  • Gluteus Maximus: – responsible for hip extension.
  • Hamstrings: (Biceps femoris, semitendinosus, semimembranosus) – act as synergists and stabilizers, particularly at the bottom of the squat.
• Stabilizers:
  • Gluteus Medius and Minimus: – crucial for hip abduction and stabilization, preventing the knee from caving inward.
  • Adductor Magnus: – assists in hip extension and stabilization.
  • Core Muscles: (Rectus abdominis, obliques, erector spinae, transverse abdominis) – maintain spinal stability and transfer force.
  • Ankle Stabilizers: (Tibialis anterior, gastrocnemius, soleus) – maintain balance throughout the movement.

Benefits of Incorporating This Exercise

Adding the single-leg squat with a bench to your routine offers several significant advantages for fitness enthusiasts and athletes:

• Enhanced Unilateral Strength: It builds strength equally in each leg, addressing muscular imbalances that can arise from bilateral (two-legged) exercises.
• Improved Balance and Stability: The single-leg stance demands significant activation of stabilizing muscles around the hip, knee, and ankle, leading to better balance and proprioception.
• Increased Functional Strength: Mimics real-life movements like walking, running, and climbing stairs, translating to better performance in daily activities and sports.
• Reduced Risk of Injury: By strengthening stabilizing muscles and improving movement control, it can help prevent common lower body injuries.
• Progression for Advanced Skills: Serves as an excellent stepping stone towards more challenging unilateral movements like the full pistol squat.
• Low Impact on Spine: Compared to bilateral barbell squats, it places less direct axial load on the spine, potentially making it suitable for individuals with certain back considerations (though always consult a professional).

Step-by-Step Guide: How to Perform the Single-Leg Squat with a Bench

Proper form is paramount to maximize benefits and minimize injury risk.

1. Set Up:

   • Choose your bench height: Start with a bench that allows you to comfortably squat to it with control. A higher bench makes the exercise easier; a lower bench increases the challenge.
   • Standing position: Stand approximately 6-12 inches in front of the bench, facing away from it. Ensure there's enough clear space in front of you.
   • Initial stance: Stand tall with your feet hip-width apart.
   • Engage core: Brace your abdominal muscles as if preparing for a punch. This helps stabilize your spine.

2. Lift One Leg:

   • Shift your weight onto one foot (e.g., your right foot).
   • Slowly lift your non-working leg (e.g., your left leg) straight out in front of you. Keep it as straight as possible, elevated off the floor. You can extend your arms forward for counterbalance.

3. Initiate the Descent:

   • Control the movement: Begin to slowly lower your body by bending your working knee and pushing your hips back, as if you're going to sit down onto the bench.
   • Maintain balance: Keep your chest upright, gaze forward, and your core tight throughout the descent.
   • Knee alignment: Ensure your working knee tracks in line with your toes, avoiding excessive inward or outward movement.
   • Non-working leg: Continue to keep your non-working leg extended forward, preventing it from touching the ground.

4. Tap the Bench:

   • Continue descending until your glutes lightly tap the surface of the bench. Avoid crashing down onto the bench; the tap should be controlled and brief.

5. Ascend:

   • Drive through the heel: Immediately, drive through the heel and midfoot of your working foot to push yourself back up to the starting standing position.
   • Extend fully: Fully extend your working hip and knee at the top, but avoid locking out the knee forcefully.
   • Maintain balance: Keep your non-working leg elevated throughout the entire movement.

6. Repeat:

   • Perform your desired number of repetitions on one leg before switching to the other.

Common Mistakes to Avoid

• Losing Balance: This is common. Focus on a fixed point, engage your core, and ensure slow, controlled movement.
• Knee Caving In (Valgus Collapse): This indicates weak hip abductors (glute medius). Actively push your knee slightly outwards to align with your toes.
• Rounding the Back: Losing core tension can lead to a rounded lower back. Keep your chest up and core braced.
• Crashing Onto the Bench: The bench is a depth guide, not a place to rest. The movement should be controlled down to a light tap.
• Not Going Deep Enough (Too High a Bench): While a higher bench is a good starting point, progress to a lower bench as strength improves to gain the full range of motion benefits.
• Letting the Non-Working Foot Touch Down: This reduces the unilateral challenge. Keep the foot elevated.

Progression and Regression Strategies

The single-leg squat with a bench is highly adaptable to different fitness levels.

• Regression (Making it Easier):

  • Use a higher bench: Reduces the range of motion required.
  • Hold onto support: Use a sturdy pole, doorframe, or TRX strap for balance assistance.
  • Reduce range of motion: Only descend partway, not all the way to the bench.
  • Eccentric focus: Focus only on the lowering (eccentric) phase on one leg, then use both legs to stand back up.
  • Chair assistance: Use a chair with armrests to push off slightly.

• Progression (Making it Harder):

  • Use a lower bench: Increases the range of motion and challenge.
  • Decrease bench height over time: Gradually work towards a full pistol squat without a bench.
  • Add external weight: Hold a dumbbell or kettlebell in a goblet position (at your chest) or in each hand.
  • Increase tempo control: Slow down the eccentric (lowering) phase to 3-5 seconds.
  • Increase volume: More sets or repetitions.
  • Perform on an unstable surface: (Advanced) Only after mastering on a stable surface, try a slight wobble board.

Integrating into Your Training Program

The single-leg squat with a bench can be incorporated into various training routines:

• Warm-up: As part of a dynamic warm-up to activate the lower body and improve mobility.
• Strength Training: As a primary lower body exercise on a leg day or full-body workout. Aim for 3-4 sets of 6-12 repetitions per leg, depending on your goals (strength vs. endurance).
• Balance and Stability Work: Include it in routines focused on improving proprioception and functional movement.
• Rehabilitation: Under the guidance of a physical therapist, it can be used to rebuild strength and control after lower limb injuries.

When to Seek Professional Guidance

While the single-leg squat with a bench is a fantastic exercise, it's crucial to listen to your body. If you experience any sharp pain, discomfort, or have pre-existing knee, hip, or ankle conditions, consult with a qualified healthcare professional (e.g., a physical therapist, orthopedic doctor) or a certified personal trainer. They can provide personalized advice, modify the exercise, or suggest alternative movements to ensure your safety and optimize your results.
