If you’re ready to take your training to the next level, let’s dive into everything that makes this exercise so special!

What is the Bulgarian Split Squat?

The Bulgarian split squat targets the lower body by isolating one leg at a time. With one foot elevated behind you on a bench, the other leg performs the squat.

This setup requires the working leg to stabilize and power the movement, leading to significant improvements in strength, balance, and flexibility.

Unlike traditional squats, this exercise provides a deep stretch to the hip flexors and enhances overall mobility.

While exercises like the trap bar deadlift and conventional back squats are staples in my strength training routine, the Bulgarian split squat offers unique advantages:

Unilateral Strength: It isolates one leg at a time, helping to correct imbalances and promote symmetrical strength.
Core Engagement: The exercise requires significant core stability, engaging the abdominal muscles to maintain balance.
Hip Flexor Mobility: The position allows for a deeper stretch in the hip flexors, which is not achievable with traditional squats.
Functional Movement: The Bulgarian split squat mimics everyday movements and athletic activities, making it highly functional.

How to Do a Bulgarian Split Squat

Performing the Bulgarian split squat with correct form is essential to maximize benefits and prevent injury. Here’s how to do it right:

Setup: Stand a few feet in front of a bench or raised surface. Extend one leg behind you and rest the top of your foot on the bench.
Foot Placement: Ensure your front foot is far enough forward so that when you descend, your knee doesn’t extend past your toes.
Descent: Slowly lower your hips towards the ground, bending the front knee. The back knee should move straight down, lightly touching the ground or hovering above it. Keep your torso upright.
Ascent: Push through your front heel to return to the starting position, engaging your glutes, quads, and hamstrings.
Repetition: Complete the desired number of reps before switching legs. Focus on controlled movements for maximum muscle engagement.

Tips for Perfecting Your Form

Torso Alignment: Maintain a slight forward lean to keep the focus on the front leg.
Breathing: Inhale as you lower yourself and exhale as you rise.
Knee Position: Keep the front knee in line with your toes to avoid stress on the knee joint.
Foot Placement: Adjust your front foot’s distance to find the most balanced position.

Common Mistakes to Avoid

Leaning Too Much Forward or Backward: This shifts the focus away from the legs and can strain the lower back.
Neglecting the Back Leg: The back leg should provide balance, not push the body upwards.
Rushing the Movement: Slow, controlled movements ensure proper form and muscle activation.

Muscles Worked

The Bulgarian split squat offers a more targeted approach to unilateral leg strength compared to traditional squats and deadlifts. This focus on one leg at a time is particularly beneficial for athletes needing to correct muscle imbalances or enhance single-leg power, which is crucial in sports like basketball, soccer, and track and field.

Primary Muscles Engaged

The Bulgarian split squat is excellent for developing lower body strength, primarily targeting:

Quadriceps: The quads in the front leg bear most of the load, especially during the ascent.
Glutes: The gluteus maximus is engaged to stabilize the hip and power the movement.
Hamstrings: These muscles work together with the quads and glutes, particularly during the descent.

Secondary Muscles and Stabilizers

Beyond the primary muscles, the Bulgarian split squat also activates several secondary muscles:

Hip Flexors: The rear leg’s extended position stretches and strengthens the hip flexors, improving flexibility and mobility.
Core: Maintaining torso stability requires significant core engagement, including the rectus abdominis, obliques, and transverse abdominis.
Calves: The calf muscles help stabilize the ankle and maintain balance throughout the movement.

Bulgarian Split Squat Benefits

The Bulgarian split squat is more than just a leg exercise; it’s a movement that can transform your athletic performance, improve your strength, and enhance your mobility.

Whether you’re an elite athlete or someone looking to improve your fitness, the Bulgarian split squat is a powerful single-leg exercise that targets the quads, glutes, and hamstrings while also improving balance and stability.

Remember to start with proper form, gradually increase intensity, and explore the various variations to keep challenging your body.

As you progress, you’ll likely find that the Bulgarian split squat not only strengthens your legs but also improves your overall functional fitness, making it easier to perform everyday activities and excel in sports.

With consistency and dedication, you’ll experience firsthand why this exercise has become my all-time favorite and why it can be a game-changer for you, too.

Single-Leg Strength and Stability

Unilateral exercises like the Bulgarian split squat are crucial for developing strength and stability in each leg independently. This is particularly important for athletes, as many sports movements involve one leg at a time—sprinting, jumping, and changing directions are all examples.

Correcting Imbalances: Working one leg at a time helps identify and correct muscle imbalances, leading to improved performance and reduced injury risk.
Enhancing Performance: Stronger, more stable legs lead to better performance in activities requiring speed, power, and agility.

Balance and Coordination

The Bulgarian split squat challenges your balance and coordination, making it an excellent exercise for athletes looking to enhance these critical aspects of performance. As you balance on one leg, your body must engage stabilizer muscles to maintain control, leading to:

Better Proprioception: Your body becomes more aware of its position in space, improving overall athletic ability.
Injury Prevention: Enhanced balance reduces the likelihood of falls and injuries, particularly in dynamic sports environments.

Hip Flexor Mobility

One of the unique benefits of the Bulgarian split squat is its ability to stretch and strengthen the hip flexors. Tight hip flexors are a common issue, especially for athletes and those who spend a lot of time sitting. This exercise promotes:

Greater Flexibility: The deep stretch on the back leg improves hip flexor flexibility, which is crucial for a full range of motion in athletic movements.
Better Posture: Improved hip flexor mobility can alleviate lower back pain and enhance posture, both of which are vital for optimal performance.

Versatility and Progression

The Bulgarian split squat is not only effective but also incredibly versatile. Whether you’re a beginner or an advanced athlete, there are variations and progressions that can match your fitness level and goals.

This adaptability ensures the exercise remains challenging and effective as you continue to progress in your training.

Bulgarian Split Squat Variations

I’ve done many Bulgarian split squat variations over the years, and they all produce different benefits and effects. Sometimes, I will also elevate my front foot to increase the hip mobility of the exercise and work the muscles through a greater range of motion.

Dumbbell Bulgarian Split Squat

The dumbbell Bulgarian split squat is a popular variation that adds an extra challenge by incorporating weights. Holding a dumbbell in each hand increases the load on the working leg, intensifying the exercise.

Benefits: This variation allows for greater progression in strength training. The added weight challenges the muscles more than the bodyweight version.
Form Tips: Maintain proper alignment and avoid letting the weights pull your torso forward. Focus on slow, controlled movements to maximize muscle engagement.

Barbell Bulgarian Split Squat

The barbell Bulgarian split squat takes the exercise to another level by adding significant weight, making it more suitable for advanced lifters.

Benefits: This variation is excellent for building maximal strength and power in the lower body. The barbell allows you to add more weight than with dumbbells.
Form Tips: Position the barbell across your upper back, as in a back squat, and ensure your core is engaged to prevent leaning forward. This variation demands excellent balance and stability.

Smith Machine Bulgarian Split Squat

For those who struggle with balance, the Smith machine Bulgarian split squat offers a safer alternative. The guided movement of the Smith machine allows you to focus more on muscle engagement without worrying about balance.

Benefits: It’s ideal for those who are new to the exercise or those recovering from an injury. The machine provides stability, allowing for a controlled range of motion.
Form Tips: Ensure your feet are correctly positioned to prevent the bar from moving in an unnatural path. Keep your torso upright and engage your core throughout the movement.

Resistance Band Bulgarian Split Squat

The resistance band Bulgarian split squat adds an extra challenge by using a resistance band anchored to a pole behind you. This setup increases the difficulty as you rise from the squat, enhancing muscle engagement and stability.

Benefits: This variation is excellent for improving stability and power. The resistance band increases tension during the ascent, making your glutes, quads, and hamstrings work harder. It’s also a great way to engage your core more effectively and add progressive overload without needing additional weights.

Form Tips: Position the resistance band at hip height and step forward to keep it taut. Focus on maintaining balance by keeping your torso upright and engaging your core. Ensure your front knee stays aligned with your toes, and control your movements to maximize the benefits of the added resistance.

Advanced Unilateral Training and Progressions

As you become more proficient in the Bulgarian split squat, you can explore more advanced unilateral training techniques. These might include:

Single-Arm Dumbbell Variation: Holding a dumbbell in only one hand increases the challenge to your core and balance.
Plyometric Bulgarian Split Squat: Adding a jump at the top of the movement transforms the exercise into a powerful plyometric drill, boosting explosive strength and power.
Tempo Variations: Slowing down the eccentric (lowering) phase or adding a pause at the bottom can significantly increase time under tension, enhancing muscle growth and endurance.

Form & Safety Tips

Even with its numerous benefits, the Bulgarian split squat can be ineffective or even dangerous if not performed correctly. Here are some common mistakes and how to avoid them:

Leaning Too Far Forward or Backward: This mistake shifts the focus away from the working leg and places unnecessary strain on the lower back. To correct this, maintain a slight forward lean, keeping your torso upright and core engaged.
Incorrect Foot Placement: Placing your front foot too close to the bench or too far away can compromise the exercise’s effectiveness. Ideally, your front knee should align over your ankle when in the bottom position. Adjust your foot placement until you find the right balance.
Letting the Knee Cave Inward: This can put undue stress on the knee joint and lead to injury. Focus on keeping your knee in line with your toes throughout the movement.
Rushing the Movement: Speeding through the reps can lead to poor form and reduced muscle activation. Slow down and focus on a controlled descent and ascent, maximizing time under tension.
Neglecting the Back Leg: While the back leg should not be doing most of the work, it’s still essential to keep it engaged for balance. The back leg should provide just enough support without pushing the body upward.

How to Correct These Mistakes

Use a Mirror: Training in front of a mirror can help you monitor your form and make adjustments in real-time.
Start with Bodyweight: Before adding weight, master the bodyweight Bulgarian split squat to ensure proper form.
Get Feedback: If possible, have a coach or workout partner observe your form and provide feedback.

Sets, Reps, and Progressions

As with any exercise, progression is key to continued improvement. Here’s how to progress with the Bulgarian split squat:

Increase Weight: Gradually add weight as you become stronger. Start with bodyweight, then progress to dumbbells, kettlebells, and eventually barbells.
Change Tempo: Slowing down the movement, especially during the lowering phase, can increase the difficulty and stimulate muscle growth.
Add Plyometric Variations: Once you’ve mastered the basic movement, incorporate plyometric Bulgarian split squats to develop explosive power.
Try Unstable Surfaces: Perform the exercise on a slightly unstable surface, like a soft mat or balance pad, to further challenge your balance and stability.
