Movement Summary
🎯 Setup
Starting Position
- Seat adjustment: Align shoulder joint with machine's pivot point
- Your shoulder should match the axis of rotation marked on machine
- Typically marked with a red dot or indicator
- Arm position: Rest upper arms against pads, elbows slightly bent
- Weight selection: Start lighter than you'd use with dumbbells
- Beginner: 10-20 lbs
- Intermediate: 20-40 lbs
- Advanced: 40-70+ lbs
- Posture: Sit tall, chest against pad, core engaged
- Grip: Lightly hold handles (arms do the work, not hands)
Equipment Setup
| Equipment | Setting | Notes |
|---|---|---|
| Seat height | Shoulder aligned with pivot | Critical for proper mechanics |
| Back pad | Snug against chest | Prevents torso movement |
| Weight stack | Conservative start | Machine resistance feels different |
"Sit tall, shoulders aligned with machine pivot, arms relaxed in pads — let the machine guide the path"
🔄 Execution
The Movement
- ⬇️ Lowering
- ⏸️ Bottom Position
- ⬆️ Raising
- 🔝 Top Position
What's happening: Controlled return to start
- Slowly lower pads back to sides
- Maintain constant tension — don't let stack crash
- Stop just short of weights touching (keep tension)
- Breathing: Inhale on the way down
Tempo: 2-3 seconds
Feel: Stretch in side delts, continuous tension
What's happening: Brief reset without full rest
- Arms at sides, pads just above rest position
- Don't let weight stack touch — maintain tension
- No pause or relaxation
- Ready for next rep
Common error here: Bouncing or using momentum from the bottom — stay smooth
What's happening: Pushing pads laterally upward
- Push pads up and out in arc motion
- Drive with elbows, not hands
- Stop at shoulder height (or slightly below)
- Breathing: Exhale as you push
Tempo: 1-2 seconds (smooth and controlled)
Feel: Intense contraction in side delts
What's happening: Peak contraction
- Arms parallel to ground or slightly below
- Brief squeeze (0.5-1 second)
- Maintain chest against back pad
- No shrugging — shoulders stay down
Key: Machine prevents going too high — trust the ROM
Key Cues
- "Push with elbows" — drive the movement from elbows, not hands
- "Shoulders down" — actively depress shoulders to minimize trap involvement
- "Chest to pad" — stay pinned to back support throughout
Tempo Guide
| Goal | Tempo | Example |
|---|---|---|
| Strength | N/A | Not a strength exercise |
| Hypertrophy | 2-1-2-0 | 2s up, 1s pause, 2s down, no pause |
| Pump | 1-0-3-0 | 1s up, no pause, 3s eccentric |
💪 Muscles Worked
Activation Overview
Primary Movers
| Muscle | Action | Activation |
|---|---|---|
| Side Deltoids | Shoulder abduction — raising arms to sides | █████████░ 95% |
Secondary Muscles
| Muscle | Action | Activation |
|---|---|---|
| Front Deltoids | Assist in arm raising | ██░░░░░░░░ 20% |
| Upper Traps | Stabilize shoulder girdle | ███░░░░░░░ 30% |
Stabilizers
| Muscle | Role |
|---|---|
| Forearms | Light grip on handles |
Machine advantage: Fixed path eliminates stabilizer demand, allowing maximum focus on side delts. Less front delt and trap involvement compared to free weights due to optimized movement pattern. To maximize side delt activation: Push through elbows, maintain chest contact with pad, avoid shrugging
🎯 Benefits
Primary Benefits
| Benefit | Explanation |
|---|---|
| Pure side delt isolation | Machine eliminates stabilization, forces direct side delt work |
| Beginner-friendly | Fixed path makes it impossible to cheat or use momentum |
| Consistent tension | Cam system provides optimal resistance curve throughout ROM |
| Joint-friendly | Reduces impingement risk with controlled path |
| Easy to load | Quick weight changes for drop sets and progressive overload |
Training Applications
- Muscle building: Excellent for hypertrophy due to consistent tension
- Mind-muscle connection: Easier to "feel" delts working without stabilization concerns
- Rehab/prehab: Safer reintroduction to shoulder work after injury
- Drop sets: Pin-loaded design perfect for quick weight reductions
- Beginners: Learn lateral raise pattern before progressing to free weights
⚠️ Common Mistakes
| Mistake | What Happens | Why It's Bad | Fix |
|---|---|---|---|
| Seat too high/low | Shoulder doesn't align with pivot | Awkward mechanics, joint stress | Align shoulder with machine pivot point |
| Shrugging shoulders | Elevating shoulder blades | Traps steal work from delts | "Shoulders down" cue, lighter weight |
| Pushing too high | Raising beyond machine's ROM | Fighting the machine, unnecessary | Stop where machine naturally stops |
| Torso lean | Coming off back pad | Recruits other muscles | Stay pinned to back support |
| Gripping too hard | White-knuckling handles | Forearm fatigue, tension away from delts | Loose grip, push with arms |
Poor seat adjustment — if your shoulder isn't aligned with the machine's pivot point, the entire movement feels awkward and can stress your joints. Take 30 seconds to dial in proper positioning before your first set.
Self-Check Checklist
- Shoulder aligned with machine pivot point
- Chest firmly against back pad throughout
- Shoulders staying depressed (not shrugging)
- Pushing with elbows, not pulling with hands
- Smooth tempo, no jerking or bouncing

Progressions (Harder)
| Exercise | When Ready | Link |
|---|---|---|
| Dumbbell Lateral Raise | Want to challenge stabilizers | |
| Cable Lateral Raise | Want adjustable angles | |
| Leaning Lateral Raise | Want increased ROM |
Alternatives (Same Goal, Different Movement)
- Equipment Substitutes
- Compound Alternatives
| Alternative | Equipment | Notes |
|---|---|---|
| Dumbbell Lateral Raise | Dumbbells | More stabilization required |
| Cable Lateral Raise | Cable machine | Constant tension, adjustable |
| Band Lateral Raise | Resistance band | Home/travel option |
| Alternative | Type | Trade-off |
|---|---|---|
| Upright Row | Compound | Works side delts + traps |
| Dumbbell Press | Compound | Less isolation, overall delt work |
🛡️ Safety & Contraindications
Who Should Be Careful
| Condition | Risk | Modification |
|---|---|---|
| Shoulder impingement | Pinching at top of movement | Reduce ROM, stop before discomfort |
| Rotator cuff issues | Strain on stabilizers | Very light weight, controlled tempo |
| AC joint issues | Compression at top | Partial ROM, stop at 45-60° |
- Sharp pain in shoulder joint
- Clicking or popping with pain
- Numbness or tingling down arm
- Pain persists after stopping
Form Safety Tips
| Tip | Why |
|---|---|
| Align shoulder with pivot | Ensures proper mechanics |
| Keep chest against pad | Prevents compensatory movements |
| Don't force ROM | Machine dictates safe path |
| Light grip on handles | Reduces forearm fatigue |
Safe Failure
How to safely stop a set:
- When fatigued: Let pads return to start position smoothly
- If pain occurs: Stop immediately, exit machine carefully
- At failure: Machine prevents dangerous positions — simply stop pushing
Lateral raise machines are one of the safest shoulder exercises. The fixed path prevents dangerous positions, and there's no risk of dropping weight on yourself.
🦴 Joints Involved
| Joint | Action | ROM Required | Stress Level |
|---|---|---|---|
| Shoulder | Abduction | 0-90° | 🟢 Low-Moderate |
| Elbow | Static hold | Slight flexion | 🟢 Very Low |
Mobility Requirements
| Joint | Minimum ROM | Test | If Limited |
|---|---|---|---|
| Shoulder | 90° abduction | Raise arm to side | Machine allows limited ROM safely |
The machine's guided path reduces impingement risk compared to free weights. Most people with mild shoulder issues can tolerate this movement when they can't perform dumbbell lateral raises.
❓ Common Questions
Is the machine version as effective as dumbbells?
For pure side delt hypertrophy, the machine is equally if not more effective due to consistent tension and better isolation. However, dumbbells offer additional benefits like stabilizer engagement and functional carry-over. Use both in your training for best results.
How heavy should I go compared to dumbbell lateral raises?
You can typically handle 2-3x more weight on the machine than with dumbbells due to the stability and leverage advantages. If you use 15 lb dumbbells, expect to use 30-50 lbs on the machine. Let the burn in your delts guide you, not the number on the stack.
Why do I feel it more in my traps than my delts?
Either you're shrugging (elevating your shoulders), the seat is too low, or you're using too much weight. Fix: adjust seat so shoulders align with pivot, actively think "shoulders down," and reduce weight by 20-30%.
Should I do machines or free weights first?
If your goal is hypertrophy, it doesn't matter much. Some prefer starting with the machine when fresh to use heavier loads, others prefer finishing with it for a pump. Experiment and see what works best for you.
Can I use this machine for single-arm work?
Yes! Many machines allow unilateral work. This is excellent for addressing side-to-side imbalances and can create an even stronger mind-muscle connection. Use the same weight for each arm, even if one is weaker.

- "Shoulders down — don't shrug"
Common issues to watch for in user feedback:
- "I don't feel it in my delts" → Check seat height, reduce weight, focus on elbow drive
- "My traps are taking over" → Lower weight, cue shoulder depression, check seat position
- "It feels awkward" → Almost always a seat height issue
Programming guidance:
- Pair with: Overhead pressing, front raises, rear delt work
- Avoid same day as: Not applicable — can train delts frequently
- Typical frequency: 2-3x per week
Progression signals:
- Ready to progress when: Can complete 3x15 with perfect form, strong contraction, wants more challenge
- Progress to: Dumbbell Lateral Raise or Cable Lateral Raise
- Regress if: Shoulder discomfort, can't control the weight, excessive trap involvement
