Best Triceps Exercise for Growth: What the Research Shows About Overhead Extensions

When it comes to building bigger triceps, most people think about pushdowns, close-grip bench presses, or dips. Overhead triceps extensions tend to get overlooked — yet a growing body of research suggests they may deserve a more prominent spot in your program. A study published in the European Journal of Sport Science examined whether the position of your arm during triceps training affects how much muscle you actually build. The findings offer a practical and evidence-backed reason to reconsider how you're training your triceps, and they highlight how small changes in exercise selection can meaningfully influence results over time.

What This Study Examined

The central question of this research was straightforward: does training the triceps in an overhead position — where the arm is raised above the head — lead to more muscle growth compared to training in a neutral position where the arm stays at the side of the body?

The specific variable under investigation was muscle hypertrophy, or an increase in muscle size, particularly in the long head of the triceps brachii. The triceps is composed of three heads — the long head, the lateral head, and the medial head — and the long head is unique because it crosses the shoulder joint. This means the position of your arm changes how stretched or shortened the long head is during exercise.

Researchers wanted to understand whether loading the triceps at a longer muscle length — as occurs during overhead extensions — would produce greater hypertrophy than loading it at a shorter or more neutral length.

How the Study Was Conducted

Participants in this study were assigned to perform triceps training using one of two exercise variations:

• Overhead elbow extension — performed with the arms elevated above the head, which places the long head of the triceps in a more lengthened position throughout the movement

• Neutral elbow extension — performed with the arms in a more standard position at or near the side of the body

Participants followed a structured resistance training protocol over the course of the study. Muscle size was measured before and after the training period using imaging methods to assess changes in the triceps, with particular attention paid to the long head of the muscle.

The study design allowed researchers to make a direct comparison between the two exercise conditions and determine which approach produced greater triceps development under the same training parameters.

Key Findings

The results of the study suggest that exercise position meaningfully influences triceps hypertrophy:

• Overhead triceps training produced greater hypertrophy in the long head of the triceps brachii compared to the neutral-position extension

• The difference in muscle growth appeared to be linked to the fact that overhead work loads the long head at a longer muscle length

• Training a muscle in a lengthened or stretched position appears to be an important variable in maximizing hypertrophy, based on these findings

• The lateral and medial heads of the triceps may respond differently depending on the position used, though the long head showed the most notable difference between groups

These results add to a growing area of research suggesting that where a muscle is in its range of motion during loading — not just how much weight is used or how many sets are performed — plays a meaningful role in determining adaptation.

What This Means for Training

Taken together, these findings suggest that incorporating overhead triceps work into your program may be worthwhile if your goal is maximizing long head development and overall triceps size.

This matters practically for a few reasons. The long head is the largest of the three triceps heads and contributes significantly to the overall mass and shape of the upper arm. If you're training your triceps exclusively with exercises that keep your arms at your sides — such as cable pushdowns or kickbacks — you may be leaving some muscle-building potential on the table.

That doesn't mean abandoning neutral-position exercises altogether. A well-rounded triceps program likely benefits from including multiple exercise variations that collectively train all three heads. But based on this study, overhead extensions deserve serious consideration as a staple movement rather than an afterthought.

Common overhead triceps exercises include:

• Overhead dumbbell or cable extensions (single or both hands)

• EZ-bar skull crushers performed with the arms angled slightly behind the head, which keeps more tension on the long head

• Incline bench triceps extensions, where the angle of the bench shifts load toward the stretched position

Working with an experienced personal trainer — like those available through Atlas Personal Training in Reno — can help you incorporate these movements with proper technique, since overhead loading does require good shoulder mobility and positioning to perform safely and effectively.

Limitations of the Study

As with all research, it's important to view these findings in context. A few limitations are worth keeping in mind:

• Sample size: Exercise science studies of this type often involve relatively small participant groups, which can affect how broadly the findings generalize to different populations

• Population specifics: The characteristics of the participants — such as training experience, age, and sex — may influence whether results translate to every individual

• Duration: The training period of any single study captures a snapshot of adaptation rather than long-term outcomes; results could differ over a longer training career

• Isolated comparison: The study compares two specific conditions, and real-world training programs are considerably more varied and complex

• Individual variation: People respond differently to training stimuli, and no single study can account for every factor that shapes muscle growth

These limitations don't undermine the findings, but they are a reminder to interpret results as part of the broader picture rather than as the final word on triceps training.

Conclusion

This study offers a useful and practical insight: training the triceps in an overhead position, which loads the long head at a longer muscle length, appears to produce greater hypertrophy than neutral-position extensions. For anyone focused on building well-developed arms, this is a meaningful finding that's worth incorporating into a training program.

Research like this helps inform how evidence-based coaches structure resistance training programs. Rather than simply choosing exercises by feel or habit, understanding why certain movements may be more effective allows for smarter, more intentional programming. If you're looking for structured, individualized guidance, the coaches at Atlas Personal Training can help you build a program that reflects the latest in exercise science — whether you train in person in Reno or prefer online coaching.
