Overhead Tricep Extension

Overhead tricep extensions place the long head of your triceps under maximum stretch—the position research suggests may provide superior muscle growth stimulus. Unlike pushdowns which work the triceps in a shortened position, overhead extensions challenge the long head through its full range with constant tension at the stretched position.
Keep your elbows close to your ears pointing forward—not flared outward. Lower the weight behind your head until you feel a deep stretch in your triceps, then extend back up. Do not arch your lower back excessively; if you cannot maintain a neutral spine, reduce the weight.
Muscles worked: Overhead Tricep Extension
Why This Exercise Works
The overhead tricep extension is an isolation exercise that specifically targets the long head of your triceps — the largest of the three tricep heads. What makes overhead extensions unique is the fully stretched position of the long head when your arms are overhead. This stretched position creates maximum tension on the long head, which contributes most to overall tricep size.
Your triceps have three heads: the long head, lateral head, and medial head. The long head is unique because it crosses both the elbow and shoulder joints, originating from your scapula rather than your upper arm bone. This means the long head is fully stretched when your arm is overhead and your elbow is bent — exactly the position at the bottom of an overhead extension.
Research on muscle physiology shows that training muscles in their lengthened position may provide superior hypertrophy stimulus. The overhead extension exploits this principle by placing the long head under maximum stretch while loaded. This is why overhead extensions are often recommended as the best exercise for building overall tricep mass.
When you extend your elbow against resistance from the overhead position, all three tricep heads contract. However, the long head is preferentially recruited because it starts in a stretched position and has the most mechanical advantage through the range of motion. The lateral and medial heads assist but contribute less than in pushdown variations.
Your shoulder stabilizers work to maintain the overhead arm position throughout the movement. Your core activates to prevent excessive arching of the lower back. These stabilization demands are why seated versions are often recommended — they reduce the balance requirements.
The dumbbell variation allows natural wrist and elbow positioning. Cables provide constant tension throughout the movement. Both are effective. The key is maintaining the overhead arm position with elbows close to your head and controlling the stretch at the bottom.
Overhead tricep extensions rank highly as a premier tricep exercise for hypertrophy. They produce 40 percent more triceps growth than pushdowns—a finding Dr. Mike Israetel's research at Renaissance Periodization has documented. Getting the long head into a lengthened position appears critical for muscle growth, aligning with stretch-mediated hypertrophy principles: exercises that load a muscle in its lengthened position may provide a superior growth stimulus.
MySetPlan programming data confirms this: overhead tricep extensions are the most frequently programmed tricep isolation exercise across all user plans. They appear more often than pushdowns, skull crushers, or kickbacks. Users who include overhead extensions in their programs alongside a pushdown variation report the most complete tricep development — matching the long head plus lateral head coverage pattern recommended by strength coaches.
For complete tricep development, combine overhead extensions (long head emphasis) with pushdowns (lateral head emphasis) and close-grip pressing (all heads).

Overhead Tricep Extension form guide
- 1
Sit or stand holding dumbbell with both hands overhead.
- 2
Grip the dumbbell by upper plates, arms extended.
- 3
Lower weight behind head by bending elbows.
- 4
Keep upper arms close to ears throughout.

What are the best tips for the Overhead Tricep Extension?
Keep elbows pointed forward, not flared.
Great stretch for long head.
Can use EZ bar, cable, or single dumbbell.
When to Use the Overhead Tricep Extension
Program overhead extensions when long head development is the priority. They pair well with pushdowns which emphasize the lateral head. Use them as your primary tricep isolation movement on arm day or after compound pressing on push days.
What are common Overhead Tricep Extension mistakes to avoid?
Letting elbows flare wide.
Arching back excessively.
Moving upper arms during reps.
Is the Overhead Tricep Extension right for you?
Lifters prioritizing arm size, anyone whose triceps lack the long head mass that creates horseshoe shape, and all levels wanting complete tricep development.
How many sets and reps of Overhead Tricep Extension should you do?
Recommendation: 3 sets of 12-15 reps. Rest 60 seconds.

Where to Use in Your Workout
After compound pressing movements like bench press and overhead press. Tricep isolation comes after heavy compound work.
Sample Workout Blocks
Workout: Arm Day (Tricep Focus) 1. Close-Grip Bench Press: 4 sets × 6 reps 2. Dips: 3 sets × 8 reps 3. Overhead Tricep Extension: 3 sets × 12 reps 4. Rope Pushdown: 3 sets × 12 reps 5. Barbell Curl: 3 sets × 10 reps 6. Hammer Curl: 2 sets × 12 reps Rest 60 seconds between overhead extension sets. This workout balances compound and isolation work for complete tricep development.

Variation Details
Single-Arm Overhead Extension
Perform overhead extensions one arm at a time. Allows each arm to work independently and can help fix strength imbalances. Uses lighter weight but more control.
Cable Overhead Extension
Use a high cable pulley with a rope attachment. Cables provide constant tension throughout the movement and are gentler on elbows than free weights.
EZ Bar Overhead Extension
Use an EZ curl bar instead of a dumbbell. The angled grip is more comfortable for wrists. Allows heavier loading than dumbbells.
Skull Crusher
Lying overhead extension performed on a bench. The long head is less stretched than standing variations but allows heavier weight.
Overhead Tricep Extension vs Other Exercises
Overhead extensions target the long head with a stretched position. Pushdowns target the lateral head with a shortened position. Both are essential for complete tricep development. Use both in your program.
Both target the long head through overhead positioning. Overhead extensions provide more stretch; skull crushers allow heavier weight. Skull crushers are lying down; overhead extensions are upright. Both are effective.
Dumbbell and cable versions of the overhead extension both stretch the long head, but the tension profiles differ. Dumbbell work lets you train unilaterally and use heavier loads. The cable version keeps tension constant through the full range with no dead spot at the top. Most lifters benefit from alternating between them across training blocks.
Frequently Asked Questions About the Overhead Tricep Extension
The long head crosses both your elbow and shoulder joints. When your arm is overhead, the long head is fully stretched. Training muscles in their stretched position provides excellent growth stimulus.
Either works. One dumbbell held with both hands is easier to control. Two dumbbells allow each arm to work independently but require more coordination. Start with one dumbbell.
Both work. Seated provides more stability and reduces lower back stress. Standing requires more core activation. Use seated if you have lower back issues or want to focus purely on your triceps.
Lower until you feel a good stretch in your triceps but stop before shoulder discomfort. A controlled stretch is more important than maximum depth. Don't force range of motion.
Elbow pain often comes from going too heavy or not warming up. Reduce weight, warm up properly, and control the movement. If pain continues, try cable variations which are gentler on elbows.
They target different tricep heads. Overhead extensions emphasize the long head; pushdowns emphasize the lateral head. Both are valuable. Use overhead extensions if you want bigger overall triceps.
2-4 sets of 10-15 reps is typical for hypertrophy. Overhead extensions are isolation work, so moderate volume is sufficient. Focus on quality reps with good stretch.
Yes, the Overhead Tricep Extension can be done at home with a dumbbell. It requires minimal space and is a great option for home workouts targeting triceps.
