This exercise is especially good for the ending range of motion in the tricep. It works the long head of the tricep and is responsible for improving definition in the entire muscle.
How to do: 1.Bend over fully at the hips. Your upper body should be parallel to the floor.
2. Your knees should be slightly bent and your feet flat.
3. Get a neutral grip on a dumbbell. Bend your arm so that your upper arm is along side your body and your forearm is pointing straight down.
4. Support your body by placing the hand of your free arm on the bench.
5. Inhale, hold your breath and extend your arm out until it is straight.
6. After your arm is fully extended, squeeze your tricep to make sure it is fully extended. At the finish of the movement, the dumbbell should be above your back.
7. Exhale and slowly return to the starting position.
