The dumbbell overhead triceps extension stretches and works the triceps.
Seated or standing, hold a dumbbell with both hands by one plate, arms extended overhead.
Lower the dumbbell behind your head by bending your elbows, then raise it back up until your arms are straight.
Your elbows stay pointed upward, close to your head, and your back does not arch.
