🎯 Setup

Starting Position

1. Pad position: Key difference — position pad 2-3 inches LOWER than standard back extension
   • Pad should be on upper thighs, NOT at hip crease
   • Lower position increases hip extension ROM
   • Allows hips to move through full range
2. Foot position: Secure feet with specific positioning
   • Toes turned OUT 15-30° (externally rotated)
   • This external rotation pre-activates glutes
   • Feet under ankle pads for stability
3. Spinal position: Intentionally different from standard
   • Maintain slight thoracic rounding (upper back)
   • Think "neutral to slightly rounded" — NOT arched
   • This reduces spinal extensor involvement
4. Starting height: Begin with torso horizontal or slightly above
   • Not hyperextended — just neutral
5. Hand position: Arms crossed over chest or hands behind head
   • Hands behind head can increase difficulty

Equipment Setup

Equipment	Setting	Notes
Back extension bench	Pad positioned LOW — on upper thighs	Critical for glute emphasis
Foot angle	Toes turned out 15-30°	Activates glutes more
Starting height	Torso horizontal	Not extended

Setup Cue

"Pad low on your thighs, toes out, back slightly rounded — we're doing hip extension, not spinal extension"

Why This Setup Works

Standard back extension:

• Pad at hip crease
• Straight spine emphasis
• Mix of hip and spinal extension
• More spinal erector focus

Glute-focused variation:

• Pad on upper thighs → increases hip ROM
• Toes out → pre-activates glutes
• Slight back rounding → minimizes spinal extensors
• Pure hip extension focus → maximizes glute engagement

🔄 Execution

The Movement

🔧 Starting Position

What's happening: Establishing glute-focused position

1. Positioned on bench, pad on upper thighs (below hips)
2. Feet secured, toes turned out 15-30°
3. Torso horizontal, slight upper back rounding maintained
4. Arms crossed over chest
5. Actively squeeze glutes before moving
6. Core lightly engaged

Tempo: Establish perfect position and glute activation

Feel: Glutes engaged even before movement starts

Critical: The pad position and toe angle are key — setup determines which muscles dominate

⬇️ Lowering Phase

What's happening: Pure hip flexion while maintaining spinal position

1. Allow hips to flex — fold at the hip joint
2. Maintain the same spinal position (slight rounding stays constant)
3. Lower torso toward floor via hip flexion only
4. Keep toes pointed out throughout
5. Lower until deep stretch in glutes and hamstrings
6. Typical ROM: 90° or slightly more (torso vertical to past vertical)
7. Breathing: Inhale as you lower

Tempo: 2-3 seconds (controlled descent)

Feel:

• Deep stretch in glutes and hamstrings
• Minimal change in back position
• Movement coming entirely from hips

Key difference from standard: Your back stays in the same rounded position — all movement is hip flexion, not spinal flexion

⏸️ Bottom Position

What's happening: Maximum hip flexion, glutes stretched

1. Torso lowered as far as comfortable (usually past vertical)
2. Deep stretch in glutes
3. Spinal position unchanged from start
4. Pause for 1 second to eliminate momentum
5. Prepare to squeeze glutes

Feel: Glutes and hamstrings under stretch, ready to contract

⬆️ Extension Phase (THE KEY)

What's happening: Aggressive glute contraction to drive hip extension

1. Think "squeeze glutes as hard as possible"
2. Drive hips forward/torso up via glute contraction
3. Actively contract glutes — this is the most important cue
4. Focus on hip extension, not spinal extension
5. Stop at neutral horizontal — do NOT hyperextend
6. Maintain same spinal position throughout
7. Breathing: Exhale forcefully as you squeeze glutes

Tempo: 1-2 seconds with maximum glute contraction

Feel:

• Intense glute contraction (should be primary feeling)
• Hamstrings working secondarily
• Minimal lower back involvement

Critical cues:

• "Squeeze your glutes like you're trying to crack a walnut"
• "Drive your hips forward, not your chest up"
• "Make your glutes do ALL the work"

🔝 Top Position

What's happening: Peak glute contraction at neutral

1. Torso horizontal (neutral alignment)
2. Glutes squeezed MAXIMALLY
3. Do NOT hyperextend — stop at horizontal
4. Pause 1-2 seconds at top with glutes contracted
5. Maintain slight spinal rounding
6. Then lower for next rep

Critical: The pause with peak glute contraction is what makes this variation effective. Don't rush it.

Key Cues

Primary Cues

• "Pad on your thighs, NOT your hips" — setup for success
• "Toes out, squeeze glutes before you even start" — pre-activation
• "Drive your hips forward, back stays the same" — hip extension focus
• "Squeeze glutes like you're crushing something" — maximum contraction
• "Pause and squeeze at the top — hold it" — peak contraction

Tempo Guide

Goal	Tempo	Example
Glute Hypertrophy	3-1-2-2	3s down, 1s pause bottom, 2s up, 2s squeeze top
Activation	2-0-2-3	2s down, no pause, 2s up, 3s squeeze top
Strength-Endurance	2-0-1-1	2s down, no pause, 1s up, 1s squeeze

Note: The pause and squeeze at the top is critical for glute emphasis

💪 Muscles Worked

Activation Overview

Primary Movers

Muscle	Action	Activation
Glutes (Maximus)	Primary hip extension — driving hips forward with maximum contraction	█████████░ 95%

Secondary Muscles

Muscle	Action	Activation
Hamstrings	Assist hip extension	██████░░░░ 60%
Erector Spinae	Maintain spinal position (isometric, reduced role)	████░░░░░░ 40%

Stabilizers

Muscle	Role
Core	Maintains torso position
Lower Back	Supports spine in rounded position

Why Glute Activation Is So High

This variation maximizes glute activation through multiple mechanisms:

1. Pad position on thighs → Increases hip extension ROM from ~20° to ~40°+
2. Toes turned out → External rotation pre-activates gluteus maximus
3. Slight spinal rounding → Reduces spinal erector contribution by ~50%
4. Emphasis on hip extension → Focuses on glute action, not back extension
5. Peak contraction pause → Maximizes glute engagement at top

Comparison:

• Standard back extension: ~60% glute, ~80% erector
• Glute-focused variation: ~95% glute, ~40% erector

This can approach hip thrust levels of glute activation (~100%) while also training spinal stability.

⚠️ Common Mistakes

Mistake	What Happens	Why It's Bad	Fix
Pad positioned too high	At hip crease like standard	Reduces hip ROM, more back extension	Move pad 2-3" lower onto thighs
Hyperextending at top	Arching backward past neutral	Recruits spinal extensors, reduces glute focus	Stop at horizontal, focus on glute squeeze
Not squeezing glutes	Passive rising using back	Misses the point — back does work instead of glutes	Actively contract glutes, pause at top
Feet straight forward	Neutral toe position	Less glute activation	Turn toes out 15-30°
Too fast, no pause	Rushing through reps	No peak contraction, less glute work	Slow down, pause 1-2s at top with squeeze

Most Common Error

Not actively squeezing glutes at the top. This variation only works if you CONSCIOUSLY contract your glutes hard. If you just passively rise up, your back will do the work. The mental focus on glute contraction is what makes this effective.

Self-Check Checklist

• Pad is on upper thighs, NOT at hip crease
• Toes are turned out 15-30 degrees
• I stop at neutral horizontal, NOT hyperextended
• I actively squeeze glutes as hard as possible on every rep
• I pause 1-2 seconds at top with glutes contracted
• I feel this primarily in glutes, NOT lower back

📊 Programming

Rep Ranges by Goal

Goal	Sets	Reps	Rest	Load	RIR
Activation	2-3	15-20	60s	Bodyweight	4-5
Hypertrophy	3-4	15-20	60-90s	Bodyweight to light weight	1-2
Strength-Endurance	3-4	20-30+	60s	Bodyweight	1-2

Workout Placement

Program Type	Placement	Rationale
Lower body day	Early-middle	Glute pre-activation before squats/deadlifts
Lower body day	Late	Glute finisher after main lifts
Glute focus day	Middle	Core glute hypertrophy work
Warm-up	First	2x15-20 for glute activation

Programming Applications

As Activation (before main lifts):

• 2 sets x 15-20 reps, bodyweight
• Focus on glute squeeze and activation
• Primes glutes for squats, deadlifts, lunges

As Hypertrophy Work (middle of workout):

• 3-4 sets x 15-20 reps
• Can add light weight
• Focus on peak contraction

As Finisher (end of workout):

• 2-3 sets to failure (20-30+ reps)
• Bodyweight, high reps
• Glute burnout

Frequency

Training Level	Frequency	Volume Per Session
Beginner	2-3x/week	2-3 sets
Intermediate	3-4x/week	3-4 sets
Advanced	3-5x/week	Varies — can use daily for activation

Note: Because this is bodyweight or lightly loaded, it's low-fatigue and can be done frequently

Progression Scheme

Progressive Overload

For glute-focused variations, quality > quantity.

Progress in this order:

1. Perfect the glute squeeze — ensure you feel 95% of work in glutes
2. Add pause time — 1s → 2s → 3s pause at top
3. Add reps — build to 3x20+
4. Add light weight — 10 lbs, 25 lbs, etc.
5. Use bands — for peak contraction emphasis

Most people never need more than 25-45 lbs added weight. The glute contraction is what matters.

🛡️ Safety & Contraindications

Who Should Be Careful

Condition	Risk	Modification
Disc issues	Spinal flexion under light load	Get medical clearance, may be OK with light load
Low back pain (acute)	Movement may aggravate	Wait until cleared, try glute bridges instead
Pregnancy	Prone position uncomfortable	Avoid after first trimester
Extreme spinal flexion intolerance	Slight rounding may be problematic	Use hip thrust instead

Stop Immediately If

• Sharp pain in lower back
• Shooting pain down legs
• Cramping in lower back or glutes beyond normal muscle fatigue
• Dizziness

Injury Prevention

Strategy	Implementation
Don't hyperextend	Stop at neutral horizontal, never arch past
Start bodyweight	Master the pattern before adding load
Focus on glutes	If lower back hurts, check form — glutes should do the work
Control the eccentric	Slow lowering prevents excessive spinal flexion
Progress gradually	Build to high reps before adding weight

Spinal Safety

Key points:

• The slight spinal rounding is intentional but should be controlled and minimal
• This is NOT extreme flexion — just neutral to slightly rounded upper back
• The load is minimal (bodyweight or light external weight)
• If you have disc issues: The slight flexion may be problematic — consult medical professional

Important distinction:

• Dangerous: Heavy spinal flexion under load (like a rounded deadlift)
• Generally safe: Light spinal flexion with minimal load (this exercise) for healthy individuals
• Context matters: If you have back issues, get clearance

Spinal Position Philosophy

Some strength coaches avoid any spinal flexion. Others (like Bret Contreras) advocate for slight rounding in glute-focused back extensions specifically to reduce spinal extensor involvement and maximize glute activation.

Best approach: If you have healthy spine and no history of issues, this is safe. If you have concerns, use hip thrusts instead for pure glute work with zero spinal flexion.

🦴 Joints Involved

Joint	Action	ROM Required	Stress Level
Hip	Flexion/Extension	40-50° extension (larger ROM than standard)	🟡 Moderate
Spine	Maintained in slight flexion (not moving)	Minimal — stays constant	🟢 Low

Mobility Requirements

Joint	Minimum ROM	Test	If Limited
Hip	Full extension, good flexion	Can extend hips fully and fold forward	Hip flexor stretches, mobility work
Hamstrings	Adequate length	Can fold forward with slight knee bend	Daily stretching

Joint Health Note

This variation is very joint-friendly:

• Hip: Full hip extension ROM is excellent for hip health
• Spine: Minimal spinal movement (isometric position)
• Low overall stress — bodyweight or light loading
• Great for: Building hip extension capacity and glute strength without heavy loading

Excellent for both beginners learning glute activation and advanced lifters wanting high-rep glute work.

❓ Common Questions

How is this different from a regular back extension?

Four key differences:

1. Pad position: Lower on thighs (not at hip crease) → increases hip extension ROM
2. Toe angle: Turned out 15-30° (not straight) → activates glutes more
3. Spinal position: Slight rounding maintained (not arched/neutral) → reduces spinal extensor involvement
4. Focus and cueing: Active glute squeeze with pause (not passive rising) → maximizes glute contraction

Result: ~95% glute activation vs ~60% in standard back extension

Is it safe to round my back?

In this specific context, yes — with caveats:

• The rounding is SLIGHT — not extreme flexion
• The load is MINIMAL — bodyweight or light weight
• It's controlled — intentional position, not collapsing
• Purpose: Reduces spinal extensor contribution so glutes do more work

If you have disc issues or back problems: Check with a medical professional first. You may be better off with hip thrusts (zero spinal flexion).

For healthy individuals: This is generally safe and effective.

I don't feel this in my glutes, I feel it in my back. What's wrong?

Common causes and fixes:

1. Pad too high → Move it lower onto thighs
2. Not squeezing glutes → Actively contract glutes at top, pause 2 seconds
3. Hyperextending → Stop at horizontal, don't arch backward
4. Toes not out → Turn toes out 15-30 degrees
5. Going too fast → Slow down, focus on glute contraction
6. Mind-muscle connection → May need practice — think "squeeze glutes" entire rep

Try: 2 sets of 10 VERY slow reps, pausing 3 seconds at top with maximum glute squeeze. Focus entirely on feeling glutes.

Should I feel my hamstrings?

Yes, but glutes should dominate.

You'll feel:

• Primary (80%+): Glutes contracting and under stretch
• Secondary (20%): Hamstrings assisting

If hamstrings are doing most of the work:

• Check pad position (should be low on thighs)
• Focus on glute squeeze, not just rising up
• Turn toes out more

When should I add weight?

Only after mastering the bodyweight version:

Signs you're ready:

• Can do 3 sets of 20+ reps
• Feel it 90%+ in glutes every rep
• Can pause 2 seconds at top with max contraction
• Perfect form throughout

Then add: 10 lbs to start, build back to 3x15-20 before adding more

Note: Many people make great progress with just bodyweight by focusing on contraction quality and pause duration. Weight is optional.

Can I do this every day?

Yes — it's low-fatigue and great for frequent use.

Daily applications:

• As activation: 2x15 before lower body workouts
• As GPP/work capacity: 3x20 several times per week
• As hypertrophy work: 3-4x per week with full effort

Because it's bodyweight or lightly loaded, recovery demands are minimal. Many people do this 5-7x per week as part of warm-ups.

Hip thrust vs glute-focused back extension — which is better?

Both are excellent — use both:

Hip Thrust:

• Can load MUCH heavier
• Pure hip extension, zero spinal flexion
• Better for maximal strength
• Requires more setup (bench, barbell, pad)

Glute-Focused Back Extension:

• Bodyweight or light loading
• Simple setup, minimal equipment
• Excellent for high reps and activation
• Some spinal stability component
• Great for warm-ups and finishers

Best approach: Hip thrusts for heavy glute strength, glute-focused back extensions for activation, high-rep work, and finishers.

For Mo

When to recommend this exercise:

• User wants to build glute strength and size
• User wants glute activation work for warm-ups
• User has access to back extension bench
• User wants high-rep glute work without heavy loading
• User prefers glute focus over full posterior chain work

Who should NOT do this exercise:

• Acute low back injury → Suggest glute bridge or wait for clearance
• Severe disc issues without medical approval → Hip thrust is safer (no flexion)
• Spinal flexion intolerance → Use hip thrust instead
• Pregnancy (after first trimester) → Prone position uncomfortable

Key coaching cues to emphasize:

1. "Move the pad down 2-3 inches onto your thighs — this is critical"
2. "Turn your toes out like a duck — 15-30 degrees"
3. "Squeeze your glutes as hard as you can at the top and HOLD for 2 seconds"
4. "Stop at flat/horizontal — don't arch backward"
5. "You should feel this 90% in your glutes, NOT your back"

Common issues to watch for in user feedback:

• "I feel it all in my back" → Check pad position, cue glute squeeze harder, check toe angle
• "I'm not sure if I'm doing it right" → Start with slow reps, 3s pause at top, focus on feeling glutes
• "Should my back be rounded?" → Yes, slightly — it's intentional to reduce back involvement
• "How much weight should I use?" → Master bodyweight first, then only 10-25 lbs

Programming guidance:

• As activation: 2x15-20 before squats/deadlifts
• As hypertrophy: 3-4x15-20 mid-workout
• As finisher: 2-3 sets to failure (25-30+)
• Pair with: Hip thrusts, squats, lunges
• Frequency: Can do daily if used for activation

Progression signals:

• Ready to progress when: 3x20 with perfect glute squeeze, feel it 90%+ in glutes
• Regress if: Feeling it mostly in back — check all setup parameters
• Next step: Add 10 lbs or increase pause time to 3-5s

Red flags:

• Feeling it all in lower back → setup is wrong or not squeezing glutes
• Sharp back pain → stop immediately, check form or rest
• Hyperextending past neutral → injury risk, cue to stop at horizontal
• Can't feel glutes at all → may need practice with glute bridges first to learn glute activation
