START: Lie faceup on a flat bench with your feet flat on the floor. Grasp a dumbbell in each hand and hold them directly above you with your palms facing inward (neutral grip) and your arms extended.
MOVEMENT: Keeping your upper arms stationary and perpendicular to the bench, bend your elbows to bring the dumbbells toward the top/sides of your head. As your inner elbow joints approach 90-degree angles, pause and then smoothly reverse direction by pressing back to full arm extension. Squeeze your triceps at the top of the movement.
WHEN TO USE IT: The dumbbell lying triceps extension is an excellent move to begin your triceps routine. After 12 warm-up sets, do this exercise first before movements such as the triceps pressdown or dumbbell kickback. Perform 23 sets of 1215 reps. You can also do these one arm at a time, using your nonworking arm to spot yourself for those few extra reps.

Bonus Tips:
>> Concentrate on keeping your elbows stable.
>> Lower the dumbbells to a point just above your forehead.
