Overhead triceps extension
Training the triceps with the arm overhead stretches the long head, and in a 12-week MRI trial it grew the triceps about 1.4 times as much as the same exercise with the arm by the side, despite lighter loads. It is the strongest single choice for triceps size, though that rests on one well-run trial.
What the science says
- More triceps growth than the arm-by-side position Moderate evidence
Maeo et al. (2023) trained one arm overhead and the other in the neutral position with cable elbow extensions for 12 weeks (21 adults, MRI): whole-triceps volume grew 19.9% vs 13.9%. One well-designed trial, so moderate.
- The long head benefits most Moderate evidence
In the same trial the long head, which crosses the shoulder and is stretched overhead, grew 28.5% vs 19.6%; the lateral and medial heads also grew more (14.6% vs 10.5%).
- Lighter loads, so easier on the joints Moderate evidence
Overhead loads were 34–39% lower than in the neutral position, yet growth was greater, which the authors note means lower mechanical stress for the same or better result.
- Activation patterns are similar to lying extensions Moderate evidence
Alves et al. (2018) found overhead and lying dumbbell elbow extensions showed similar triceps activation patterns in 21 trained men, so you don't need both in the same routine. This is EMG only.
How to do it
Muscles trained: triceps
- Use a cable (facing away) or a single dumbbell held with both hands
- Keep the upper arms close to the head and pointing up
- Lower behind the head until you feel a deep stretch in the back of the arm
- Extend to straight elbows without flaring them wide
- Brace the trunk so the lower back doesn't arch
How to apply it
Make an overhead extension your main triceps exercise, using a cable or dumbbell, with a full stretch at the bottom of each rep.
Who should be careful
For healthy adults it is low-risk with moderate loads. People with limited shoulder mobility or shoulder pain in the overhead position should use a smaller range or a cable from a low pulley, and see a physician or physical therapist if pain persists. Elbow pain is a reason to lighten the load.
Frequently asked questions
Is the overhead extension the best triceps exercise?
It has the best direct evidence: in one 12-week MRI trial it grew the triceps about 1.4 times as much as the same exercise with the arm by the side. That is one trial, so treat it as a strong lead, not a final word.
Do I need a lot of weight?
No. Loads were 34–39% lower overhead, yet growth was greater. Go close to failure with a full stretch.
Cable or dumbbell?
The trial used a cable. A dumbbell version trains the same position; use whichever lets you reach the full stretch comfortably.

More exercises
- Back squat Strong evidence
The barbell back squat reliably builds the quadriceps, glutes and adductors and is one of the best-studied lower-body exercises in training research.
- Front squat Moderate evidence
The front squat holds the bar on the front of the shoulders, which keeps the torso more upright and loads the knees less than the back squat while recruiting the thigh muscles about as much.
- Bulgarian split squat Moderate evidence
The Bulgarian (rear-foot-elevated) split squat trains one leg at a time and builds the quads and glutes with far less load on the bar than a back squat.
- Leg press Strong evidence
The leg press builds the quadriceps about as well as free-weight squats and also grows the glutes and adductor magnus, with no balance or spinal-loading limit.
- Hack squat (machine) Moderate evidence
The machine hack squat lets you squat deep on a fixed track with your back supported, which makes it easy to push the quads close to failure.
- Romanian deadlift Moderate evidence
The Romanian deadlift is a hip hinge that loads the hamstrings and glutes at long muscle lengths, and trials of stiff-leg deadlifts and similar hip-extension exercises show real hamstring growth, mainly in the semimembranosus and biceps femoris long head.
