Bulgarian Split Squat: technique, muscles and program for 2026

The Bulgarian split squat is a unilateral leg exercise where your front foot stands on the floor and your rear foot rests on a bench. You drop deep on one leg, which intensively loads your quadriceps, glutes and hamstrings. Because you train your legs separately, you detect strength differences and improve balance and stability. With the right technique this belongs among the most effective leg exercises for strength and muscle mass.

What is the Bulgarian split squat?

The name comes from Bulgaria, where weightlifting coaches in the 1980s popularised the exercise as a supplement to Olympic lifting. Technically it is a split squat: you stand in a wide split stance and place the instep of your rear foot on a bench or box of about 40-50 cm. Because you load one leg at a time, you train unilaterally. That makes the exercise more effective than a regular squat for detecting and correcting strength differences between left and right, and ideal for athletes who want to build functional leg strength.

Which muscles do you train with the Bulgarian split squat?

Primary muscles

The quadriceps form the engine of the exercise: all four heads work together to extend the knee during the push back up. Directly after that the gluteus maximus follows, the large glute muscle that drives hip extension on the front leg.

Secondary muscles and core

The hamstrings support hip extension and stabilise the knee, especially if you tip the torso slightly forward. The gluteus medius works as a lateral stabiliser of the hip and prevents the knee from collapsing inward. The hip flexor of the rear leg is dynamically stretched, which benefits your hip mobility. At the same time your oblique abs and deep trunk muscles are continuously active: they keep you stable and prevent rotation during every rep.

Bulgarian split squat execution in 8 steps

Starting position and setup

Place a bench or plyo box of 30-50 cm height behind you. Step 60-80 cm forward for a generous split stance. Place the instep of your rear foot flat on the bench. Your front foot points straight ahead or slightly outward, knee above the second toe. Torso upright, chest up, shoulders back. Start with body weight or two dumbbells of 5-10 kg per hand.

The movement down

Breathe in and brace your core. Lower in three counts by bending hip and knee of your front leg. The rear knee descends towards the floor without touching the gyms in Hem. Your torso tilts slightly forward from the hip and your back stays straight. The weight distributes via the heel and the ball of your front foot.

Pushing back up

Drive through the heel of your front foot and extend hip and knee at the same time. Breathe out during the extension. Do not fully lock out the knee at the top so the muscle stays under continuous tension. Complete all reps on one leg before you switch. Then apply the recovery rest that fits your program.

Common mistakes and how to avoid them

Knee shoots far over the toe. This indicates a split stance that is too short. Place your front foot further forward. Some knee travel is normal, but pain at the kneecap is a signal to lengthen the stance.

Stance is too short. If your rear knee quickly touches the floor and your hip barely sinks, you are standing too close to the bench. A wider stance gives more depth and muscle activation. source: WHO confirms that too rapid load build-up is the main cause of knee problems in squat variants.

Torso falls far forward. This points to too heavy weight or a weak core. Slight forward lean from the hip is correct, but the back should not round.

Sets, reps and progression: a 4-week program

Are you new to strength training?

Program for beginners

• Week 1-2: 3 sets x 10 reps per leg, body weight or 2x5 kg, 90 seconds rest.
• Week 3: 3 sets x 10-12 reps, 2x8 kg per hand, 90 seconds rest.
• Week 4: 3 sets x 12 reps, 2x10 kg per hand, 90 seconds rest.

Focus on technique over weight. After two weeks you already notice a difference in balance and coordination. Muscle soreness in glutes and quadriceps after the first session is normal and decreases as your body adapts.

Program for advanced lifters

• Week 1: 4 sets x 8 reps per leg, 2x18-22 kg dumbbells or barbell 50-60 kg, 2 minutes rest.
• Week 2: 4 x 8, weight +2.5 kg per side.
• Week 3: 4 x 6, maximum weight of this block, 3 minutes rest.
• Week 4: Deload: 3 x 10 with 70 percent of the week 3 weight.

Variants and alternatives

No bench available, or knee issues? There are good options. The regular split squat you do without elevation: both feet stay on the floor, which loads the hip flexor less and makes the exercise more accessible. The reverse lunge trains similar muscles with less stability demand. The step-up on a box of 30-40 cm offers strong quadriceps and glute activation without extra equipment.

Where to train this exercise: home or in the gym?

For the Bulgarian split squat you need at least a stable elevation of 30-45 cm plus free space for the split stance. At home a sturdy chair or stool suffices. In the gym you use an adjustable bench or plyo box in the functional training area. Gymsearch has compared more than 1,200 Dutch gym locations: from Basic-Fit and SportCity in gyms in Amsterdam, gyms in Rotterdam and gyms in Utrecht to smaller local gyms. Whether you train at home or in the gym: the Bulgarian split squat deserves a fixed place in your leg program.
