Dumbbell Seated Bench Extension
Description
The dumbbell seated bench extension is an overhead tricep extension performed seated on a bench. Holding a single heavy dumbbell with both hands overhead, you bend at the elbows to lower it behind your head, then press it back up. The seated position eliminates lower body cheating and the overhead angle stretches the long head of the triceps.
