Overhead triceps extension
Straightening the elbows with the arms overhead — and the overhead position is what makes it different from a pressdown.

What it is
Hold a single dumbbell in both hands, or one in each hand, directly overhead with the arms extended.
Keeping your upper arms still and pointing at the ceiling, bend your elbows to lower the weight behind your head. Then straighten the elbows to return to the start.
The upper arms do not move. Only the forearms travel. If the elbows drift forward and back, it has become a press.
What it demands
Elbow extension strength, and enough overhead shoulder range to hold the position for a set.
The reason to do it overhead rather than in front follows from anatomy. The long head of triceps brachii is the only one of the three that crosses the shoulder, so raising the arm lengthens it. Working a two-joint muscle from a lengthened position loads it differently from working it from a shortened one — which is why an overhead extension and a pressdown are not interchangeable, and why the overhead version is the one to choose if only one is available.
Trunk control, for the same reason as the overhead press: with weight above and behind your head, the compensation for missing shoulder range is to arch the lower back.
What usually goes wrong
The elbows flare and drift. They stay pointing forward and roughly still. Drifting turns it into an inefficient press.
Arching the lower back. Ribs down. If the position cannot be held without arching, the range is not there yet and a one-arm version or a lighter weight is the answer.
Going too heavy. The elbow is in a long-lever position and the load at the joint is higher than the dumbbell suggests.
Behind the neck rather than behind the head. The weight lowers behind the head, in line with the arms, not down onto the neck.
Where it sits
An isolation movement with a clear mechanical reason to exist, which is why it is here and a pressdown is not: the overhead position is the one that reaches the long head, and it needs no cable machine.
It pairs with the overhead press, which trains the same muscle as part of a pattern, and with the dumbbell curl on the other side of the elbow.
