Dumbbell Bulgarian Split Squat

The dumbbell Bulgarian split squat is a powerful exercise that targets muscles in the lower body. It’s a compound movement that simultaneously builds strength in multiple muscle groups. Isolating each leg helps correct muscle imbalance and can lead to significant gains in balance, strength, and muscle development.

This guide will walk you through the correct technique to safely perform the Bulgarian split squat. We will provide expert tips to help you avoid common mistakes and maximize its benefits. 

How To Do

  1. Stand a few feet in front of a bench or step with a dumbbell in both bands. Grasp the head of the dumbbell with your palms facing the floor and hands at shoulder height. 
  2. Place the top of one foot on the bench behind you. Your front leg should be far enough forward so that when you squat, your knee stays over your ankle.
  3. Take a deep breath in and engage your core. Keep your torso upright, and lower your body by bending your front knee. Your back knee should drop straight down toward the floor.
  4. Continue lowering until your front thigh is parallel to the ground or as low as comfortable.
  5. Press through your front heel to return to the starting position. Exhale at the same time.
  6. Complete the desired number of reps, then switch legs and repeat.

Tips From Expert

  • Focus on a point straight ahead of you to help maintain your balance.
  • Engaging your core will assist with stability while also supporting your lower back.
  • Optimal positioning will ensure a safe and effective workout. Your front foot needs to be far enough forward that your knee doesn’t extend past your toes during the squat. Make sure most of your weight is on your front heel. This protects the knee joint and maximizes muscle engagement.
  • Perform the exercise slowly and with control. Avoid bouncing at the bottom of the movement to maintain muscle tension and prevent injury.

Optimal Sets and Reps

It’s important to tailor your sets and reps to your fitness goals. This helps to maximize the benefits of the dumbbell Bulgarian split squat. Here are some guidelines to help you.

Optimal Sets & Reps of Dumbbell Bulgarian Split Squat

How to Put in Your Workout Split

The dumbbell Bulgarian split squat can help enhance your lower limb strength and stability. Add it to your 5-day working split or one of the following common training splits.

  • Upper/Lower Split — Include the dumbbell Bulgarian split squat on lower body day. Include it after compound lifts like squats or deadlifts for targeted muscle work.
  • Full Body Split — Incorporate it as your main primary lower-body exercises, paired with upper-body movements to balance the session.
  • Push/Pull/Legs Split — On leg day, add it after leg presses and squats to focus on single-leg strength and stability.

To calculate how much weight to lift, you will need to know your one repetition maximum (1RM). This is the heaviest weight you can successfully lift for a single repetition of an exercise while maintaining proper form.

  • For strength training and powerlifting, use heavy weights with low reps, aiming for 80%–100% of your 1RM.
  • For hypertrophy, opt for moderate weights, 60%–80% of your 1RM.
  • Use lighter weights for endurance training, 40%–60% of your 1RM with high reps.

For strength training and powerlifting, rest periods between sets are longer, typically lasting two to three minutes. In contrast, for hypertrophy and endurance training, rest periods are shorter, ranging from 45–90 seconds.

Primary Muscle Groups

Quadriceps

Muscles located at the front portion of your upper legs, below your pelvis and above your knees. Consists of four parts.

Quadriceps 

The quadriceps are the large muscles that stretch from the pelvis to below the knee. They’re located at the front of the thigh. Your quadriceps are made up of four parts that contribute to movements that occur at the hip and knee joints.

During the split squat, the quads are heavily engaged during both the lowering and lifting phases of the movement. They provide stability and strength to propel the body upwards against gravity, carrying your body weight and the dumbbells.

Mean muscle activation in the quads ranged from around 30% to just over 70% during the squat. The innermost quad muscle takes most of the load due to its important role in stabilizing the kneecap during movement.

Secondary Muscle Groups

Gluteus

Large, superficial muscles located at your buttocks just below your lower back area.

Hamstrings

Muscles located at the back of your upper leg, below your glutes and above your calves. Consists of three muscles.

Erector Spinae

Muscles that span the entire length of your spine on either side.

Hip Adductors

Muscles located at the upper inside part of your legs between your quads and hamstrings.

Gluteus 

The gluteal muscles consist of three muscles that make up the buttocks. These muscles have important roles in moving the hip into a straight position, rotating it outwards, and stabilizing the pelvis. Without pelvic stability, we would have a hard time walking, running, or standing on one leg.

During the split squat, the glutes straighten and stabilize the hip as you rise from the squat position. Stabilizing the outer hip is needed to maintain balance on one leg, and it prevents the knee from caving inwards. In the same study as above, the glutes activate at an average of 50% of a maximal muscle contraction, playing an important supporting role.

Hamstrings

The hamstrings are three large muscles at the back of the thigh, stretching from the pelvis to below the knee. Hamstrings bend the knee, straighten the hips, and support the pelvis and knee joint. Functionally, they play a key role in decelerating the leg during walking and stopping the knee from bending backward.

During the standing part of the split squat, they support the glutes to straighten the hip. During the lowering part of the exercise, they slowly lengthen to control the descent, known as an eccentric muscle contraction. They contribute to balancing on one leg and stabilizing the knee joint.

Hip Adductors

The hip adductors are a group of muscles on the inner thigh running between the pelvis and upper leg bone. One of the five attaches below the knee to the lower leg bone. They are responsible for moving the legs towards or across the body, such as when you cross your legs.

They are hip stabilizers, assisting with posture and balance when changing directions during walking or running activities. During the split squat, they stabilize the hips and stop the thigh from moving from side to side. In the upward phase of the squat, they support the glutes and quads to generate the force to stand.

Erector Spinae

The erector spinae is a group of muscles extending along the spine. They go from the lower back to the upper back and neck. Their role is to maintain an upright posture, provide spinal stability, and enable the spine to twist and bend sideways.

Their role during the split squat is to provide spinal stability and maintain an upright posture. Rounding the back would compromise the effectiveness of the exercise and increase the risk of injury. When using dumbbells, erector spinae provide support, distributing the weight across the back and core, preventing strain on one area.

Who Should Do It? 

Athletes

The Bulgarian split squat helps improve one-sided leg strength, balance, and stability, which are essential for athletic performance. It can enhance power and explosiveness, particularly for sports that involve running, jumping, and changing directions.

It has been recommended as a great exercise for athletes that require explosive power performance in one leg. For example, a long jump athlete may benefit from being able to focus on strengthening their lead leg.

It also improves balance and stability by engaging the core and lower body stabilizer muscles, reducing the risk of injury. Overall, this exercise can contribute to stronger, more resilient, and better-coordinated athletes.

Rehabilitation Patients

The split squat is useful for those recovering from lower body injuries, as it allows for controlled, single-leg loading. It’s been recommended as a great low-impact exercise, focusing on hip strengthening while minimizing stress on the knee joint.

It’s been used in early-stage knee rehab to isolate and strengthen the hip stabilizers without compromising the knee joint. Although it should be noted that this is condition-dependent, there will still be loaded force on the knee.

Those Seeking Functional Strength

The dumbbell Bulgarian split squat puts emphasis on single-sided movement, balance, and coordination training. It mimics real-life movements and helps improve functional strength and stability. Strength and stability on one leg are essential for activities such as walking, climbing stairs, and carrying objects.

As we age, we lose muscle mass, so building strength with this exercise is key to healthy aging. By strengthening the quads, glutes, and hamstrings, and stabilizing muscles, it improves overall lower body strength and mobility. It makes everyday activities easier and reduces the risk of falls or injuries.

Who Should Not Do It?

People With Poor Balance

The dumbbell Bulgarian split squat requires significant stability to perform correctly. People with conditions that impact their balance, or poor balance in general, may find this exercise challenging.

Poor balance increases the risk of falling or losing control during the movement, which can lead to injuries. Insufficient balance can prevent proper form, reducing the effectiveness of the exercise and potentially causing undue strain on your joints.

If you want to try the exercise but are concerned about your technique, speak to a personal trainer. They can advise on the correct form or provide a safer alternative exercise if you are unsafe doing the squat split.

People With Hip Issues

The Bulgarian split squat is a low-impact exercise that’s easier on joints. This may reduce injury risk, which may protect them from degeneration longer-term. However, reducing increased stress on the joints requires the ability to do the movement with the correct form.

If you have poor core stability, your ability to maintain a neutral spine is decreased during a squatting position. This can result in increased stress on the front of the hip joint. Those with existing hip problems experiencing discomfort with split squats should seek medical advice to avoid exacerbating their condition.

Those With Poor Core Control

Core stability is key to supporting our spine and maintaining correct posture to avoid pain and injury. The Bulgarian split squat exercise requires significant core stability to maintain proper form and balance.

Poor balance can lead to improper alignment and increased strain on the lower back and knees, increasing injury risk. It may also exacerbate existing injuries while hindering the effectiveness of the exercise. This will prevent the targeted muscles from being properly engaged and reduce the benefit of the exercise.

Benefits Of The Exercise

Supports Balance

Maintaining balance is key to performing everyday activities safely and efficiently. It allows smooth, controlled movements like walking, running, and stair climbing and prevents falls and injuries.

The dumbbell Bulgarian split squat significantly enhances balance by requiring one-legged stability and strength. During the movement, the body must engage the core and stabilize muscles, which strengthens them.

It targets the glutes, hamstrings, hip adductors, and core muscles, which help stabilize the pelvis and maintain balance. The exercise also challenges and improves coordination, leading to better overall balance and stability in everyday activities.

Improves Strength

Compound movements involve exercises that activate multiple muscle groups simultaneously. This makes them highly effective for developing muscle strength and coordination. The dumbbell Bulgarian split squat is an effective exercise for building strength in the knee, hip, and core muscles.

By isolating each leg individually, it provides a larger exercise stimulus. The need to stabilize the body throughout the movement also engages the core and smaller stabilizing muscles.

This increases muscle strength and endurance in the primary working muscles but also improves overall muscular coordination and balance. This can lead to greater strength gains and functional performance.

Enhances Flexibility

Stretching is one of the most common ways to lengthen our muscles and improve our range of motion. The dumbbell Bulgarian split squat enhances flexibility by promoting a deep range of motion in the hips, knees, and ankles.

As you lower into the squat, the hip flexors and quads of the rear leg are stretched. Meanwhile, the front leg’s glutes and hamstrings are actively engaged and lengthened. This dynamic stretching improves the flexibility of these muscle groups over time.

*Expert tip: Incorporate cool-down exercises at the end of your workout to aid overall recovery and maintain flexibility in your muscles.
