Overhead Tricep Extension: Completing Your Tricep Development

The overhead tricep extension is the most important tricep exercise that most gym-goers underutilize. While pushdowns effectively target the lateral and medial tricep heads, the long head — which comprises approximately 50–60% of the tricep's total mass — is only fully stretched (and therefore most effectively loaded) when the arm is overhead. Any program that exclusively uses pushdowns and dips is leaving substantial tricep development on the table.

Why the Long Head Requires Overhead Positioning

The long head of the triceps has a unique anatomical distinction: it crosses the shoulder joint (attaching to the scapula) as well as the elbow. This means the long head has two functions — elbow extension (like all tricep heads) and contributing to shoulder extension.

The consequence: when the arm is raised overhead (shoulder flexed above 90 degrees), the long head is stretched at both the shoulder and the elbow simultaneously — creating a maximum length position. When the arm is at the side (as in pushdowns), the long head is in a shorter, less stretched position.

Maximum stretch under load → maximum growth stimulus. Overhead tricep exercises are the only way to achieve the long head's maximum stretch.

Dumbbell Overhead Tricep Extension

Setup: Hold one dumbbell with both hands (diamond grip — both hands supporting the inside of the weight plates on one end). Or hold two dumbbells, one in each hand.

Position: Arms overhead, elbows pointing toward the ceiling. Upper arms remain vertical — they do not move during the exercise. Only the forearms move.

Execution: Lower the dumbbell(s) behind the head by bending the elbows — forearms travel backward toward the top of the shoulders. Lower until maximum elbow flexion (the stretched position) is reached, then extend back to the overhead starting position.

Elbow position: Elbows remain pointing upward, shoulder-width apart. Elbows that flare outward create shoulder strain and reduce long head stretch. Point the elbows toward the ceiling throughout.

Full range: Reach maximum flexion at the bottom (maximum long head stretch), then full extension at the top (maximum contraction). Don't shortchange either extreme.

Cable Overhead Extension

Setup: Low pulley position, rope or bar attachment. Facing away from the machine.

Position: Hold the rope overhead (arms extended upward), then allow forearms to flex backward behind the head.

Advantage: The cable provides consistent tension through the full range — the rope is never weightless as a dumbbell can be at the top.

Skull Crushers (Lying Tricep Extension)

The skull crusher (lying on a bench, lowering an EZ bar or dumbbells toward the forehead) is a related overhead extension variation:

Setup: Lie on a flat bench. Hold EZ bar or dumbbells with arms extended above the chest.

Execution: Lower the bar toward the forehead by bending the elbows — only the elbows bend. Press back to the starting position.

Shoulder position: Unlike the true overhead extension (arms vertically overhead), the skull crusher has the arms at approximately 90 degrees to the torso. This is a partial overhead position — more long head involvement than pushdowns, but less than true vertical overhead.

Programming Overhead Extensions

After pushdowns: 3 × 10–15 overhead extensions after pushdowns covers both the lateral/medial heads (pushdowns) and the long head (overhead extensions) comprehensively.

Alternative: Include one overhead extension variation and one pushdown variation in each tricep session.

FAQs: Overhead Tricep Extension

Q: Why do my elbows hurt during overhead tricep extensions? A: Elbow pain during overhead extensions typically indicates either too much weight (excessive joint stress), elbows flaring outward (check alignment), or insufficient warm-up. Start lighter, ensure elbows point upward, and warm up with higher-rep lighter sets before heavier work.

Q: Is the overhead extension necessary if I do skull crushers? A: Skull crushers target the long head in a partial overhead position. True overhead extensions (arms vertically overhead) provide greater long head stretch. Both are valuable, but if you're going to choose one, the full overhead extension provides the more complete long head stimulus.
