Split squat vs Bulgarian split squat: which one should you do?

Split squat vs Bulgarian split squat is the gym's most unequal rivalry. They're the same lift, separated by one bench, and that bench is the difference between "fine, that was hard" and lying on the floor questioning your choices. Put the back foot on the floor and you have a split squat. Put it on a bench and you have a Bulgarian.

Short answer: the split squat is easier to learn and easier to recover from; the Bulgarian loads the front leg harder through more range at the same weight. Most people should learn the first and spend most of their time on the second. Here's how split squats vs Bulgarian split squats actually differ, and when to use each, whether you write your own sessions or use an alternative to Fitbod for hybrid athletes.

Split squat vs Bulgarian split squat at a glance

Both belong in a single-leg program, and both fit neatly into two strength sessions a week for runners: one bilateral lift for heavy general strength, one single-leg lift for the leg-by-leg work. The question is just which single-leg lift, and when.

What actually changes when you raise the back foot

The front leg does more of the work

In a split squat, the back foot is on the floor and can push. Most people let it, especially when they're tired. Raise it onto a bench and the back leg mostly becomes a kickstand.

That's measurable in the Bulgarian. In a study of the rear-foot elevated split squat in 26 trained men, the lead foot produced a mean of 84.36% of the total vertical force across 715 analyzed reps, and the authors concluded the lift is a valid unilateral exercise. That's why the Bulgarian feels like a single-leg squat and the split squat feels more like a staggered one. If you're picking dumbbells for the bench version, the bulgarian split squat dumbbell guide covers setup and loading in detail.

The range gets bigger

With the back foot raised, the front leg can sink deeper before the back knee runs out of room. More range under load means more work per rep, which is a large part of why the Bulgarian is so much harder at the same weight.

Balance gets harder

One foot on a bench is a smaller, less stable base than two feet on the floor. That's a feature once you're comfortable, and a nuisance in week one. Most wobble in either lift is a stance-width problem, not a balance problem: feet roughly hip-width apart side to side, like train tracks, not a tightrope.

Which works the glutes more?

Both can, and the setup matters more than the exercise.

Stance length is the big lever. A study of split squat step lengths in 20 men found that longer steps increased hip extensor muscle activation while having limited effect on the knee extensors, and suggested a step about equal to leg length as a sensible default. So a longer stance and a slight forward lean from the hips bias the glutes in either version. A shorter stance, upright torso and more forward knee travel bias the quads. That's the whole idea behind split squat form for glutes: you don't need a different exercise, you need a different stance.

The Bulgarian adds a mechanical twist. A comparison of the Bulgarian split squat and the back squat in 20 trained men found both were hip-dominant exercises, with less knee joint displacement in the Bulgarian, and the authors suggested it may suit situations where you want to focus on hip extension while keeping knee demands lower. Note the setup: the Bulgarian was done at 35% of back squat 1RM and the back squat at 70%. It tells you how much less load the single-leg version needs to be hard.

Which builds more strength?

Long-term trials pitting split squats directly against Bulgarians are hard to find. What does exist compares the Bulgarian with the back squat. In a 5-week trial in academy rugby players, training only with rear-elevated split squats or only with back squats produced similar improvements in back squat strength, 40 m sprint time and change-of-direction speed. Small study, short timeframe, young athletes.

So the practical answer is about loading, not magic. The Bulgarian makes the front leg work harder per kilogram, so it's the better strength tool once you can balance. The split squat lets you handle more total load with less wobble, which makes it the better learning tool and a good choice when you want lots of quality reps without wrecking your legs.

When to choose the split squat

• ›You're new to single-leg work. Learn the pattern with both feet down first.
• ›Your hip flexors complain on the bench. The back-leg stretch is much milder.
• ›You want a lighter session. Before a busy running week, or in a race build.
• ›Warm-ups. A few bodyweight split squats before heavier lower-body work.
• ›Your gym has no free bench. It happens.

When to choose the Bulgarian split squat

• ›You can do two controlled sets of ten bodyweight split squats per leg. That's your entry ticket.
• ›You want maximum single-leg work with minimum load. Your lower back will appreciate not carrying a heavy bar.
• ›You train at home with limited dumbbells. The Bulgarian makes light weights hard.
• ›You want to expose left-right differences. The back leg can't cover for the front.

How the split squat and the Bulgarian compare with other single-leg lifts

The family is bigger than two lifts. The lunge is the split squat with a step in and out every rep, which adds balance and deceleration but limits load; our guide to split squat vs lunge goes through when each makes sense. Step-ups are the simplest of the lot. In short, step-ups vs lunges vs Bulgarian split squats trade off range, load and how easy each is to recover from, and the Bulgarian is the one you can push heaviest.

Single-leg work also doesn't replace bilateral squats. A heavy squat once a week alongside a Bulgarian covers both sides of the coin. For the barbell side, back squat form is the place to start, and if you're choosing between front-loaded options, goblet squat vs front squat mostly comes down to how much load you need.

How to program them

Coaching conventions, not commandments. Reps are per leg. RPE 8 means about two reps left in reserve.

A simple progression: bodyweight split squat, loaded split squat, bodyweight Bulgarian, loaded Bulgarian. When you move up a level, drop the load and rebuild. A 20 kg split squat does not become a 20 kg Bulgarian on day one.

For runners: load, soreness and scheduling

Running is a single-leg sport, so both lifts are relevant. The catch is that the work needs to be heavy enough to count. A 2024 meta-analysis on middle- and long-distance runners found high-load strength training (at least 80% of one-rep max) improved running economy, while submaximal loads did not show the same benefit. Bodyweight split squats for sets of 30 are a warm-up. Heavy Bulgarians for sets of six are strength work.

Scheduling follows the usual rules:

• ›Never heavy single-leg work the day before intervals or the long run. Bulgarians in particular leave the front-leg glute and back-leg hip flexor sore for days at first.
• ›Put it on an easy-run day, or on a hard-run day after the run, a few hours apart if you can.
• ›Introduce Bulgarians in a base phase, not two weeks out from a race. Start with two light sets.
• ›In a race build, keep the load and cut the volume, or switch to the split squat to keep soreness down.

How exrsz handles split squats and Bulgarians

exrsz builds a periodized plan from your goal, schedule, level and equipment, so you get the split squat while you're learning and the Bulgarian once you're ready, with the load your dumbbells allow. It places single-leg work around your runs in one plan, adapts the load each week to what you actually lifted, and reshuffles sessions you miss.

FAQ

Is a Bulgarian split squat harder than a split squat?

Yes, at the same weight. Raising the back foot shifts more of the work to the front leg and adds range; a study of the rear-foot elevated split squat found the lead foot produced about 84% of total vertical force.

Split squats vs Bulgarian split squats: which is better for glutes?

Either works if you set it up for glutes: a longer stance and a slight forward lean. A step-length study found longer split squat stances increased hip extensor activation.

Should beginners do split squats or Bulgarian split squats?

Start with split squats. Once you can do two controlled sets of ten per leg with bodyweight, move to the Bulgarian.

Can Bulgarian split squats replace back squats?

For many goals, they can do a lot of the same job. A 5-week trial in rugby players found rear-elevated split squat training and back squat training improved squat strength and sprint times similarly.

How high should the bench be for a Bulgarian split squat?

About knee height or a little lower. Higher mostly stretches the back hip flexor harder without making the front leg work more.
