The single-dumbbell lying triceps extension works the triceps with a single dumbbell held in both hands.
Lying on a flat bench, hold a dumbbell with both hands by the handle, arms extended above the chest.
Bend your elbows to lower the dumbbell behind the top of your head, then push back up until your arms are extended.
Your elbows remain pointed toward the ceiling and tucked inward.
