Movement Summary
🎯 Setup
Starting Position
- Bench position: Lie flat with full back contact
- Starting arm position: Arms extended overhead at ~100-110° angle (slight lean back from vertical)
- Grip: Neutral grip (palms facing each other) with dumbbells
- Elbow position: Keep elbows relatively close together
- Foot placement: Feet flat on floor for stability
Equipment Setup
| Equipment | Setting | Notes |
|---|---|---|
| Dumbbells | Moderate weight | Lighter than standard tricep work |
| Alternative | EZ-bar or straight bar | Can use instead of dumbbells |
| Bench | Flat | Full back support |
"Start like a skull crusher, but arms angled back slightly — you'll roll even further back before extending"
🔄 Execution
The Movement
- 🔄 Rollback Phase
- ⬇️ Lowering
- ⬆️ Extending
- 🔝 Return Phase
What's happening: Arms roll back behind head while staying extended
- From overhead position, roll straight arms back
- Keep elbows locked (arms stay straight)
- Go back until dumbbells are behind/beside your head
- Feel stretch in lats and long head of triceps
- This increases range of motion vs standard skull crusher
Tempo: 1-2 seconds
Feel: Stretch in triceps long head, lat engagement
What's happening: Bend elbows to bring weight toward head
- From rolled-back position, bend at elbows only
- Lower dumbbells toward temples/forehead
- Keep upper arms stationary (don't roll forward yet)
- Elbows stay pointing up, not flaring out
- Control the descent
Tempo: 2-3 seconds
Feel: Deep stretch in triceps, especially long head
What's happening: Extend elbows to straighten arms
- Drive dumbbells back up by extending elbows
- Focus on tricep contraction
- Return to the rolled-back position (arms straight behind head)
- Keep upper arms in same position
Tempo: 1-2 seconds
Feel: Intense tricep contraction, especially long head
What's happening: Roll arms forward to starting position
- With arms straight, roll forward to overhead position
- Return to ~100-110° angle
- This completes one rep
- Can go straight into next rollback, or pause briefly
Key Cues
- "Roll back, then crush, then extend, then roll forward" — the four phases
- "Upper arms move separately from forearms" — distinct rollback vs. elbow bend
- "Elbows stay narrow" — don't let them flare out
Tempo Guide
| Goal | Tempo | Example |

| Strength | 2-0-1-0 | 2s down, no pause, 1s up, no pause |
| Hypertrophy | 3-1-2-1 | 3s down, 1s pause, 2s up, 1s pause at rollback |
| Stretch Focus | 4-2-2-0 | 4s down, 2s pause stretched, 2s up |
💪 Muscles Worked
Activation Overview
Primary Movers
| Muscle | Action | Activation |
|---|---|---|
| Triceps - Long Head | Elbow extension from stretched position | █████████░ 90% |
Secondary Muscles
| Muscle | Action | Activation |
|---|---|---|
| Triceps - Lateral Head | Assists elbow extension | ███████░░░ 70% |
| Triceps - Medial Head | Assists elbow extension | ██████░░░░ 60% |
| Anterior Deltoid | Shoulder stabilization | ████░░░░░░ 40% |
Stabilizers
| Muscle | Role |
|---|---|
| Lats | Control rollback phase, arm position |
| Rotator Cuff | Stabilize shoulder through ROM |
| Core | Prevent arching during rollback |
Long head specialization: The rollback phase puts the long head on maximum stretch since it crosses both the shoulder and elbow joints. This makes it superior to standard skull crushers for long head development.
⚠️ Common Mistakes
| Mistake | What Happens | Why It's Bad | Fix |
|---|---|---|---|
| Skipping rollback | Becomes standard skull crusher | Defeats purpose, less long head stretch | Emphasize the rollback phase |
| Flaring elbows | Elbows move outward | Less tricep focus, elbow strain | Keep elbows pointing up |
| Rolling shoulders up | Shoulders come off bench | Lose stability, neck strain | Keep shoulders down and back |
| Too much weight | Can't control rollback | Dangerous, lose form | Use 20-30% less than skull crushers |
| Not extending fully | Partial reps at top | Less tricep contraction | Lock out completely |
Rushing through the rollback — many people skip or minimize the rollback phase because it feels awkward. The rollback is what makes this exercise special. Take time to roll arms back fully before bending elbows.
Self-Check Checklist
- Arms roll back behind head before bending
- Elbows stay close together (not flared)
- Full extension at the rollback position
- Controlled tempo on all phases
- Shoulders stay on bench

🛡️ Safety & Contraindications
Who Should Be Careful
| Condition | Risk | Modification |
|---|---|---|
| Elbow tendonitis | Pain during extension | Reduce ROM, use lighter weight |
| Shoulder impingement | Pain during rollback | Reduce rollback ROM |
| Lower back issues | May arch during rollback | Engage core, reduce weight |
| Wrist pain | Strain holding dumbbells | Use EZ-bar instead |
- Sharp elbow pain (not muscle fatigue)
- Shoulder popping or clicking with pain
- Loss of control during rollback
- Lower back pain or excessive arching
Safety Guidelines
| Aspect | Guideline |
|---|---|
| Weight selection | Start 20-30% lighter than skull crushers |
| Spotter | Helpful when learning the movement |
| Warm-up | Light overhead and extension work first |
| Control | Never rush the rollback phase |
Safe Failure
How to safely fail:
- From rollback position: Roll forward to overhead
- Lower dumbbells to chest — controlled descent
- Sit up with dumbbells — bring to lap
- Do not drop behind head — dangerous
The rollback phase can cause lower back arching if core isn't engaged. Keep abs braced throughout, especially during the rollback. If you find yourself arching excessively, reduce the weight.
🦴 Joints Involved
| Joint | Action | ROM Required | Stress Level |
|---|---|---|---|
| Elbow | Flexion/Extension | ~0-150° | 🟡 Moderate |
| Shoulder | Flexion, arm rollback | Overhead to hyperextension | 🟡 Moderate |
| Wrist | Neutral grip stability | Minimal | 🟢 Low |
Mobility Requirements
| Joint | Minimum ROM | Test | If Limited |
|---|---|---|---|
| Shoulder | Overhead mobility | Can raise arms overhead comfortably | Reduce rollback depth |
| Elbow | Full flexion/extension | Can touch shoulder, fully straighten | Work on mobility first |
| Thoracic | Extension | Rollback without lower back arch | Core work, reduce ROM |
The rollback phase requires good shoulder mobility and extension. If you lack this mobility, you'll compensate with lower back arching, which is risky. Build the mobility first or stick to standard skull crushers.
❓ Common Questions
How is this different from a skull crusher?
The rolling tricep extension adds a rollback phase where you roll your straight arms back behind your head before bending at the elbows. This increases the stretch on the triceps long head significantly compared to a standard skull crusher where arms stay more vertical.
Should I use dumbbells or a barbell?
Both work. Dumbbells allow independent arm movement and may be easier on wrists. EZ-bar is often preferred as it's easier to control during the rollback and gentler on wrists than a straight bar. Start with dumbbells to learn the pattern.
How far back should I roll my arms?
Until you feel a good stretch in your lats and long head of triceps — usually when dumbbells are beside or slightly behind your head. Don't force excessive ROM if it causes shoulder discomfort or makes you arch your back.
Why does my lower back arch during this?
You're likely not engaging your core, or you're rolling back too far. Brace your abs before each rep and reduce the rollback ROM. Your lower back should stay flat on the bench throughout.
Can I do this standing?
Yes, that would be a French Press — a standing overhead extension. It works similarly but requires more core stability and coordination. The lying version allows for better isolation and heavier loading.
