Bulgarian split squat: the unilateral leg exercise with the greatest impact on glutes and quadriceps

The Bulgarian squat is one of the most complete unilateral exercises to train the lower body. Also known as the Bulgarian Split Squat or Bulgarian lunge, it allows working each leg separately, improving stability and strengthening the glutes, quadriceps, and hamstrings with a movement that is very demanding technically.

Unlike a traditional squat, in the Bulgarian squat one leg is kept forward and bears most of the effort, while the rear leg is elevated on a bench. This position forces the body to better control balance, stabilize the hip, and maintain good alignment throughout the entire movement.

That is why it is a widely used exercise in strength, hypertrophy, functional training, and physical preparation routines. You don’t need to be advanced to include it, but it is advisable to learn the technique well before adding weight. Properly performed, the Bulgarian squat can be done in the gym, at home, with body weight, dumbbells, or a barbell.

In this article, we look at which muscles the Bulgarian squat works, how to do it correctly, how to modify the position to emphasize the glute or quadriceps, what mistakes to avoid, and how to progress with the right equipment.

Bulgarian squat muscles: which areas does it work?

The Bulgarian squat primarily works the muscles of the forward leg. The rear leg serves as support but should not be the one doing the main effort. This is one of the keys to the exercise: although both legs participate, the load should be felt mainly in the front leg.

• Quadriceps: are one of the most involved muscle groups. They participate especially during the ascent, when the knee extends to return to the starting position. If the front foot is placed slightly closer to the bench and the torso remains more upright, the work on the quadriceps is usually greater.
• Gluteus maximus: is another key player in the exercise. It activates intensely when the step is slightly longer and the hip has more range of motion. That is why many people use the Bulgarian squat as a main exercise within leg and lower body routines.
• Hamstrings: help control the hip and stabilize movement, especially during the lowering phase. They are not the dominant muscle but assist in making the execution firmer.
• Adductors and abductors: work to keep the knee aligned and prevent the leg from moving inward or outward. They are important for hip stability and for smooth movement.
• Core: the abdomen, lower back, and deep muscles help keep the torso stable. The Bulgarian squat is not a specific abdominal exercise, but it forces the core to work throughout the entire repetition.

That is why, when we talk about Bulgarian squat muscles, we are not only referring to the legs. Hip stabilizers, abdomen, and lower back also engage, making this exercise a very complete option to improve strength, balance, and body control.

Bulgarian squat for glutes or quadriceps: how to change the focus

One advantage of the Bulgarian squat is that you can slightly modify the position to emphasize either the glute or the quadriceps.

To focus more on the quadriceps, place the front foot a bit closer to the bench and keep the torso more upright. In this position, the knee moves forward more during the descent, and the quadriceps participate more intensely in leg extension.

To focus more on the glute, place the front foot slightly further forward and allow a slight forward lean of the torso. The back should remain stable without rounding. This position increases hip flexion and makes the glute more involved during the ascent.

The key is not to exaggerate either adjustment. If the step is too short, you may feel too much tension in the knee. If the step is too long, you may lose stability and reduce control of the movement.

Ideally, try several positions until you find a distance that allows you to descend safely, keep the knee aligned, and feel the effort in the front leg. A good Bulgarian squat should not feel like an uncomfortable or forced movement but rather a demanding yet controlled exercise.

How to do the Bulgarian squat correctly

The Bulgarian squat technique seems simple but requires more control than it appears. Before adding dumbbells or a barbell, it is advisable to master the movement with body weight.

The most common option is to use a stable weight bench to support the rear foot. A box or firm surface can also be used, but the support should not move or be too high. The height should allow you to rest your foot without straining the hip or losing stability.

Stand with your back to the bench and rest the instep or tip of the rear foot on the surface. The front leg should be positioned far enough forward to allow a comfortable descent without losing balance or straining the knee.

From that position, engage your core, keep your chest open, and look forward. Bend the front leg’s knee and lower in a controlled manner. Most of the weight should rest on the front leg, not on the back foot.

During the descent, the knee should follow the same line as the foot. Avoid letting it collapse inward, especially when fatigue sets in. Lower until the thigh is close to parallel to the ground or as far as your mobility allows while maintaining good posture.

To rise, push the ground with the front leg, mainly using the middle of the foot and the heel. Don’t bounce at the bottom or use momentum. A good Bulgarian split squat should feel stable, controlled, and clean throughout the entire range of motion.

How to know if you’re doing the Bulgarian Split Squat correctly

An easy way to know if you’re doing the Bulgarian Split Squat correctly is to notice where you feel the effort. The front leg should be the main focus. It’s normal to feel work in the quadriceps, glute, and hip stabilizers.

If you feel too much tension in the back leg, you may be putting too much weight on the bench. In that case, check the distance of the front foot and think about using the back leg only for support.

If you constantly lose balance, you may be using too much weight or haven’t yet found a comfortable position. Before adding weight, practice several sets with body weight until the movement is stable.

If you feel discomfort in the front knee, check the alignment. The knee should not collapse inward and the foot should remain firm throughout the repetition. Adjusting the step distance can also help.

The Bulgarian split squat doesn’t have to be done quickly. In fact, it’s usually more effective when the descent is controlled, there is a slight pause at the bottom, and the ascent is done without momentum. In this exercise, controlling the movement usually contributes more than increasing the load too soon.

Common mistakes in the Bulgarian split squat

One of the most common mistakes is starting with too much weight. The Bulgarian split squat requires stability, so adding weight before mastering the technique usually causes swaying, compensations, and incomplete ranges of motion.

Incomplete range of motion also greatly limits the exercise. You don’t need to go lower than your mobility allows, but it’s advisable to seek enough depth for the movement to make sense. Less weight and more control is usually better than heavy load with poor technique.

Finally, many people push with the back leg without realizing it. The elevated leg should help with balance, not do the main work. If you feel a lot of effort in the foot supported behind, check your position and reduce the load until you regain control.

Bulgarian split squat with dumbbells

The Bulgarian split squat with dumbbells is one of the most practical variants for most people. It allows progressive load addition, keeps the center of gravity relatively low, and does not require as much stability as the bar version.

To do it, hold a dumbbell in each hand at your sides. Keep your arms relaxed, grip firm, and avoid swinging the dumbbells during the repetition. The load should follow the body, not pull you forward or cause you to lose posture.

This variant fits very well both at home and in the gym. You can start with light dumbbells and gradually increase the weight as your technique improves. You can also use a single dumbbell in a goblet position, holding it in front of the chest, although this option usually limits the total load more.

The professional and home dumbbells are a good option to progress without needing a large setup. Combined with a stable bench, they allow working the Bulgarian split squat and many other leg, torso, and core exercises.

The Bulgarian split squat with dumbbells is usually the best intermediate option: more demanding than the bodyweight version but easier to control than the bar version. For this reason, it is a highly recommended variant for hypertrophy, general strength, and leg training with minimal equipment.

Bulgarian split squat with bar

The Bulgarian split squat with bar is a more advanced variant. It allows moving more load but also requires greater technical control. It is usually not the best option for beginners because any loss of balance is harder to correct.

To perform it, place an Olympic bar on the upper back, as in a traditional squat. It is recommended to take it from a rack or power cage, so you can start the exercise from a safe position and return the bar to the support when finished.

This variant can be interesting for people who already master the Bulgarian split squat with dumbbells and need more load to continue progressing. It also fits into strength routines where unilateral work with greater intensity is sought.

For this type of work, Olympic bars and weight plates allow for progressive load adjustment. Still, it is not always necessary to switch to the bar. For many people, well-chosen dumbbells, good technique, and a full range of motion are enough to achieve great muscle stimulation.

The Bulgarian split squat with a barbell must be done with special attention to stability. If the load forces you to shorten the range of motion too much, twist your body, or lose knee alignment, it is better to reduce weight and prioritize technique.

Bulgarian split squat at home

The Bulgarian split squat at home is one of the best options to train legs with little equipment. You don’t need a specific machine or much space. With a stable bench and some external load, you can do a very complete workout.

Once you control the technique, you can add one dumbbell, two dumbbells, or work with more repetitions. You can also increase difficulty by making the descent slower or adding a pause at the bottom.

The most important point is the stability of the rear support. It is not advisable to use chairs that move, surfaces that are too high, or unstable supports. A weight bench is safer and more comfortable because it allows you to place the rear foot firmly.

This variation is especially useful for people who train at home and want to work glutes and quadriceps without relying on large machines. Additionally, it can be combined with lunges, Romanian deadlifts, hip thrusts, or squats to create a fairly complete lower body routine.

The Bulgarian split squat at home is also useful because it allows progression in many ways without needing much equipment. You can increase repetitions, add load with dumbbells, slow down the descent, or pause at the bottom to increase time under tension.

Load progression in the Bulgarian split squat

The Bulgarian split squat allows progression in many ways. Not everything depends on adding more weight. You can also improve technique, increase range of motion, better control the descent, or use more demanding variations.

Level	Sets and repetitions	Recommendation
Beginner	2-3 sets of 10-12 repetitions per leg	Bodyweight or light dumbbells.
Intermediate	3-4 sets of 8-12 repetitions per leg	Moderate dumbbells and controlled descent.
Advanced	3-5 sets of 5-8 repetitions per leg	Heavy dumbbells or barbell, prioritizing stability.
Hypertrophy	3-4 sets of 8-15 repetitions per leg	Medium load and full range of motion.
Muscular endurance	2-4 sets of 12-20 repetitions per leg	Moderate weight and steady pace.

To gain muscle mass, it usually works well to perform 8 to 12 repetitions per leg with a load that allows maintaining good technique. For strength, you can use fewer repetitions and more weight, as long as the movement remains stable.

For beginners, the priority should be to learn the position. For intermediates, the most interesting aspect is usually progressing with dumbbells. For advanced users, you can work with higher loads, barbell, or more demanding tempos, always without sacrificing knee alignment or hip stability.

When should you include the Bulgarian split squat in your routine?

The Bulgarian split squat can be placed at the beginning or end of the workout, depending on the goal.

If you want to prioritize it, do it at the beginning of the session, after warming up. This way, you will have more energy and can better focus on technique. This option makes sense if your main goal is to improve unilateral strength, glutes, or quadriceps.

If you use it as a complementary exercise, you can place it after squats, leg press, Romanian deadlifts, or hip thrusts. In this case, heavy loading is not necessary. It can serve to add quality volume and work each leg separately.

It also fits very well in full-body routines, especially when you don't have access to many machines. Being a demanding exercise, it can replace other leg movements when training with limited equipment.

In glute routines, it can be combined with hip thrusts, Romanian deadlifts, abductions, or glute kickbacks. In routines more focused on quadriceps, it can be paired with squats, leg press, leg extensions, or lunges.

The important thing is not to do it when you are already too fatigued if you are still learning the technique. The Bulgarian split squat requires coordination and balance, so doing it when very fatigued can cause a loss of movement quality.

What equipment do you need to do the Bulgarian split squat?

The basic equipment for doing the Bulgarian split squat is a stable bench, and to add load, dumbbells are the simplest option since they allow gradual progression and weight adjustment to each person's level.

For more advanced training, you can use an Olympic barbell and plates. This variation allows for heavier loads, although it requires greater technical control.

On the other hand, if you are going to do the Bulgarian split squat with a barbell, it is recommended to use a rack or power cage. This way, you can place the bar at a safe height before starting and return it to the support after finishing the set.

At Fitness Tech, you can find equipment to adapt the Bulgarian split squat for home workouts, personal gyms, or professional spaces.

The Bulgarian split squat is a demanding but very rewarding exercise within a leg routine. When performed correctly, it allows you to work the glutes, quadriceps, and stabilizers with very little equipment. Additionally, it helps improve balance, correct leg imbalances, and increase movement control.

You don't need to start with heavy loads. The important thing is to find a good position, control each repetition, and progress little by little. With the right equipment, you can turn this exercise into a key part of any lower body routine.
