The dumbbell lying triceps extension works the triceps while lying on a bench.
Lying on a flat bench, hold a dumbbell in each hand with arms extended above your chest, palms facing each other.
Bend your elbows to lower the dumbbells on each side of your head, then raise them back up until your arms are straight.
Only your forearms move: your elbows stay pointed toward the ceiling.
