🎯 Setup

Starting Position

1. Bench height: 12-18 inches (standard bench works perfectly)
2. Position: Stand 2-3 feet in front of bench, facing away
3. Back foot: Place top of back foot (laces down) on bench
4. Front foot: Position so when you lower, shin stays vertical or near-vertical
5. Stance width: Front foot slightly forward of where it would be standing normally
6. Posture: Chest up, core engaged, shoulders back
7. Balance: Find stability before adding load

Finding Your Distance

Distance Too Close	Distance Too Far	Just Right
Front knee shoots way past toes	Back leg overly stretched, can't balance	Front shin vertical to slight forward angle
Excessive forward lean	Feel pull in back hip flexor at top	Balanced, stable feel

Setup Cue

"Think of it as a single-leg squat where your back leg is just lightly resting for balance — 90% of work is in the front leg"

Equipment Setup

Equipment	Position	Notes
Bench	12-18" high	Standard bench, box, or couch works
Dumbbells	At sides	Start light (10-15 lbs)
Barbell	Across back	Advanced; requires excellent balance
Pad (optional)	Under back foot	If top of foot gets uncomfortable

🔄 Execution

The Movement

🔝 Starting Position

What's happening: Establishing stable split stance

1. Back foot elevated on bench (laces down)
2. Front foot flat on ground, full foot contact
3. Torso upright, slight forward lean acceptable
4. Weight 90% on front leg
5. Arms at sides (or holding dumbbells)
6. Breathing: Big breath in, brace core

Balance note: Take time to find stability before moving

Feel: Front leg loaded and ready, back leg lightly touching bench

⬇️ Lowering Phase

What's happening: Controlled descent into split squat

1. Lower hips straight down (vertical drop)
2. Front knee bends, tracking over toes
3. Back knee drops toward floor
4. Keep torso upright or slight lean
5. Front heel stays flat on ground
6. Breathing: Hold breath or controlled inhale

Tempo: 2-3 seconds

Depth: Until front thigh is parallel (or back knee near floor)

Feel: Front quad and glute stretching/loading, back hip flexor stretching

⏸️ Bottom Position

What's happening: Maximum stretch and muscle tension

1. Front thigh parallel to ground (or just above)
2. Back knee 3-6 inches from floor
3. Front knee aligned over ankle/toes
4. Torso upright, core tight
5. All weight on front leg
6. Front heel pressed into ground

Key position: This is the money position — maximum muscle activation

Feel: Deep stretch in front hip and quad, back hip flexor stretched

⬆️ Driving Up

What's happening: Powerful drive back to start

1. Push through front heel/whole foot
2. Drive front leg into ground
3. Extend front knee and hip simultaneously
4. Keep torso stable, don't rock forward
5. Return to starting position
6. Breathing: Exhale forcefully through sticking point

Tempo: 1-2 seconds (controlled power)

Feel: Front quad and glute firing maximally

Key Cues

Primary Cues

• "Push the floor away, not the bench" — all force from front leg
• "Sit straight down between your hips" — prevents excessive forward lean
• "Front heel glued to the floor" — ensures posterior chain engagement

Tempo Guide

Goal	Tempo	Example
Strength	2-0-1-1	2s down, no pause, 1s up, 1s rest at top
Hypertrophy	3-1-2-0	3s down, 1s pause, 2s up, no rest
Endurance	2-0-2-0	2s down, no pause, 2s up, continuous

💪 Muscles Worked

Activation Overview

Primary Movers

Muscle	Action	Activation
Quadriceps	Knee extension — straightening front leg	█████████░ 90%
Glutes	Hip extension — driving up from bottom	█████████░ 85%

Secondary Muscles

Muscle	Action	Activation
Hamstrings	Hip extension assist, knee stability	██████░░░░ 60%
Calves	Ankle stability, minor push-off	█████░░░░░ 45%

Stabilizers

Muscle	Role
Core	Maintain upright torso, prevent rotation during single-leg loading
Hip Stabilizers (Glute Med/Min)	Balance, prevent hip drop, control pelvic position

Muscle Emphasis

Bulgarian split squats are THE BEST exercise for quad and glute hypertrophy because:

• Single-leg loading allows very deep stretch without needing massive weights
• Elevated back foot increases front leg ROM significantly
• Can load heavily with just dumbbells (no squat rack needed)
• Activation rivals or exceeds bilateral squats at lower absolute loads
• Fixes left-right imbalances that bilateral exercises hide

⚠️ Common Mistakes

Mistake	What Happens	Why It's Bad	Fix
Too much weight on back foot	Using back leg to push	Defeats single-leg purpose	Focus all force through front heel
Front foot too close	Knee shoots past toes	Excessive knee stress	Move front foot 6-12" forward
Excessive forward lean	Torso drops toward floor	Less glute work, balance issues	Chest up, core tight
Heel lifting	Front heel comes off ground	Reduces glute activation, toe stress	Push through heel, check stance
Bench too high	Overstretched, unstable	Poor form, injury risk	Use 12-16" bench
Rushing the reps	Fast, bouncy movement	Less time under tension, injury risk	Control the tempo: 2-3s down

Most Common Error

Front foot positioned too close to bench — this creates excessive forward knee travel and makes the exercise quad-dominant in a problematic way. Move your front foot farther forward until your shin is vertical at the bottom.

Self-Check Checklist

• Back foot is lightly resting (not pushing)
• Front shin is vertical or near-vertical at bottom
• Front heel stays flat throughout
• Can balance without wobbling excessively
• Feel it primarily in front leg, not back leg

🛡️ Safety & Contraindications

Who Should Be Careful

Condition	Risk	Modification
Knee pain (anterior)	Compression forces	Check front foot position; try reverse lunges
Hip flexor tightness	Back leg stretch discomfort	Lower bench height, stretch hip flexors
Poor balance	Falling, compensation	Hold rail/wall, or use standard split squat
Lower back issues	Spinal loading with barbell	Stick with dumbbells

Stop Immediately If

• Sharp knee pain in front leg
• Hip flexor sharp pain (not stretch) in back leg
• Repeated balance loss
• Lower back pain (with load)

Balance Considerations

Bulgarian split squats are challenging for balance:

Issue	Solution
Wobbly front leg	Widen stance slightly (6" apart), strengthen stabilizers
Back foot sliding off	Use non-slip surface on bench, or add pad
Tipping sideways	Hold light weight (helps counterbalance), practice bodyweight first

Safe Loading

Weight Range	Notes
Bodyweight	Learn the movement, establish balance
10-20 lbs	Initial loading phase
20-40 lbs	Most people's sweet spot for hypertrophy
40-60+ lbs	Advanced; requires excellent form
Barbell	Only after mastering heavy dumbbell version

Loading Tip

Bulgarian split squats create huge stimulus at relatively "light" weights because of single-leg loading. Don't rush to heavy weights — perfect form with 30-40 lb dumbbells is more effective than sloppy form with 60 lbs.

🦴 Joints Involved

Joint	Action	ROM Required	Stress Level
Hip	Flexion/Extension (front), extreme extension (back)	90-100° front flexion, full extension back	🔴 High
Knee	Flexion/Extension (front leg primarily)	90-100° flexion	🟡 Moderate
Ankle	Dorsiflexion (front), plantarflexion (back)	15-20°	🟢 Low-Moderate
Spine	Neutral stability	Minimal movement	🟢 Low

Mobility Requirements

Joint	Minimum ROM	Test	If Limited
Hip Flexor (back leg)	Full extension plus more	Can you elevate back foot without arching lower back?	Lower bench, stretch hip flexors daily
Hip Flexion (front)	100°	Deep lunge or squat	Work on hip mobility
Ankle	15° dorsiflexion	Wall ankle test	Heel-elevated shoes, calf stretches

Joint Health Note

Hip flexor flexibility is critical. The elevated back foot creates an intense hip flexor stretch. If you feel sharp pain (not stretch) in the front of your back hip, lower the bench height or work on hip flexor mobility before progressing.

❓ Common Questions

Where should I feel this exercise?

Primarily in your front leg — quads and glutes. You'll also feel a stretch in your back leg's hip flexor. If you feel it more in your back leg than front, you're pushing off the back foot too much. Focus all force through your front heel.

How far forward should my front foot be?

Position it so your shin is vertical or slightly forward when at the bottom. Start by placing it 2-3 feet from the bench and adjust. Taller people typically need their front foot farther forward.

Should I lean forward or stay upright?

Slight forward lean (10-20°) is natural and fine. Staying completely upright emphasizes quads more. Leaning forward slightly shifts emphasis to glutes. Avoid excessive forward lean that looks like you're falling forward.

Can I do these every leg day?

Yes, 1-2x per week for most people. They're demanding, so recovery matters. You could do them twice per week with different rep ranges (e.g., Monday: 3x8 heavy, Thursday: 3x15 lighter).

Bulgarian split squat vs. regular lunges — which is better?

Different tools for different goals. Bulgarian split squats are superior for hypertrophy (muscle building) because they allow more load and ROM. Lunges (forward/reverse/walking) are better for athleticism, balance, and when you don't have equipment. Both are valuable.

My back foot hurts on the bench — what should I do?

Place a pad, towel, or Airex pad under your back foot. Some people prefer placing the ball of the back foot on the bench instead of the laces (though this changes the exercise slightly). Experiment to find what's comfortable.

How heavy can I go with Bulgarian split squats?

Very heavy! Advanced lifters can use 60-80+ lb dumbbells per hand or barbell with significant weight. The single-leg nature means you won't match your squat numbers, but 50-70% of your back squat weight total (e.g., if you squat 200 lbs, holding 60-70 lb dumbbells per hand) is achievable.

For Mo

When to recommend this exercise:

• User wants to maximize quad and glute hypertrophy
• User needs to fix left-right strength imbalances
• User has access to minimal equipment (dumbbells + bench/chair)
• User is intermediate or advanced in training
• User wants a single exercise that hits legs comprehensively

Who should NOT do this exercise:

• Complete beginners (start with reverse lunges or split squats)
• Severe balance issues → Suggest Leg Press or Split Squat
• Acute knee injury → Wait for medical clearance
• Very tight hip flexors + unwilling to modify → Will cause discomfort; need mobility work first

Key coaching cues to emphasize:

1. "All your force through the front heel — back foot is just for balance"
2. "Sit straight down between your hips"
3. "Front heel glued to the floor"

Common issues to watch for in user feedback:

• "I feel it more in my back leg than front" → They're pushing off back foot. Cue front heel pressure
• "I keep losing my balance" → Normal at first. May need to widen stance slightly, slow down tempo
• "My back hip flexor hurts" → Distinguish stretch (okay) from pain (problem). May need lower bench or hip flexor work
• "My front knee hurts" → Check front foot position; likely too close to bench. Move forward 6-12"
• "I feel like I'm falling forward" → Cue chest up, engage core, may be too much weight

Programming guidance:

• Pair with: Hip hinge (RDL, leg curl), vertical/horizontal push/pull
• Place after: Main bilateral squat (if doing both)
• Use as main lift: Can be primary leg exercise if training at home
• Typical frequency: 1-2x per week per leg
• Volume: 3-4 sets of 8-15 reps per leg

Progression signals:

• Ready to add weight when: 3x12 bodyweight with perfect balance and form
• Progress weight when: Can complete 3x12 at current weight with 2 RIR
• Try deficit when: Comfortable with 30+ lb dumbbells and want more glute emphasis
• Try barbell when: 50+ lb dumbbells per hand, excellent balance
• Regress if: Consistent balance issues, knee/hip pain, form breakdown

Special programming notes:

• Hypertrophy focus: 3-4 sets of 10-15 reps, moderate weight, 90s rest
• Strength focus: 3-4 sets of 6-10 reps, heavy weight, 2-3 min rest
• Superset option: Can superset with hamstring curl or Nordic curls
• Time efficient: Doing both legs = high volume from one exercise

Why this exercise is special:

• Creates squat-level stimulus with much lighter loads
• Fixes imbalances that bilateral exercises hide
• Minimal equipment needed (perfect for home gyms)
• Less spinal loading than barbell squats
• Research shows equal or greater glute/quad activation vs. back squat
