🎯 Setup

Starting Position

1. Basic setup: Follow standard leg press setup (see Leg Press)
2. Foot position:
   • Width: Hip-width or slightly narrower (6-10 inches apart)
   • Placement: Center to slightly lower on platform
   • Angle: Toes pointing straight ahead or slightly out (5-10 degrees max)
3. Lower back: Press flat against pad — critical with narrow stance
4. Check alignment: Knees should track straight over toes, not caving inward
5. Hands: Grab handles for stability
6. Release safeties: Push platform up, engage safety release

Stance Comparison

Stance Width	Foot Position	Primary Emphasis
Narrow (this exercise)	6-10 inches apart	Outer quads (vastus lateralis)
Standard	Shoulder-width	Balanced quads/glutes
Wide	1.5x shoulder-width	Inner quads, glutes, adductors

Setup Cue

"Feet close together, toes forward — imagine you're doing a narrow squat on the platform"

Knee Stability Required

Narrow stance requires more knee stability and control. If you have knee issues or are new to leg press, start with standard stance first.

🔄 Execution

The Movement

⬇️ Lowering

What's happening: Controlled descent with narrow knee tracking

1. Take a breath and brace core
2. Slowly lower platform by bending knees
3. Critical: Knees must track straight — more challenging with narrow stance
4. Keep lower back flat against pad
5. Breathing: Inhale as you lower

Tempo: 2-3 seconds

Feel: Concentrated tension in quads, especially outer thighs

Narrow stance challenge: Greater demand on knee stability — knees want to cave inward

⏸️ Bottom Position

What's happening: Deep knee flexion, narrow stance increases ROM

1. Lower until knees reach 90 degrees or slightly more
2. Watch for: Knees caving inward (valgus) — common with narrow stance
3. Lower back must stay flat on pad
4. Narrow stance may allow deeper range than wide stance
5. Brief pause or immediate reversal

Form check: Are your knees tracking straight over your toes, or collapsing inward? If collapsing, reduce weight or widen stance.

⬆️ Pressing

What's happening: Driving through heels with narrow base

1. "Push through your heels" — drive platform away
2. Actively push knees out to prevent valgus collapse
3. Maintain narrow stance position (feet don't slide)
4. Press evenly with both legs
5. Breathing: Exhale as you press

Tempo: 1-2 seconds (controlled, powerful)

Feel: Intense quad burn, outer thighs working hard

🔝 Lockout

What's happening: Full leg extension from narrow base

1. Press until legs are nearly straight
2. Keep slight bend in knees (don't hyperextend)
3. Maintain tension — don't lock and rest
4. Reset breath for next rep

Narrow stance benefit: Less stable at top, requires more quad control

Key Cues

Primary Cues

• "Knees straight ahead, don't let them cave" — critical for safety
• "Narrow stance, big quad focus" — remind yourself of the target
• "Push through heels" — maximizes quad activation
• "Control every inch" — narrow stance demands precision

Tempo Guide

Goal	Tempo	Example
Strength	2-0-1-0	2s down, no pause, 1s up
Hypertrophy	3-1-2-0	3s down, 1s pause, 2s up
Outer Quad Focus	3-2-2-1	Slow and controlled, pause at top

💪 Muscles Worked

Activation Overview

Primary Movers

Muscle	Action	Activation
Quadriceps (Vastus Lateralis)	Knee extension — outer quad emphasis	█████████░ 90%
Quadriceps (Overall)	Knee extension — primary driver	████████░░ 80%

Secondary Muscles

Muscle	Action	Activation
Glutes	Hip extension	██████░░░░ 60%
Hamstrings	Assist hip extension	█████░░░░░ 45%

Stabilizers

Muscle	Role
Adductors	Work harder to keep knees from caving inward
Core	Stabilize torso with less stable base

Why Narrow Stance Hits Outer Quads

The narrow stance creates a longer moment arm for the vastus lateralis (outer quad). With feet closer together, the outer quad must work harder to:

1. Keep knees tracking straight (resist valgus)
2. Control the deeper range of motion
3. Stabilize the less-stable narrow base

Research shows narrow stance squats and presses increase vastus lateralis activation by 10-15% compared to standard stance.

⚠️ Common Mistakes

Mistake	What Happens	Why It's Bad	Fix
Knees caving inward (valgus)	Knees collapse toward midline	ACL/meniscus stress, injury risk	Lighter weight, "push knees out" cue
Stance too narrow	Feet touching or very close	Unstable, excessive knee stress	Keep hip-width minimum
Partial range	Not lowering fully	Less outer quad activation	Use full ROM, lighter weight if needed
Feet sliding wider	Stance widens during set	Defeats purpose of narrow stance	Focus on maintaining position
Bouncing at bottom	Using momentum	Joint stress, less muscle work	Pause or control reversal
Lower back rounding	Butt lifts off pad	Spinal stress	Reduce depth, focus on back position

Most Common Error

Knees caving inward (knee valgus) — this is the #1 issue with narrow stance leg press. The narrow base makes it harder to keep knees tracking straight. If your knees cave inward, you're at risk for knee injury. Fix: Reduce weight by 20-30%, actively push knees outward, consider slightly wider stance.

Self-Check Checklist

• Feet hip-width or slightly narrower (not touching)
• Knees track straight over toes (no inward collapse)
• Lower back stays flat on pad
• Lowering to at least 90-degree knee angle
• No bouncing at bottom
• Feet stay in same position throughout set
• Slight bend in knees at top

Progression Scheme

Load Expectations

Expect to use 10-20% less weight on narrow stance compared to standard stance leg press. The narrow base is less stable and demands more control. If you leg press 400 lbs standard stance, use 320-360 lbs for narrow stance.

Programming Notes

When to use narrow stance:

• Building outer quad sweep (aesthetics)
• Addressing quad imbalances
• Adding variety to prevent adaptation
• Isolation work after heavy compounds

When NOT to use narrow stance:

• Knee pain or instability
• Beginner to leg press (learn standard first)
• Maximum strength focus (standard stance is stronger)
• Limited knee mobility

🛡️ Safety & Contraindications

Who Should Be Careful

Condition	Risk	Modification
Knee pain	Higher stress on knee joint	Use standard stance instead
Knee valgus tendency	Narrow stance exacerbates collapse	Start with standard, build stability
Limited ankle mobility	Harder to maintain narrow position	Feet higher on platform
Hip impingement	Narrow stance increases hip flexion	Reduce depth, standard stance

Stop Immediately If

• Knees caving inward despite cueing
• Sharp pain in knee (inner or outer)
• Feeling of instability or inability to control platform
• Lower back pain (not muscle fatigue)
• Unusual clicking or popping in knee

Critical Safety Points

1. Master standard stance first — don't jump to narrow stance as a beginner
2. Use less weight — narrow stance is less stable, requires 10-20% less load
3. Watch for knee valgus — if knees cave inward, stop and reduce weight
4. Don't go too narrow — hip-width minimum, feet touching is dangerous
5. Maintain lower back position — narrow stance doesn't change back safety rules

Who Should Skip Narrow Stance

• Beginners: Learn standard leg press first (2-3 months minimum)
• Knee issues: Any history of ACL, meniscus, or patellar problems
• Poor ankle mobility: Limited dorsiflexion makes narrow stance unsafe
• Knee valgus tendency: If knees cave on standard stance, narrow will be worse

Knee Safety Priority

Narrow stance leg press is NOT essential. If you have any knee concerns or your knees cave inward, stick with standard or wide stance. There's no prize for using narrow stance if it risks injury. Wide stance leg press can also build great quads.

🦴 Joints Involved

Joint	Action	ROM Required	Stress Level
Knee	Flexion/Extension	90-110 degrees flexion	🔴 High
Hip	Flexion/Extension	90-110 degrees flexion	🟡 Moderate
Ankle	Dorsiflexion	15-20 degrees	🟡 Moderate
Spine	Neutral stability	MUST stay neutral	🟢 Low (if done correctly)

Mobility Requirements

Joint	Minimum ROM	Test	If Limited
Knee	90 degrees flexion	Seated knee bend	Use standard stance
Ankle	15 degrees dorsiflexion	Narrow squat test	Feet higher on platform or standard stance
Hip	90 degrees flexion	Narrow squat, knees to chest	Reduce depth or standard stance

Knee Stress Consideration

Narrow stance increases valgus stress on the knee (inward collapse force). The knee joint is less stable with a narrow base, and the adductors must work harder to prevent collapse.

Why this matters:

• Greater ACL stress if knees cave inward
• More demand on medial (inner) knee structures
• Requires good knee control and strength

If you have knee issues: Standard or wide stance is safer. Don't force narrow stance.

Joint Angle Comparison

Stance	Knee Stress	Hip Flexion	Ankle Dorsiflexion
Narrow	🔴 Higher	🟡 Moderate	🟡 More required
Standard	🟡 Moderate	🟡 Moderate	🟢 Less required
Wide	🟢 Lower	🟢 Less	🟢 Minimal

❓ Common Questions

Will narrow leg press really build my outer quad sweep?

Yes, but with context. Narrow stance increases vastus lateralis (outer quad) activation by 10-15% compared to standard stance. Over time, this can contribute to better outer quad development. However, your genetics determine your overall quad shape. Narrow stance is ONE tool for quad development, not a magic fix. Combine it with standard leg press, squats, and leg extensions for complete quad development.

How narrow should my feet be?

Hip-width (6-10 inches apart) is ideal for most people. Narrower than hip-width becomes unstable and increases injury risk. Don't let feet touch or get within a few inches — that's too narrow and dangerous. Your knees should be able to track straight over your toes without collapsing inward.

Why do my knees keep caving inward?

This is knee valgus, and it's the #1 issue with narrow stance. Causes: (1) weight too heavy, (2) weak adductors/glutes, (3) poor motor control, (4) stance too narrow. Fix: Reduce weight by 20-30%, actively cue "push knees out," consider slightly wider stance. If it persists, skip narrow stance and stick with standard stance until you build more stability.

Is narrow leg press necessary for quad development?

No — narrow stance is supplementary, not essential. You can build great quads with standard stance leg press, squats, and leg extensions. Narrow stance is a tool for variety and specific outer quad emphasis, but it's not mandatory. If it feels awkward or causes knee issues, skip it.

How much less weight should I use compared to standard stance?

Expect to use 10-20% less weight than standard stance leg press. If you press 400 lbs standard, use 320-360 lbs narrow. The narrow base is less stable and requires more control. Don't ego lift — focus on form and quad contraction.

Can I do narrow leg press if I have knee pain?

Probably not. Narrow stance increases knee stress and demands more stability. If you have knee pain, standard or wide stance is safer. Wide stance actually reduces knee stress and may feel better. Try that instead. If pain persists, see a medical professional.

For Mo

When to recommend this exercise:

• User wants to develop outer quad sweep (aesthetics)
• User is intermediate/advanced with good knee stability
• User wants to add variety to leg training
• User has mastered standard leg press and wants progression
• User is a bodybuilder targeting specific quad development

Who should NOT do this exercise:

• Beginners (need to master standard stance first)
• Users with knee pain or injury history (ACL, meniscus, patellar issues)
• Users whose knees cave inward on standard stance
• Users with limited ankle mobility
• Users with hip impingement issues

Key coaching cues to emphasize:

1. "Feet hip-width apart, not touching"
2. "Knees track straight ahead — do NOT let them cave inward"
3. "Use 10-20% less weight than standard stance"
4. "Focus on outer quad contraction"

Common issues to watch for in user feedback:

• "My knees cave inward" → Weight too heavy, or narrow stance not suitable for them
• "It feels unstable" → Normal, narrow base is less stable — reduce weight
• "I don't feel it in my quads" → May need to focus on mind-muscle connection
• "My knees hurt" → Stop narrow stance, return to standard or wide stance
• "How narrow should I go?" → Hip-width, NOT narrower

Programming guidance:

• Pair with: Standard leg press (do standard first, then narrow), leg curls, calf raises
• Avoid same day as: Multiple other narrow stance exercises
• Frequency: 1-2x per week (don't overdo narrow stance)
• Load: 10-20% less than standard stance
• Placement: After main compound leg work (squat or standard leg press)

Progression signals:

• Ready to progress when: Can do 3x12 with perfect knee tracking, 1-2 RIR
• Regress if: Knees caving inward, knee pain, excessive instability

Special notes:

• Narrow stance is SUPPLEMENTARY, not essential
• Don't sacrifice knee safety for outer quad development
• Wide stance can also build great quads and is safer for many people
• Genetics play a huge role in quad shape — narrow stance helps but won't transform your structure
• If user has knee valgus tendency (knees cave), this exercise may not be appropriate
• Great for bodybuilders and physique athletes
• Less useful for strength athletes (standard/wide stance is stronger)

Red flags to watch for:

• Knees caving inward despite cueing → STOP, not suitable for this user
• Knee pain during or after → STOP, return to standard stance
• User keeps asking "how narrow can I go?" → Ego issue, educate on hip-width minimum

Alternative recommendations if narrow stance doesn't work:

• Wide stance leg press (also targets quads, safer for many)
• Leg extensions (isolation without stability demands)
• Standard leg press with focus on full ROM
