🎯 Setup

Starting Position

1. Bar position: Rest bar across front delts/clavicle (front rack)
2. Arms: Extend arms straight out in front, parallel to ground
   • Think: "Walking like a zombie" — hence the name
3. Shoulders: Actively elevated to create shelf for bar
4. Unrack: Keep chest tall, unrack with control
5. Stance: Hip to shoulder-width, toes out 15-30°

Equipment Setup

Equipment	Setting	Notes
Bar height	Collarbone level	Should be easy to step under
Safety pins	Just below bottom position	Critical — no hands to catch bar
Collar clips	Always use	Bar can roll without hand control

Setup Cue

"Shoulders up like you're shrugging, arms out like you're sleepwalking — the bar cannot fall"

🔄 Execution

The Movement

⬇️ Descending

What's happening: Controlled lowering with forced vertical torso

1. Breathe in, brace core maximally
2. Break at knees and hips simultaneously
3. "Sit straight down like an elevator" — zero forward lean
4. Keep arms parallel to floor throughout
5. Shoulders stay elevated — don't let them drop

Tempo: 2-3 seconds

Feel: Extreme quad loading, upper back working to maintain posture

Critical: If arms drop or chest collapses, the bar will roll off

⏸️ Bottom Position

What's happening: Maximum depth while maintaining vertical torso

1. Hip crease at or below knee level
2. Knees track forward over toes
3. Arms still parallel to ground — fight to keep them up
4. Chest stays tall — thoracic spine extended
5. Bar remains on shoulder shelf

Common error here: Chest collapsing forward as you fatigue — this makes bar roll. Reset if needed.

⬆️ Ascending

What's happening: Driving straight up through vertical path

1. "Push floor away, chest leads upward"
2. Maintain arm position — don't let them drop
3. Knees extend while torso stays upright
4. Breathing: Exhale through sticking point or hold

Tempo: 1-2 seconds (controlled power)

Feel: Quads burning intensely, upper back fatiguing to hold position

🔝 Lockout

What's happening: Full extension with reset

1. Stand fully tall — hips under shoulders
2. Shoulders remain elevated
3. Arms stay extended forward
4. Reset breath for next rep
5. Maintain shelf for bar

Key Cues

Primary Cues

• "Zombie arms — dead ahead, never drop" — maintains shelf for bar
• "Chest to the sky, shoulders to your ears" — prevents forward collapse
• "Sit straight down between your feet" — eliminates forward lean

Tempo Guide

Goal	Tempo	Example
Technique	3-0-2-1	3s down, no pause, 2s up, 1s reset
Hypertrophy	3-1-2-0	3s down, 1s pause, 2s up, no pause
Strength	2-0-1-1	2s down, no pause, 1s up, 1s reset

⚠️ Common Mistakes

Mistake	What Happens	Why It's Bad	Fix
Arms dropping	Lose shelf for bar, bar rolls forward	Bar falls off, dangerous	Practice holds, reduce weight, strengthen upper back
Chest collapsing	Torso folds forward	Defeats purpose, bar rolls off	Lighten load, cue "chest to sky"
Leaning forward	Hip rise faster than shoulders	Bar shifts forward, defeats drill	Reduce weight, goblet squat first
Shallow depth	Stopping above parallel	Less effective, avoiding weakness	Box squat to proper depth first
Heels rising	Weight shifts to toes	Balance loss, less force	Elevate heels with plates/shoes

Most Common Error

Letting arms drop as you fatigue — this immediately compromises bar security. Use lighter weight and prioritize arm position over depth or reps. Better to stop the set than risk the bar rolling.

Self-Check Checklist

• Arms parallel to ground entire movement
• Shoulders actively elevated ("shrugged up")
• Chest tall, no forward lean
• Knees track over toes (forward travel is normal)
• Bar stays on front delt shelf, doesn't roll

🛡️ Safety & Contraindications

Who Should Be Careful

Condition	Risk	Modification
Shoulder mobility issues	Bar position uncomfortable	Use safety bar or goblet squat
Wrist pain	Bar pressure on wrists	Non-issue (no wrist involvement)
Poor thoracic mobility	Cannot maintain chest-up position	Thoracic mobility work first
Knee pain	Forward knee travel	Box squat to reduce depth

Stop Immediately If

• Bar starts to roll forward off shoulders
• Chest collapses and can't maintain position
• Sharp knee pain with forward tracking
• Loss of balance or control

Critical Safety Notes

1. Always use safety pins — you have no hands to catch the bar
2. Start very light — this is humbling even for strong squatters
3. Don't ego lift — the point is position, not weight
4. Bail by dropping forward — step forward, let bar fall to pins behind you

Safe Failure Protocol

How to bail from a zombie squat:

1. Before failure: Set safeties at proper height (below bottom position)
2. If losing position: Step forward quickly, let bar fall backward onto pins
3. Never try to "save it" — without hands, you can't control the bar
4. Practice the bail — try it with empty bar to know the movement

🦴 Joints Involved

Joint	Action	ROM Required	Stress Level
Hip	Flexion/Extension	110-130° flexion	🟡 Moderate
Knee	Flexion/Extension	120-140° flexion	🔴 High
Ankle	Dorsiflexion	20-25° (more than back squat)	🟡 Moderate
Thoracic Spine	Extension	Significant extension needed	🟡 Moderate

Mobility Requirements

Joint	Minimum ROM	Test	If Limited
Ankle	20° dorsiflexion	Wall test (deeper than back squat)	Elevate heels, ankle mobility daily
Hip	110° flexion	Can you front squat comfortably?	Hip flexor/glute stretches
Thoracic	Good extension	Arms overhead, can you look up?	Foam rolling, extension drills
Shoulder	Comfortable front rack	Can hold bar on front delts?	If no, use goblet variation

Mobility Note

Zombie squats require more ankle dorsiflexion than back squats because of the vertical shin angle. If you lack this, elevate your heels until mobility improves. The thoracic extension demand is also high — if you can't maintain a proud chest, work on upper back mobility first.

❓ Common Questions

Why is it called a "zombie squat"?

The name comes from the arm position — arms extended straight forward like a walking zombie from horror movies. This arms-forward position forces your torso to stay upright to keep the bar from rolling off your shoulders.

How much weight should I use?

Start with just the bar (45 lbs) and master the position. Most people work in the 65-135 lb range. This is not a max strength exercise — it's a teaching tool and accessory movement. If you're using more than 185 lbs, you're probably strong enough to just do regular front squats.

Is this safer than front squat?

Not necessarily. It's actually more technical because you can't use your hands to secure the bar. However, it teaches better position by forcing vertical mechanics. Use it as a stepping stone to front squats, not as a permanent replacement.

My upper back gets tired before my legs — is that normal?

Yes, very normal. The zombie position demands significant upper back and shoulder work to maintain the "shelf" for the bar and keep your arms up. This is actually part of the exercise's value — it builds the positional strength needed for front squats and Olympic lifts.

Can I do this without a squat rack?

Technically yes with very light weight (like a technique bar), but it's not recommended. Getting the bar into position without hands to help is awkward, and you have no safe way to bail if something goes wrong. Always use a rack with safeties.

For Mo

When to recommend this exercise:

• User is learning front squat but struggles with upright position
• User has chronic forward lean in back squats
• User is training for Olympic lifting (clean/snatch receiving position)
• User wants quad-focused work without heavy spinal loading

Who should NOT do this exercise:

• Severe thoracic mobility limitations → Suggest Goblet Squat
• Acute shoulder issues affecting front rack → Suggest Safety Bar Squat
• Complete beginners → Start with Goblet Squat first
• Those seeking max strength → Better to do Front Squat

Key coaching cues to emphasize:

1. "Zombie arms — dead ahead, never drop"
2. "Chest to the sky, shoulders to your ears"
3. "Sit straight down between your feet"

Common issues to watch for in user feedback:

• "The bar keeps rolling forward" → Arms dropping or chest collapsing; reduce weight
• "My upper back fatigues fast" → Normal; this builds position strength
• "I can't keep my arms up" → Use lighter weight or regress to goblet variation
• "My knees hurt going forward" → Normal with vertical torso; reduce depth if needed

Programming guidance:

• Pair with: Romanian deadlift, upper body push; avoid before heavy cleans
• Avoid same day as: Heavy front squats (redundant) or immediately before Olympic lifts
• Typical frequency: 1-2x per week as accessory/technique work
• Volume: Keep moderate (3-4 sets of 6-10 reps)

Progression signals:

• Ready to progress when: Can maintain perfect position with 95-135 lbs for 3x8
• Progress to: Front Squat with hands securing bar
• Regress if: Cannot maintain arm position or chest-up posture
