Seated Single Arm Overhead Extension (Dumbbell)

Also known as: Seated Single Arm Overhead Extension (Dumbbell).

Single-arm dumbbell triceps extension seated upright on a flat bench with the upper arm held beside the head.

How to perform this exercise

1. Sit upright on a stable flat bench with both feet grounded. Hold one dumbbell in the right hand and rest the left hand on the hip.
2. Raise the right upper arm beside the head and bend the elbow so the weight hangs behind the head. Keep the neck neutral and abdomen braced.
3. Extend only the elbow to raise the dumbbell, keeping the upper arm nearly still and avoiding extra lower-back arching.
4. Lower slowly through a comfortable shoulder range and change arms after the set.
