DUMBBELL OVERHEAD TRICEPS EXTENSION
Isolation exercise that raises the arms above the head, stretching the long head of the triceps to the extreme and increasing arm volume.
Sit on a bench or stand upright and hold one dumbbell in both hands. Grasp the inner plate of the dumbbell as if holding it and raise it high above your head. Keep your elbows next to your ears, inhale and slowly lower the dumbbells behind your head. After you feel your triceps sufficiently stretched, exhale and straighten your arms to return to the starting position.

Is it better to do it standing or sitting?
Performing while sitting reduces the strain on the lower back and allows more focus on the triceps, so it is recommended for beginners.
STEP BY STEP
4 Steps for One Complete Rep

- 1
Ready and Grip
Hold the dumbbell with both hands and raise it above your head. Open your chest and tense your core to stabilize your spine.
- 2
Lower the dumbbell (relax)
While keeping your elbows fixed, slowly lower the dumbbells behind your head. Lower deeply so that your elbows are bent at least 90 degrees.
- 3
Bottom stretching
Stay at the point where your triceps are stretched for 1 second and maintain tension.
- 4
Push vertically (retract)
Using your elbows as an axis, push the dumbbells back up above your head. Contract your triceps hard at the top.
LONG HEAD HYPERTROPHY
Completion of the back muscles of the arm, long head of the triceps
The long head of the triceps is attached to the scapula and receives the greatest stretch when the arms are raised overhead. Overhead extensions take advantage of this anatomical feature to deliver a strong eccentric load to the long head.
As the long head develops, the volume of the back becomes overwhelmingly better when the arms are lowered. To increase the effect, you must maintain abdominal pressure throughout the movement so that your lower back does not bend excessively, and be careful not to swing your elbows back and forth.

RANGE, LOAD & TEMPO
Choose a range and load that keep the Dumbbell Overhead Triceps Extension repeatable
The useful range of motion ends before your torso or working joints have to change position to move the load. Keep the triceps brachii producing the movement while the anterior deltoid · forearms · core support the same alignment from the first repetition to the last.
Use a controlled lowering phase of about two to three seconds and avoid bouncing through the transition. If the final repetitions become shorter, faster, or visibly different from the first, reduce the load or stop the set before technique breaks down.

Key point: Progress the Dumbbell Overhead Triceps Extension only after every repetition follows the same path without joint pain.
TROUBLESHOOTING
Fix the cause of a mistake, not just its appearance
Back hyperextension
- What you see
- A posture in which the lower back is bent like a bow when lowering the dumbbell.
- Likely cause
- Lack of core strength or limited shoulder mobility.
- How to correct it
- Tighten your abdominal muscles to press your ribs down and your hips to keep your spine neutral.
Elbow spread
- What you see
- A phenomenon in which the elbows are spread close to 90 degrees to both sides.
- Likely cause
- Attempts to support weight by engaging shoulder muscles.
- How to correct it
- Concentrate the load on your triceps by maintaining the feeling of bringing your elbows towards your ears.
REGRESSION & PROGRESSION
Match the difficulty before adding load
One Arm Dumbbell Overhead Extension
Perform one arm at a time to expand your range of motion and feel the stimulation of each arm precisely.
Cable Overhead Extension
Uses cables to maintain constant tension throughout all sections of the movement.
BEGINNER PROGRAM
A practical starting framework
Dumbbell overhead extension is one of the best exercises to give your arms more dimension. Perform in a gentle rhythm.
Frequency
1-2 times a week
Include stretching-focused items in your triceps workout routine.
Volume
3~4 sets, 12~15 times
Choose a weight that allows you to feel accurate stretching and contraction rather than a heavy weight.
- Hold the dumbbells firmly with your palms so as not to lose them.
- Slow your tempo on the way down to improve tension on your triceps.
- Breathe in when going down and exhale when going up.
Frequently asked questions
My elbow hurts.
The weight may be too heavy or the elbow angle may be unstable. Try reducing the weight and keeping your elbows more planted.
