The horse squat is a lower body exercise characterized by a wide stance and externally rotated feet, primarily targeting the inner thigh muscles, glutes, and quadriceps.

How to Horse Squat?

The horse squat, often interchangeably referred to as the sumo squat or plie squat, is a powerful lower body exercise characterized by a wide stance and externally rotated feet, primarily targeting the inner thigh muscles (adductors) in conjunction with the glutes and quadriceps.

What is the Horse Squat?

The horse squat is a variation of the traditional squat that emphasizes a wider stance and outward rotation of the feet and knees. This unique positioning shifts the primary muscular emphasis from the quadriceps (as in a narrow-stance squat) to the adductor group (inner thighs) and gluteal muscles, while still engaging the entire lower body and core. It mimics the stance of a horse rider, hence the name, promoting significant hip mobility and strength through a different plane of motion compared to conventional squats.

Muscles Worked

The horse squat is a compound exercise that engages multiple muscle groups simultaneously, with particular emphasis on:

  • Adductors (Inner Thighs): Primarily the adductor magnus, longus, and brevis, which are heavily recruited to stabilize the wide stance and contribute to the hip extension phase.
  • Gluteal Muscles: Gluteus maximus, medius, and minimus, responsible for hip extension and external rotation, especially as you drive up from the bottom of the squat.
  • Quadriceps: Vastus lateralis, medialis, intermedius, and rectus femoris, which are still active in knee extension, though less dominant than in a narrow-stance squat.
  • Hamstrings: Biceps femoris, semitendinosus, and semimembranosus, acting as synergists in hip extension.
  • Core Stabilizers: Transverse abdominis, obliques, and erector spinae, crucial for maintaining an upright torso and protecting the spine throughout the movement.

Key Benefits of the Horse Squat

Incorporating the horse squat into your routine offers several distinct advantages:

  • Enhanced Inner Thigh Strength and Development: It's one of the most effective exercises for directly targeting and strengthening the adductor muscles, which are often underdeveloped.
  • Improved Hip Mobility and Flexibility: The wide, externally rotated stance actively stretches the adductors and improves the range of motion in the hip joint.
  • Increased Glute Activation: The wider stance and external rotation can lead to greater engagement of the gluteal muscles, particularly at the bottom of the movement.
  • Better Core Stability: Maintaining an upright posture with a wide base demands significant core engagement, contributing to overall trunk stability.
  • Functional Strength: Strengthens muscles used in activities requiring a wide base, lateral movement, or strong hip abduction/adduction, such as martial arts, dancing, and various sports.
  • Reduced Knee Stress: For some individuals, the wider stance can reduce direct stress on the patellofemoral joint compared to narrow-stance squats.

Step-by-Step Guide to Performing the Horse Squat

Proper form is crucial for maximizing benefits and preventing injury. Follow these steps carefully:

  1. Starting Position:

    • Stand with your feet significantly wider than shoulder-width apart, typically 1.5 to 2 times shoulder-width.
    • Point your toes outward at an angle of approximately 45-60 degrees. Find an angle that feels comfortable and allows your knees to track over your toes.
    • Keep your chest up, shoulders back and down, and engage your core by bracing your abdominal muscles. You can hold a dumbbell or kettlebell in front of your chest (goblet style) for added resistance and to help balance.
  2. Descending Phase (The "Squat"):

    • Initiate the movement by pushing your hips back and simultaneously bending your knees.
    • Crucially, allow your knees to track directly over your toes. Do not let them cave inward. Actively push your knees outward throughout the descent.
    • Maintain a tall, upright torso. Avoid rounding your back or leaning excessively forward.
    • Descend until your thighs are parallel to the floor, or as deep as your hip mobility allows while maintaining proper form and keeping your heels on the ground.
  3. Ascending Phase (The "Stand"):

    • Drive through your heels and midfoot, pushing the floor away from you.
    • Squeeze your glutes and inner thighs as you extend your hips and knees to return to the starting position.
    • Maintain core engagement throughout the ascent.
    • Avoid locking out your knees forcefully at the top; keep a slight bend.
  4. Breathing:

    • Inhale as you descend.
    • Exhale powerfully as you ascend.

Key Cues for Optimal Form:

  • "Knees Out": Consciously push your knees outwards to align with your toes throughout the movement.
  • "Tall Chest": Keep your sternum lifted and shoulders retracted.
  • "Brace Your Core": Imagine preparing for a punch to maintain spinal stability.
  • "Squeeze Inner Thighs": Actively engage your adductors on the way up.

Common Mistakes to Avoid

  • Knees Caving In (Valgus Collapse): This is the most common and dangerous mistake. It puts excessive stress on the knee joint. Actively push your knees out.
  • Rounding the Back: Leads to spinal compression and potential injury. Maintain a neutral spine and upright chest.
  • Lifting Heels: Indicates a lack of ankle mobility or attempting to go too deep. Keep your entire foot planted.
  • Insufficient Depth: Not going deep enough limits the range of motion and the full benefits for the glutes and adductors.
  • Not Engaging Adductors: Simply going through the motion without consciously activating the inner thighs reduces the exercise's effectiveness.

Variations and Progression

Once you've mastered the bodyweight horse squat, consider these progressions:

  • Goblet Horse Squat: Hold a kettlebell or dumbbell vertically against your chest. This helps with balance and adds central load.
  • Dumbbell Horse Squat: Hold a dumbbell with both hands, letting it hang between your legs.
  • Barbell Horse Squat: Place a barbell across your upper back (like a traditional back squat) or front rack. This is a more advanced variation requiring significant core strength and stability.
  • Horse Squat Pulses: At the bottom of the squat, perform small, controlled up-and-down movements for added intensity.
  • Elevated Heel Horse Squat: Placing small plates under your heels can help individuals with limited ankle mobility achieve greater depth, though it slightly reduces adductor stretch.

Who Can Benefit?

The horse squat is a versatile exercise beneficial for:

  • Athletes: Especially those in martial arts, dance, gymnastics, or sports requiring strong lateral movement and hip mobility.
  • Weightlifters and Bodybuilders: To target the inner thighs for comprehensive leg development and improve squat depth in other variations.
  • Individuals Seeking Hip Mobility Improvement: The wide stance actively stretches the adductors and hip flexors.
  • Anyone Looking for Glute and Inner Thigh Development: It's an excellent way to strengthen often-neglected muscle groups.
  • Those with Knee Discomfort: For some, the wider stance can be more comfortable than narrow squats, but always consult a professional if experiencing pain.

Integrating the Horse Squat into Your Routine

The horse squat can be incorporated into various workout splits:

  • Warm-up: A few sets of bodyweight horse squats can be an excellent dynamic warm-up for leg day, preparing the hips and adductors.
  • Leg Day: Perform 3-4 sets of 8-15 repetitions as a primary lower body exercise or as an accessory movement after compound lifts.
  • Full-Body Workouts: Include 2-3 sets as part of your lower body component.
  • Rep Range: For strength, aim for lower reps (e.g., 5-8 with heavier weight). For hypertrophy (muscle growth) and endurance, aim for higher reps (e.g., 10-20 with moderate weight).

Safety Considerations

  • Listen to Your Body: Never push through sharp pain. Discomfort is normal, but pain is a warning sign.
  • Warm-up Thoroughly: Prepare your muscles and joints with dynamic stretches and light cardio before attempting the horse squat.
  • Start with Bodyweight: Master the form without added weight before progressing to dumbbells or barbells.
  • Footwear: Wear flat, stable shoes that allow your feet to spread and grip the floor.
  • Consult a Professional: If you have pre-existing knee, hip, or back conditions, consult a physical therapist or certified personal trainer before adding this exercise to your routine.
