Muscles Worked: A Lower Body Powerhouse Bulgarian Split Squat
The Bulgarian Split Squat is a compound exercise, meaning it engages multiple muscle groups simultaneously. This makes it incredibly efficient for building strength and improving overall fitness. Here’s a breakdown of the primary muscles targeted:

- Quadriceps: These are the large muscles on the front of your thighs and are the prime movers in the BSS. They’re responsible for extending your knee during the squatting motion. The quadriceps in your front leg bear the brunt of the work.
- Glutes (Gluteus Maximus, Medius, and Minimus): The glutes, especially the gluteus maximus, play a significant role in hip extension and stabilization. They work hard to power you back up from the bottom of the squat. The gluteus medius also contributes to hip stability, preventing your knee from caving inward.
- Hamstrings: Located on the back of your thighs, the hamstrings assist in hip extension and knee flexion. They work in conjunction with the glutes to provide power and stability during the exercise.
- Calves (Gastrocnemius and Soleus): These muscles in your lower leg assist in plantar flexion (pointing your toes) and contribute to overall stability.
- Core (Abdominals, Obliques, and Lower Back): Your core muscles are crucial for maintaining balance and stability throughout the movement. They prevent excessive rotation and extension of your spine, keeping you upright and controlled.
- Adductors (Inner Thighs): These muscles assist in hip adduction (bringing your leg towards the midline of your body) and help stabilize the knee joint.
Beyond the Prime Movers: The BSS also engages smaller stabilizer muscles throughout your lower body and core, contributing to improved balance, coordination, and proprioception (your body’s awareness of its position in space).
How to Do a Bulgarian Split Squat: Step-by-Step Guide
Proper form is essential to maximize the benefits of the BSS and minimize the risk of injury. Here’s a detailed breakdown of how to perform the exercise correctly:

- Setup:
- Find a stable elevated surface, such as a bench, box, or sturdy chair. The height should be approximately knee-height or slightly lower.
- Stand facing away from the elevated surface, about two to three feet in front of it.
- Place one foot behind you on the elevated surface. The top of your foot or your toes can be placed on the surface, depending on your preference and flexibility. Experiment to find what feels most comfortable.
- Position your front foot far enough forward so that when you descend into the squat, your front knee doesn’t extend past your toes. You might need to adjust your stance a few times to find the perfect position.
- Starting Position:
- Stand tall with your chest up, shoulders back, and core engaged.
- Distribute your weight evenly through your front foot.
- Your back leg should be relaxed on the elevated surface.
- Descending:
- Inhale and slowly lower your body by bending your front knee and hip.
- Keep your torso upright and your core engaged.
- Lower yourself until your front thigh is roughly parallel to the ground (or as low as your flexibility allows while maintaining good form). Your back knee should be hovering just above the ground.
- Ensure that your front knee tracks in line with your toes and doesn’t cave inward or outward.
- Ascending:
- Exhale and push through your front heel to return to the starting position.
- Focus on engaging your glutes and quadriceps in your front leg.
- Maintain your balance and control throughout the upward movement.
- Repetitions and Sets:
- Perform the desired number of repetitions on one leg, then switch to the other leg.
- Aim for 2-3 sets of 8-12 repetitions per leg for strength training, or adjust the rep range based on your goals.
Bulgarian Split Squat – Key Form Points to Remember
- Upright Torso: Maintain a straight back and avoid rounding your shoulders or leaning forward excessively.
- Knee Alignment: Ensure your front knee tracks in line with your toes. Avoid letting it cave inward (valgus) or outward (varus).
- Depth: Aim for your front thigh to be parallel to the ground, but prioritize good form over depth. Don’t force yourself to go too low if you can’t maintain proper alignment.
- Core Engagement: Keep your core muscles tight throughout the exercise to stabilize your spine and prevent excessive movement.
- Controlled Movement: Perform the exercise with slow, controlled movements. Avoid bouncing or rushing through the repetitions.
Benefits of the Bulgarian Split Squat: Unleashing Your Potential

- Increased Lower Body Strength: The BSS effectively strengthens the quadriceps, glutes, hamstrings, and calves, leading to improved overall lower body power and performance.
- Improved Muscle Imbalances: By working each leg independently, the BSS helps identify and correct muscle imbalances between your left and right sides. This can improve your overall biomechanics and reduce the risk of injury.
- Enhanced Balance and Stability: The BSS challenges your balance and stability, forcing you to engage your core and stabilizer muscles to maintain control. This translates to improved balance in everyday activities and sports.
- Improved Core Strength: The BSS requires significant core engagement to maintain stability and prevent excessive spinal movement. This can lead to improved core strength and stability, which is essential for overall health and athletic performance.
- Increased Hip Mobility: The BSS can improve hip mobility by stretching the hip flexors and allowing for a greater range of motion in the hip joint.
- Functional Strength: The BSS mimics movements that occur in everyday life and sports, making it a highly functional exercise. It improves your ability to perform tasks such as walking, running, jumping, and climbing stairs with greater ease and efficiency.
- Reduced Spinal Loading: Compared to traditional back squats, the BSS places less compressive force on the spine, making it a suitable option for individuals with lower back pain or those who want to minimize spinal stress.
- Enhanced Athletic Performance: The BSS can improve athletic performance by increasing lower body power, balance, stability, and core strength. This can translate to improved speed, agility, and jumping ability in various sports.
- Variety and Challenge: The BSS adds variety and challenge to your training routine, preventing plateaus and keeping your workouts engaging.
Variations of the Bulgarian Split Squat: Adapting to Your Needs and Goals
The BSS can be modified and progressed to suit your individual needs, fitness level, and training goals. Here are some popular variations:

- Bodyweight Bulgarian Split Squat: This is the foundational variation and is perfect for beginners. Focus on mastering the proper form before adding weight.
- Dumbbell Bulgarian Split Squat: Hold a dumbbell in each hand while performing the BSS to increase the resistance and challenge your muscles further.
- Goblet Bulgarian Split Squat: Hold a single dumbbell or kettlebell close to your chest while performing the BSS. This variation challenges your core stability and promotes an upright torso.
- Barbell Bulgarian Split Squat: This is a more advanced variation that involves performing the BSS with a barbell across your upper back, similar to a back squat. This variation requires a higher level of strength and stability.
- Deficit Bulgarian Split Squat: Elevate your front foot on a small platform or step to increase the range of motion and challenge your muscles even more.
- Jump Bulgarian Split Squat: Explosively jump upwards at the top of the squat, adding a plyometric element to the exercise. This variation is excellent for developing power and explosiveness.
