Movement Summary


🎯 Setup

Starting Position

  1. Dumbbell selection: Choose moderate weight (start lighter than expected)
  2. Grip setup:
    • Cup your hands under the TOP weight plate of dumbbell
    • Palms facing up, supporting the weight
    • Thumbs and index fingers form a diamond/triangle shape
    • Bottom weight plate hangs down
  3. Get dumbbell overhead:
    • Option A (lighter weights): Start with DB on thighs, press directly overhead
    • Option B (heavier weights): Rest DB on thigh, use knee to help lift to shoulder, then press overhead
    • Never try to curl heavy DB directly from floor to overhead
  4. Body position - Standing:
    • Feet hip-width apart
    • Slight stagger optional for stability
    • Knees soft (slight bend)
    • Core braced maximally
    • Slight forward lean from hips (5-10°)
  5. Body position - Seated (recommended for heavy weights):
    • Sit on bench with back support (if available)
    • Or sit on end of bench, torso upright
    • Feet flat on floor, wide base
    • Core braced hard
  6. Arm position:
    • Dumbbell overhead, both arms supporting it
    • Elbows pointed forward (not flared out)
    • Upper arms close to ears
    • Start with elbows bent, DB behind/above head

Bench heightFeet flat on floor when seatedProper leg drive and stability

Grip Techniques

How to grip:

  • Both palms face up under top plate
  • Thumbs and index fingers touch, forming diamond shape
  • Remaining fingers wrap around the handle

Benefits:

  • Secure grip on heavy weights
  • Natural hand position
  • Both arms equally involved

Best for: Most people, standard approach

Setup Cue

"Diamond grip under the top plate, press overhead, elbows by your ears — you're about to stretch those triceps deep"

Getting Heavy Dumbbells Into Position Safely

Light dumbbells (15-30 lbs):

  1. Pick up DB with diamond grip
  2. Rest on thigh briefly
  3. Press directly overhead
  4. Lower elbows to start position

Heavy dumbbells (35+ lbs):

  1. Place DB vertical on thigh (top plate up)
  2. Grip it in diamond position
  3. Use knee drive to help lift DB to shoulder height
  4. Press overhead with both arms
  5. Lower elbows to starting position

After set completion:

  1. Extend arms fully overhead
  2. Carefully lower DB to shoulder
  3. Then to lap
  4. NEVER drop a dumbbell from overhead — injury risk
Dumbbell Safety

Never try to curl a heavy dumbbell from the floor directly overhead. Use your legs and progressive stages (floor → thigh → shoulder → overhead). Dropping a dumbbell from overhead can cause serious injury.


🔄 Execution

The Movement

What's happening: Dumbbell overhead, elbows bent, maximum long head stretch

  1. Dumbbell overhead, both hands supporting top plate
  2. Elbows bent to 90-110°, pointing straight forward
  3. Upper arms vertical, close to ears
  4. DB is behind/above head, not in front
  5. Core maximally braced
  6. Standing or seated, stable base
  7. Breathing: Deep breath in, brace core

Cue: "Feel the deep stretch in your triceps — especially the inner/lower part of your arm"

Key point: This stretched overhead position is why the long head gets maximum activation

Common error: Elbows flaring out to sides — keep them narrow, pointed forward

Key Cues

Primary Cues
  • "Diamond grip secure, both hands supporting equally"
  • "Upper arms welded by your ears — they don't move"
  • "Elbows stay pointing forward, not out to the sides"
  • "Drive straight up to the ceiling"
  • "Feel the deep stretch at bottom — that's your long head"
  • "Control it down slowly — fight the weight back"
  • "Core braced like you're about to be punched"

Range of Motion Considerations

Bottom position (stretched):

  • Goal: Maximum safe stretch without shoulder/elbow pain
  • Typical range: 90-110° elbow flexion
  • Individual variation: Some go deeper, some can't
  • Stop before: Dumbbell hits head/neck, or shoulder pain occurs
  • Should feel: Deep tricep stretch, especially inner arm

Top position (lockout):

  • Goal: Complete elbow extension
  • Arms fully straight overhead
  • Dumbbell overhead or slightly behind head (not in front)
  • Don't hyperextend elbows — just straight
ROM & Shoulder Mobility

If you have limited shoulder mobility, you may not achieve a super deep stretch without discomfort. This is OKAY. Go as deep as comfortable. The exercise still works. Separately improve shoulder mobility if needed.

Upper Back (traps, rhomboids)Scapular stability, postureModerate — maintain upright position
LatsStabilize shoulder joint, prevent flaringLow-Moderate — minor postural role

Why Overhead Position Maximizes Long Head

The Anatomical Advantage:

The triceps long head is unique because it crosses TWO joints:

  1. Elbow joint — extends the elbow (like all tricep heads)
  2. Shoulder joint — extends the shoulder (only the long head does this)

Overhead = Maximum Long Head Activation:

  • Overhead position puts shoulder in FLEXION (arm above head)
  • This maximally pre-stretches the long head
  • Stretched muscle produces more force (length-tension relationship)
  • EMG studies show 25-40% MORE long head activation overhead vs. arms-at-side

Visual Result:

  • Mass on inner/lower portion of upper arm
  • Thickness when arm viewed from behind
  • "Meaty" look to the bottom of the arm
  • Essential for complete tricep development

Scientific support:

  • Long head contributes 2/3 of total tricep mass
  • Overhead work required for proportional development
  • Arms-at-side exercises under-develop long head

Head-Specific Emphasis & Development

Activation with overhead DB: 95% — near-maximal

Why maximum activation:

  • Overhead shoulder flexion creates maximum pre-stretch
  • Long head works during both shoulder AND elbow extension
  • Loaded stretch at bottom position = optimal stimulus
  • Free weight demands more stabilization than cables

Visual development:

  • Inner/lower arm mass
  • Thickness from rear view
  • "Full" arm appearance
  • Critical for arm size

Training notes:

  • This exercise is THE long head specialist
  • Essential for balanced tricep development
  • Can't be replicated with pushdowns alone

Practical impact:

  • Adds 1-2" to arm measurement when developed
  • Creates depth/dimension to arm
  • Visible difference in photos from behind

Why This Exercise is Essential

You cannot fully develop your triceps without overhead work. If you only do pushdowns and pressing, your long head will be significantly under-developed compared to lateral/medial heads. This creates:

  • Imbalanced arm appearance
  • Lack of inner arm mass
  • Thinner arms from behind
  • Missing 1-2" of potential arm size

Solution: Include overhead extensions 1-2x per week for complete development.

Free Weight vs. Cable Overhead Extensions

Dumbbell advantages:

  • Can train anywhere (home, hotel, outdoors)
  • Single piece of equipment needed
  • Requires more stabilization = more muscle recruitment
  • Natural movement path (not restricted by cable)
  • Builds functional strength

Cable advantages:

  • Constant tension throughout ROM
  • Easier to control
  • Less risk of dropping weight
  • Smoother resistance curve
  • Slightly easier to learn

Both are excellent — choose based on equipment access and preference.

Standing with heavy DBUnstable base, lower back stressCompensation patterns, injury riskSit on bench for heavy weights
No forward lean when standingTorso too uprightExcessive lower back stressLean forward 5-10° from hips
Most Common Error

Elbows flaring out to the sides — when your upper arms drift outward (away from your ears/head), you dramatically reduce long head activation. The exercise becomes a general tricep movement instead of a long head specialist.

Quick check: Your upper arms should stay close enough to your ears that they almost touch. Film yourself from the front or side to verify elbow position.

Self-Check Checklist

Run through this before and during every set:

  • Diamond grip secure, both hands equally supporting DB
  • Upper arms stay pinned by ears throughout (don't drift forward/back/out)
  • Elbows pointing straight forward (not flared to sides)
  • Achieving full deep stretch at bottom (90-110° elbow flexion)
  • Achieving complete lockout at top (arms fully straight)
  • Controlling eccentric for 2-3+ seconds (fighting the weight down)
  • Core maximally braced (no excessive lower back arch)
  • Stable base — standing with slight lean OR seated firmly
  • Feeling it primarily in triceps, especially inner/lower arm
  • Not hitting head/neck with dumbbell at any point

Form Degradation Warning Signs

Stop the set immediately or reduce weight when you notice:

  1. Elbows starting to flare outward — primary indicator of fatigue
  2. Upper arms moving forward/back — losing isolation
  3. Lower back arching excessively — core fatigue, injury risk
  4. Partial ROM developing — can't get full stretch or lockout anymore
  5. Dumbbell dropping/slamming down — lost eccentric control
  6. Grip shifting or feeling insecure — safety issue
  7. Balance issues — wobbling if standing
  8. Shoulders burning more than triceps — form has broken down
  9. Dumbbell drifting forward significantly — stabilization failure
  10. Any sharp pain in elbow, shoulder, or lower back

Appropriate action: End the set, rest 3-5 minutes, reduce weight 10-20%, retry with perfect form.

Shoulder Mobility Limitations

Signs you have limited shoulder mobility:

  • Pain (not muscle burn) when achieving overhead position
  • Can't comfortably get elbows by ears
  • Shoulder "pinching" or "jamming" sensation
  • Can't get a deep stretch without shoulder discomfort

Solutions if mobility-limited:

  1. Work within pain-free range — don't force ROM that hurts
  2. Focus on contraction — partial ROM still builds muscle
  3. Improve mobility separately:
    • Shoulder dislocations with band/PVC
    • Doorway pec stretches
    • Thoracic spine mobility work
    • Wall slides for overhead position
  4. Try cable version — may allow better positioning
  5. Switch to pushdowns temporarily — build strength while improving mobility

Important: Never force painful ROM. Shoulder pain is a red flag, not something to push through.

Load Selection

Start conservatively — overhead DB extensions are humbling:

  • Beginners: 15-25 lbs
  • Intermediate: 30-45 lbs
  • Advanced: 50-70 lbs
  • Very advanced: 75+ lbs

Most people use 30-50% LESS than their pushdown weight. This is normal due to overhead mechanics, longer ROM, and stabilization demands.

Workout Placement

Program TypeWhen to IncludeRationaleExample Sequence
Push DayAfter compound pressing + pushdownsLong head finisher after main tricep workBench → OHP → Pushdowns → Overhead DB Extension
Arm DaySecond or third tricep exerciseBuild complete triceps after compoundDips → Pushdowns → Overhead DB Extension → Curls
Upper BodyMid-to-late workoutAfter heavy compounds, before smaller accessoriesRows → Bench → Overhead DB Extension → Lateral Raises
Full BodyOptional tricep accessoryIf time/energy allowsSquats → Bench → Rows → Overhead DB Extension
Home WorkoutPrimary tricep exerciseWhen DB is only equipmentPush-ups → Overhead DB Extension → DB Rows

Placement principles:

  • Never first — requires warmed triceps and shoulders
  • After pushdowns ideal — pushdowns pre-fatigue, overhead finishes long head
  • Before small accessories — prioritize bigger movements first
  • Late enough that you're warm, early enough that you have energy

Weekly Frequency Guidelines

Training LevelFrequencyVolume Per SessionWeekly Total Overhead SetsNotes
Beginner1-2x/week2-3 sets3-6 setsFocus on learning movement
Intermediate2x/week3-4 sets6-8 setsStandard balanced development
Advanced2-3x/week3-4 sets8-12 setsVary intensity across sessions

Important context:

  • This is volume for OVERHEAD work specifically
  • Total tricep volume should be 10-20 weekly sets (all exercises combined)
  • Don't exceed 12 sets per week of overhead work (risk of elbow overuse)

Sample weekly split:

  • Session 1 (Monday — Heavy): 3 sets × 8-10 reps, 45 lb DB
  • Session 2 (Thursday — Moderate): 4 sets × 12-15 reps, 30 lb DB, slow tempo

Progression Schemes

Best for: Beginners to early intermediates

Typical progression rate:

  • Beginners: +5 lbs every 2-3 weeks
  • Intermediates: +5 lbs every 3-4 weeks
  • Advanced: +5 lbs every 4-6 weeks

Example:

  • Week 1-2: 3 × 12 at 25 lbs
  • Week 3-4: 3 × 12 at 30 lbs
  • Week 5-6: 3 × 12 at 35 lbs

Pairing & Superset Strategies

Agonist/Antagonist (Opposing Muscles):

  • Overhead DB extension + Dumbbell bicep curl
  • Classic arm superset
  • 10-15 reps each, minimal rest between
  • 60-90s rest between supersets
  • Huge arm pump, time-efficient

Compound Sets (Same Muscle):

  • Pushdowns + Overhead DB extension
  • Pushdowns emphasize lateral head, overhead hits long head
  • No rest between exercises
  • Complete tricep destruction
  • 2-3 compound sets

Tri-Set (Three Exercises):

  • Pushdowns → Overhead DB extension → Diamond push-ups
  • Decreasing load, increasing fatigue
  • No rest between exercises
  • Advanced finisher technique

Pre-Exhaust:

  • Overhead DB extension → Close grip bench press
  • Fatigue triceps in isolation first
  • Then test them in compound movement
  • Advanced technique

Post-Exhaust (Most Common):

  • Close grip bench → Overhead DB extension
  • Heavy compound first for strength
  • Isolation to finish long head
  • Recommended approach for most

Equipment Substitutions

No dumbbell available?

  1. Resistance band over door anchor or secured underfoot
  2. Cable machine overhead extension (very similar)
  3. Water jug/backpack filled with weight (get creative)
  4. Barbell overhead extension (need bench)

Dumbbell increments too large?

  • Use adjustable dumbbells or loadable DB handles
  • Microplates (1.25 lb plates) to add small increments
  • Resistance bands around DB for progressive resistance

Can't hold heavy DB in diamond grip?

  • Use two separate dumbbells (one per hand)
  • Try Fat Gripz or towel around handle for better grip
  • Build grip strength separately

No bench for seated variation?

  • Use sturdy chair with back support
  • Sit on stability ball (advanced, more core work)
  • Stand with split stance and forward lean

🛡️ Safety & Contraindications

Who Should Be Careful

ConditionRisk LevelSpecific RiskRecommended Modification
Elbow tendinitis (tricep tendon)🔴 HighDirect stress on inflamed tendonReduce weight 50%, switch to pushdowns, or rest completely
Shoulder impingement🟡 Moderate-HighOverhead position can aggravateReduce ROM, improve mobility, may need different exercise
Limited shoulder mobility🟡 ModerateCan't achieve comfortable overhead positionWork within pain-free range, improve mobility separately
Lower back issues🟡 ModerateStanding variation stresses lower backUse seated variation (eliminates back stress)
Recent shoulder surgery🔴 HighOverhead loading may compromise healingGet physician clearance first, likely avoid for 3-6+ months
Wrist instability🟢 Low-ModerateHolding DB overhead requires wrist stabilityUse wrist wraps, lighter weight, or switch to cable
Previous elbow injury🟡 ModerateRe-injury risk under loadStart very light (10-15 lbs), ultra-gradual progression
Stop Immediately If
  • Sharp pain in elbow (especially near tricep tendon attachment)
  • Shoulder pain or pinching sensation overhead
  • Feeling like you'll drop the dumbbell (grip failure)
  • Sudden "pop" or "snap" in elbow, shoulder, or tricep
  • Lower back pain (sharp, not muscle fatigue)
  • Numbness or tingling in hands or arms
  • Dumbbell hits head/neck — losing control
  • Dizziness from overhead position — blood pressure issue

Dumbbell-Specific Safety Concerns

Risk: Dropping dumbbell on head/neck

Prevention:

  • Start conservatively light
  • Always maintain secure diamond grip
  • Control the weight — never let it drop
  • Stop set if grip feels compromised
  • Never train to absolute failure on this exercise
  • Use spotter for max attempts

If you feel dumbbell slipping:

  1. Extend arms fully overhead immediately
  2. Carefully lower DB to shoulder
  3. Set on lap
  4. Never try to "save" a dropping rep

Risk: Hitting head/neck with dumbbell

Prevention:

  • Control descent — minimum 2 second eccentric
  • Stop before DB contacts head/neck
  • Learn safe ROM for your build
  • Stand/sit in clear space (not under low ceiling)

Proper bailout:

  • If losing control: extend overhead immediately
  • Carefully lower to shoulder, then lap
  • Don't panic-release the DB

Form Degradation Warning Signs

Watch for these red flags — they indicate you need to stop or reduce weight immediately:

  1. Grip shifting or feeling insecure — safety critical
  2. Elbows flaring progressively outward — fatigue indicator
  3. Upper arms drifting forward/back — losing isolation
  4. Lower back arching excessively (standing) — core fatigue
  5. ROM decreasing — can't get full stretch or lockout
  6. Dumbbell drifting forward significantly — stabilization failure
  7. Balance issues (if standing) — core/stability fatigue
  8. Speed of descent increasing — losing eccentric control
  9. Shoulders burning more than triceps — form breakdown
  10. Any sharp pain (vs. muscle burn) — potential injury

Appropriate response: End the set, rest 3-5 minutes, reduce weight 15-25%, retry with strict form.

Spotter Guidelines

When you need a spotter:

  • Working with weights at 80%+ of your max
  • Going to failure or near-failure
  • Testing new max weight
  • New to the exercise
  • Recovering from injury

How to spot overhead DB extension:

  • Spotter stands behind person performing exercise
  • Hands ready near elbows to assist if needed
  • Assist at elbows, not the dumbbell — push up on forearms
  • Only help as much as needed — minimal assistance
  • Be ready to grab DB if it's dropping

Solo training safety:

  • Always leave 1-2 reps in reserve (RIR)
  • Never train to absolute failure alone
  • Start conservative, progress slowly
  • Clear space around you

Safe Failure Protocol

If you can't complete a rep:

DO:

  1. Extend arms fully overhead (easiest position to hold)
  2. Carefully lower DB to shoulder level
  3. Rest DB on thigh/lap
  4. Take a breath, assess

DON'T:

  • Panic and release the DB
  • Try to force through with terrible form
  • Drop or throw the DB

Recovery Protocols

If experiencing elbow discomfort:

Immediate (Day of):

  • Stop exercise immediately
  • Ice elbow for 15-20 minutes
  • Take anti-inflammatory if appropriate for you
  • Avoid all tricep exercises for 24-48 hours

Short-term (Days 2-5):

  • Assess pain level when moving arm normally
  • If improved significantly: Resume training at 50% weight
  • If not improved: Continue rest, ice 2x daily
  • Consider switching to pushdowns (less elbow stress)

Medium-term (Week 2+):

  • If still painful after 5-7 days: See healthcare provider
  • May need 1-3 weeks complete rest from overhead work
  • Address potential causes:
    • Too much weight?
    • Too much volume?
    • Form breakdown (elbows flaring)?
    • Inadequate recovery between sessions?

Return to training:

  • Start at 40-50% of previous working weight
  • Perfect form only — zero compromises
  • Add weight VERY gradually (2.5-5 lbs per week max)
  • Monitor closely — any pain return = stop immediately

If experiencing shoulder discomfort:

Assessment:

  • Pain during movement = potential impingement
  • Pain in stretched position = mobility limitation
  • Pinching sensation = possible structural issue

Action:

  1. Reduce ROM to pain-free range
  2. Work on shoulder mobility daily
  3. Try cable version (may allow better positioning)
  4. If persists after 1-2 weeks: see healthcare provider

Lower Back Protection (Standing Variation)

Prevention:

  • Brace core maximally before every rep
  • Slight forward lean (5-10°), not upright
  • Never hyperextend lower back
  • Keep glutes engaged throughout
  • Use seated variation if back is sensitive

If lower back hurts:

  • Switch to seated immediately
  • Assess core strength separately
  • May need to strengthen core before returning to standing

Mobility Limitations & Solutions

Common limitation: Can't comfortably get arms overhead with elbows by ears

Causes:

  • Tight chest (pectorals)
  • Tight lats
  • Limited thoracic extension
  • Shoulder capsule tightness

Tests:

  1. Wall test: Stand with back to wall, try to raise arms overhead. Do elbows hit wall?
  2. Overhead squat with PVC: Can you hold PVC overhead without arching back excessively?

Solutions:

  1. Doorway pec stretch — 2-3 sets of 30-60s daily
  2. Lat stretches — overhead reaches, side bends
  3. Thoracic extensions — foam roller, cat-cow
  4. Shoulder dislocations with band/PVC — 2-3 sets of 10 daily
  5. Wall slides — practice overhead position against wall

While improving mobility:

  • Work within current pain-free ROM
  • Try cable version (may allow better positioning)
  • Focus on contraction quality vs. stretch depth

Joint Stress Analysis

Elbow joint:

Type of stress: Moderate tension on tricep tendon at distal attachment (near elbow)

Factors affecting stress:

  • Dumbbell weight (heavier = more stress)
  • Total volume (sets × reps per week)
  • Tempo (slower eccentric = more stress)
  • ROM (full stretch = more stress than partial)
  • Recovery time between sessions

Comparison to other exercises:

  • LESS stress than: Heavy dips, close grip bench press
  • SIMILAR stress to: Cable overhead extensions, skull crushers
  • MORE stress than: Pushdowns, light kickbacks

Risk mitigation:

  • Progressive overload — don't jump weight too fast
  • Adequate recovery — 48-72 hours between overhead sessions
  • Deload weeks — every 4-6 weeks reduce load/volume 40-50%
  • Listen to pain — distinguish muscle burn from joint pain

Shoulder joint:

Type of stress: Isometric stabilization stress holding overhead position

Why overhead position is challenging:

  • Shoulder in flexed position (arms overhead)
  • Must stabilize against weight trying to pull arms down/back
  • Requires rotator cuff and deltoid coordination
  • Some people have limited overhead mobility

Risk factors:

  • Previous shoulder injury (impingement, rotator cuff)
  • Poor posture (rounded shoulders, forward head)
  • Inadequate shoulder mobility
  • Weak rotator cuff

Protection strategies:

  • Improve overhead mobility before heavy loading
  • Strengthen rotator cuff separately
  • Work within pain-free ROM
  • Seated variation provides more stability

Long-Term Joint Health

Protective factors for this exercise:

  • Isolation movement = no other joints compensating or stressed
  • Controlled tempo = no ballistic/shocking forces
  • Natural movement path (free weight) = joints move in preferred pattern
  • Bilateral support = both arms share load on single DB

Risk factors to manage:

  • Overhead position = requires good shoulder mobility
  • Free weight = requires more stabilization than cable
  • Potential for excessive loading = ego lifting with too-heavy DB
  • Drop risk = safety concern if grip fails

Longevity strategies:

StrategyImplementationWhy
Progressive loadingAdd 5 lbs every 2-4 weeks maxTendons adapt slowly — patience required
Deload regularlyEvery 4-6 weeks, reduce 40-50%Allows complete tissue recovery

Warm up thoroughly2-3 light sets before working setsIncreases blood flow, prepares tissues
Recovery nutritionAdequate protein (1.6-2.2g/kg)Supports tendon repair
Sleep7-9 hours nightlyWhen actual tissue repair occurs
Joint Health Note

Overhead dumbbell extensions are moderately demanding on elbows and shoulders. The exercise itself is quite safe when performed correctly, but the overhead position requires good shoulder mobility and stability. Free weight adds stabilization demands compared to cables.

Key for longevity:

  1. Build shoulder mobility BEFORE heavy loading
  2. Progress weight slowly (5 lbs every 2-4 weeks)
  3. Never compromise form for weight
  4. Take deload weeks seriously
  5. Listen to pain signals — joint pain is a red flag, not a challenge

❓ Common Questions

Why overhead instead of pushdowns?

The triceps long head crosses both the elbow AND shoulder joints. Overhead position puts the shoulder in flexion (arm above head), which maximally pre-stretches the long head. This creates 25-40% more long head activation compared to arms-at-side exercises like pushdowns.

For complete tricep development, you need BOTH:

  • Pushdowns (lateral/medial head emphasis)
  • Overhead work (long head emphasis)

Without overhead work, your long head will be under-developed, resulting in less arm mass and imbalanced appearance.

How much weight should I use?

Starting recommendations:

  • Beginners: 15-25 lbs
  • Intermediate: 30-45 lbs
  • Advanced: 50-70 lbs
  • Very advanced: 75+ lbs

Expect to use 30-50% LESS than pushdowns. If you pushdown 60 lbs, expect to use 30-40 lbs overhead.

Better approach: Choose a weight you can do 12 clean reps with perfect form. If your elbows flare, upper arms move, or you can't control the eccentric, it's too heavy.

Standing or seated — which is better?

For most people: Seated is better, especially for heavy weights

Seated advantages:

  • Eliminates lower back stress completely
  • More stable — can use heavier weight
  • Better isolation of triceps
  • Easier to maintain strict form
  • Recommended for 40+ lb dumbbells

Standing advantages:

  • More functional/athletic
  • Works core isometrically
  • No bench required

Recommendation: Start standing with light weights to learn. Progress to seated as weights increase.

My shoulders hurt — what should I do?

First, check your form:

  • Are elbows flaring out to the sides? (Keep them narrow, by ears)
  • Are you arching your back excessively? (Brace core)

If form is perfect and shoulders still hurt:

  • You likely have limited shoulder mobility
  • This is common and fixable

Solutions:

  1. Reduce ROM to pain-free range (don't force deep stretch)
  2. Improve shoulder mobility separately (daily stretching)
  3. Try cable version (may allow better positioning)
  4. Switch to pushdowns temporarily while building mobility

Important: Shoulder pain is a signal, not a challenge. Don't push through it.

Should my upper arms stay completely still?

Yes — absolutely critical.

Your upper arms should stay pinned by your ears throughout the entire movement. Only your forearms move during the exercise.

Common error: Upper arms drift forward during extension or backward during lowering.

Result of arm movement: Exercise becomes a shoulder exercise instead of tricep isolation. Long head activation drops 30-40%.

Self-check: Film yourself from the side. Upper arms should look like statues from start to finish.

How do I grip the dumbbell?

Diamond grip (recommended):

  1. Hold DB vertically with top plate up
  2. Place both palms under the top plate, facing up
  3. Thumbs and index fingers touch, forming a diamond/triangle shape
  4. Other fingers wrap around the handle
  5. Bottom plate hangs down

Both hands should support the weight equally.

Alternative: Cross hands under top plate (less common, but works).

Critical: Grip must be secure. If it feels unstable, use lighter DB until you build grip strength.

Can I go to failure on this exercise?

Not recommended — especially when training alone.

Risks of training to failure:

  • Grip may fail, dropping DB
  • Form breaks down (elbows flare, arms move)
  • Risk of DB hitting head if you lose control

Better approach:

  • Leave 1-2 reps in reserve (RIR 1-2)
  • Stop when form starts to degrade
  • Use a spotter if testing max weight

If you want to train to failure: Use cable overhead extension instead (can't drop the cable).

How do I safely get a heavy dumbbell into position?

NEVER try to curl it directly from floor to overhead. Use this sequence:

  1. Floor to thigh: Pick up DB, place on thigh (top plate up)
  2. Grip it: Set diamond grip while resting on thigh
  3. Thigh to shoulder: Use knee drive to help lift DB to shoulder height
  4. Shoulder to overhead: Press overhead with both arms
  5. Position for exercise: Lower elbows to bent position, DB behind head

After completing set:

  1. Extend arms fully overhead
  2. Lower to shoulder carefully
  3. Lower to thigh
  4. Set down

NEVER drop a dumbbell from overhead position.

My lower back hurts when I do this standing — is that normal?

No, lower back pain is not normal.

Causes:

  • Not bracing core properly
  • Standing too upright (need slight forward lean)
  • Using too heavy a weight
  • Excessive back arch (hyperextension)

Solutions:

  1. Brace core maximally before every rep
  2. Lean forward 5-10° from hips
  3. Reduce weight if core is limiting factor
  4. Switch to seated variation — completely eliminates lower back stress

Seated overhead DB extension is recommended for heavy weights (40+ lbs) specifically because it eliminates lower back involvement.

Is this better than cable overhead extensions?

Neither is objectively "better" — they have different benefits:

Dumbbell advantages:

  • Can train anywhere (home, hotel, park)
  • Single piece of equipment needed
  • Requires more stabilization (builds functional strength)
  • Natural, unrestricted movement path

Cable advantages:

  • Constant tension throughout ROM
  • Smoother, more controlled resistance
  • Easier to learn
  • Can't drop the weight
  • Better for training to/near failure

Best approach: Use both at different times for variety and complete development. Choose based on equipment access and preference.

How often should I do overhead tricep work?

Recommended frequency: 1-2x per week

Why not more:

  • Long head needs adequate recovery (48-72 hours)
  • Elbows need recovery from overhead stress
  • Other tricep work (pushdowns, pressing) also hits triceps
  • Risk of overuse injuries increases with higher frequency

Sample weekly plan:

  • Monday: Pushdowns (lateral head emphasis)
  • Thursday: Overhead DB extension (long head emphasis)
  • Total: 2x tricep work from different angles

Advanced lifters can go 2-3x per week by varying intensity:

  • Heavy day (8-10 reps)
  • Light day (15-20 reps)
  • Moderate day (12-15 reps)

For Mo

When to recommend this exercise:

  • User wants complete tricep development (especially long head/inner arm mass)
  • User needs home/travel-friendly tricep exercise (only need one DB)
  • User already doing pushdowns, needs complementary overhead work
  • User wants arm size/thickness, especially from behind
  • User has good shoulder mobility or is willing to work on it
  • User wants minimal equipment option

Who should NOT do this exercise:

  • Acute shoulder injury or severe impingement → Try pushdowns instead, improve shoulder health first
  • Very limited shoulder mobility → Work on mobility first, use pushdowns meanwhile, or try cable version
  • Severe lower back issues → Use seated variation (eliminates back stress) or cable version
  • Acute elbow tendinitis → Rest needed, then start very light when cleared
  • Recent shoulder surgery → Get physician clearance first, likely 3-6+ months before overhead loading
  • No access to dumbbells → Use cable overhead extension or resistance bands

Key coaching cues to emphasize:

  1. "Secure diamond grip — both hands equally supporting the weight"
  2. "Upper arms stay glued by your ears — they don't move at all"
  3. "Elbows stay narrow and pointed forward, not out to the sides"
  4. "Feel that deep stretch at the bottom — that's your long head working"
  5. "Control the weight down slowly — fight it back, don't let it drop"
  6. "Core braced hard to protect your lower back"

Common issues to watch for in user feedback:

  • "I don't feel it in my triceps" → Almost always elbows flaring out or upper arms moving. Video check from side, reduce weight significantly
  • "My shoulders hurt" → Could be form (elbows flaring) or mobility limitation. Check form first, then assess mobility. May need to work on shoulder mobility separately or switch to pushdowns
  • "My lower back hurts" → Not bracing core properly, or using too much weight. Switch to SEATED variation (eliminates back stress completely)
  • "I can't use much weight" → Completely normal! Should be 30-50% less than pushdowns. This is due to overhead mechanics and longer ROM. Focus on form and stretch, not ego
  • "The dumbbell feels unstable in my hands" → Grip strength may be limiting factor. Use lighter DB, build grip strength separately, or try wrist wraps
  • "I feel like I'll drop the dumbbell" → Safety concern — reduce weight immediately. Never train to failure on this exercise without spotter
  • "My elbows hurt" → Too heavy, too much volume, or pre-existing tendinitis. Cut weight 50%, reduce volume by half, may need 3-5 days rest

Programming guidance:

  • Pair with: Bicep curls (agonist/antagonist superset), pushdowns (complete tricep work different angles), compound pressing earlier in workout
  • Avoid same day as: Multiple other heavy tricep exercises (cumulative elbow stress), excessive overhead pressing (shoulder fatigue)
  • Typical frequency: 1-2x per week for long head emphasis
  • Volume sweet spot: 3-4 sets per session, 6-10 total weekly sets of overhead tricep work (all overhead exercises combined)
  • Progression: Add 5 lbs when can complete 3 × 12-15 with perfect form. Expect progression every 2-4 weeks

Progression signals:

  • Ready to progress: 3 × 12-15 reps with perfect upper arm position (by ears), controlled 2+ second eccentric, full ROM, no pain, RIR 1-2
  • Add weight: 5 lb increments (next heavier dumbbell)
  • Regress if: Elbows flaring consistently, upper arms moving, can't control eccentric, any elbow or shoulder pain develops, stalled 3+ consecutive sessions

Exercise rotation strategy for complete triceps:

  • Overhead work (long head): 1-2x per week — DB or cable overhead extension
  • Pushdown work (lateral head): 2-3x per week — rope, V-bar, or straight bar
  • Total tricep frequency: 2-3x per week across all exercises

Special considerations:

For shoulder mobility issues:

  • Overhead DB extension REQUIRES decent shoulder mobility
  • If limited: work within pain-free range while improving mobility separately
  • Cable overhead extension may allow better positioning
  • Pushdowns are valid alternative until mobility improves
  • Daily shoulder stretching and mobility work essential

For lower back issues:

  • ALWAYS recommend SEATED variation for anyone with back sensitivity
  • Seated completely eliminates lower back stress
  • Standing is fine for healthy backs with light-moderate weight
  • Heavy DBs (40+ lbs) should be done seated by everyone

For beginners:

  • Start very light (15-20 lbs) to learn movement pattern
  • Overhead position is unfamiliar and challenging
  • Focus on feeling the tricep stretch, not loading heavy
  • Build up slowly over weeks/months

For advanced:

  • Can use 50-70+ lb dumbbells with perfect form
  • Great for tempo variations, drop sets, paused reps
  • Two-dumbbell variation adds complexity
  • Seated allows heaviest loading

For home/travel training:

  • This is THE tricep exercise for minimal equipment
  • Single dumbbell is all you need
  • Can do anywhere (home, hotel, park)
  • Pair with push-ups and DB rows for complete upper body

Why this exercise is essential:

  • Only way to fully develop long head — pushdowns alone under-develop it
  • Long head is 2/3 of tricep mass — critical for arm size
  • Creates inner arm thickness — visible from behind
  • Adds 1-2" to arm measurement when properly developed
  • Minimal equipment — accessible for home training
  • Functional strength — overhead stability transfers to athletics

Red flags requiring immediate action:

  • Dumbbell feels like it's slipping/dropping → End set immediately, reduce weight significantly
  • Sharp elbow pain → Stop, rest, ice, may need medical evaluation
  • Shoulder pain/pinching → Stop, assess mobility, may need different exercise
  • Lower back pain → Switch to seated immediately
  • Dizziness from overhead position → Stop, sit down, possible blood pressure issue
  • Sudden "pop" or "snap" in elbow/shoulder → Stop immediately, likely injury, needs medical attention

Important coaching notes:

  • Overhead position is REQUIRED for complete long head development — can't be skipped
  • Start lighter than they think — this exercise is humbling
  • Diamond grip must be secure — safety is paramount
  • Seated is better than standing for most people and all heavy weights
  • Never train to failure without spotter (drop risk)
  • Shoulder mobility is prerequisite — improve it separately if needed
  • Focus on the STRETCH at bottom — that's where magic happens for long head
  • This is about isolation and stimulus, not ego and weight
