Compound — lower body
Dumbbells or barbell and a bench
The Bulgarian split squat is one of the most demanding and effective single-leg exercises. It exposes and corrects strength differences between legs and drives huge quad and glute growth.
Muscles worked
The Bulgarian split squat is widely disliked for a good reason: it is genuinely hard, and it removes the ability to hide a weaker side. That is exactly the argument for doing it. It builds quads and glutes with a fraction of the spinal load of a barbell squat, which makes it valuable when your back needs a break but your legs do not.
Technique
Common mistakes
Front foot too close to the bench
Fix: The knee ends up far past the toes and the quad takes everything. Step further forward until the shin is near-vertical at the bottom.
Rear foot placed too high
Fix: A high bench forces the hip flexor into an aggressive stretch and destabilises the position. Knee height or slightly below is right.
Pushing off the back foot
Fix: The rear leg is for balance only. Drive through the front heel — if the back leg is working, you are doing a lunge.
Starting far too heavy
Fix: The balance demand alone is significant. Start with bodyweight and only add dumbbells once you can do 3×10 per side without wobbling.
Sets and reps
How to progress
Add reps per side before load — 3×8 to 3×12 is real progress. Then add dumbbells in 2 kg steps. Because it is single-leg, total systemic fatigue is low, so it can be trained twice a week without the recovery cost of heavy squats. Always start the set with your weaker side and match the reps on the stronger one.
Variations
Front-foot-elevated split squat
Raising the front foot increases range and glute involvement.
Goblet split squat
Dumbbell at the chest, which helps balance and keeps the torso upright.
Deficit split squat
Front foot on a plate for a deeper stretch at the bottom.
Frequently asked questions
The split squat is more stable, so you can load it harder and focus on the target leg. Lunges add a stepping component and more balance work. For pure leg building, split squats win.
Around knee height, or slightly lower. Higher benches force the hip flexor into an uncomfortable stretch without adding useful difficulty.
Torso angle and foot position. Leaning forward with the front foot further away favours the glutes; staying upright with the foot closer favours the quads.
