Overhead Tricep Extension
Muscles worked
Instructions
- 1To begin, stand up with a dumbbell held by both hands. Your feet should be about shoulder width apart from each other. Slowly use both hands to grab the dumbbell and lift it over your head until both arms are fully extended.
- 2The resistance should be resting in the palms of your hands with your thumbs around it. The palm of the hands should be facing up towards the ceiling. This will be your starting position.
- 3Keeping your upper arms close to your head with elbows in and perpendicular to the floor, lower the resistance in a semicircular motion behind your head until your forearms touch your biceps. Tip: The upper arms should remain stationary and only the forearms should move. Breathe in as you perform this step.
- 4Go back to the starting position by using the triceps to raise the dumbbell. Breathe out as you perform this step.
- 5Repeat for the recommended amount of repetitions.

About Overhead Tricep Extension
The overhead dumbbell triceps extension isolates all three heads of the triceps, with a marked stretch on the long head — the one that gives size to the back of the arm. Seated or standing, you hold one dumbbell with both hands behind the neck, elbows pointing at the ceiling and tucked, then extend the arms upward without flaring them out. It is the stretch under load in the bottom position that makes this movement so effective for hypertrophy. Keep the back straight and brace the trunk: arching the lower back is the most common mistake.

warningCommon mistakes
- warningLetting the elbows flare out, shifting load to the shoulders
- warningArching the back when the dumbbell is too heavy
- warningCutting the range short and losing the long-head stretch
- warningMoving the whole arm instead of hinging only at the elbow
- warningUsing too heavy a load that breaks elbow position

- tuneLying skull crusher — a lying variation that isolates the elbow more
person_checkWho it's for and level
The overhead dumbbell triceps extension suits all levels, from beginners learning to isolate the triceps to advanced lifters targeting the long head specifically. It requires decent shoulder mobility to hold the position behind the neck comfortably, so anyone with shoulder stiffness should warm up carefully first or favor a cable variation instead. It's an excellent complement to heavy pressing movements for adding size to the back of the arm.
shieldSafety and precautions
The main risk with this exercise concerns the lower back and shoulder: too heavy a load tempts you to arch to compensate, which is why bracing the core before every rep matters so much. Always keep the elbows fixed and pointing forward, never flaring outward, to protect the joint. If you feel shoulder discomfort in the bottom position behind the neck, reduce the range or temporarily switch to a cable extension, which is easier on the joint.
calendar_monthWhere to place it in your program
Place this exercise at the end of a triceps session, after a compound movement like the bench press or dips, for 3 to 4 sets of 10 to 15 reps. Keep the tempo slow on the way down to make the most of the long head's stretch. It works well both as pure isolation and as a finisher with an intensity technique like descending reps. Two sessions per week, spaced at least 48 hours apart, are enough to progress well without excess elbow fatigue.
helpFrequently asked questions
Seated or standing for the overhead tricep extension?
The seated version with a backrest stabilizes your torso and lets you focus on the triceps, especially under heavier loads.
One dumbbell or two?
A single dumbbell held with both hands is the most common and stable option; two dumbbells add coordination demand but isolate each arm.
Should I keep my elbows tucked in?
Yes: the closer the elbows stay to the head and the more fixed they are, the harder the triceps works. If they flare out, the shoulder takes over and the long-head stretch shrinks.
Which muscle gets the most stretch in this movement?
The long head of the triceps, which crosses the shoulder, benefits most from the stretch in the bottom position behind the neck.
Can this be done with a kettlebell?
Yes, a kettlebell held by the handle also works, though a standard dumbbell remains more comfortable for the two-handed grip.
How many reps should I aim for?
Between 10 and 15 reps per set works well for this triceps isolation movement.
Is this a good exercise for beginners?
Yes with a light load, but it demands solid core bracing to avoid arching the back.
Can I use a barbell instead?
Yes, the EZ-bar behind-the-neck version also exists and allows slightly heavier loading.
Do I need a bench for the seated version?
A bench with a backrest stabilizes the torso better, but a sturdy stool or chair can also work.
What's the difference from a cable extension?
The cable keeps constant tension throughout the movement, while the dumbbell emphasizes the stretch more at the bottom.
Can beginners try this exercise safely?
Yes with a light dumbbell and a strong core brace, though anyone with shoulder issues should check with a professional first.
