Dumbbell Lying One Arm Pronated Triceps Extension
Dumbbell Lying One Arm Pronated Triceps Extension Exercise Description
The dumbbell lying one arm pronated triceps extension is a single‑joint elbow extension that targets the triceps brachii (long, lateral, and medial heads). Performed supine on a bench with a pronated (overhand) grip, it emphasizes controlled elbow motion while keeping the upper arm relatively stationary. Unilateral execution allows focused attention to shoulder positioning, wrist alignment, and symmetrical range of motion from side to side. The pronated grip orients the forearm so the palm faces the feet, which many lifters find helps maintain a neutral wrist and consistent force line over the elbow joint. Done with steady control, it provides clear triceps loading while minimizing shoulder and torso movement.

How To Do The Dumbbell Lying One Arm Pronated Triceps Extension Exercise
‘- Lie supine on a flat bench with feet planted and ribs down; maintain a neutral spine.
– Hold a dumbbell in one hand with a pronated/overhand grip (palm facing your feet); keep the wrist neutral.
– Set the shoulder by gently retracting and depressing the scapula against the bench.
– Start with the working arm vertical above the shoulder, elbow extended but not hyperextended.
– Keep the upper arm fixed; point the elbow toward the ceiling throughout.
– Inhale or brace, then bend the elbow to lower the dumbbell in a controlled arc toward the outside of the same‑side temple/ear.
– Stop when you feel a comfortable stretch in the triceps without the shoulder drifting or the elbow flaring excessively.
– Extend the elbow to return the dumbbell to the start, finishing with the elbow straight without locking hard.
– Keep the wrist stacked (knuckles over forearm); avoid letting it bend backward or forward.
– Maintain light scapular tension; avoid arching the back or shrugging the shoulder.
– Move smoothly; do not bounce or let the dumbbell contact the face or head.
– To finish the set safely, use the free hand to guide the dumbbell to your chest, then sit up.
Dumbbell Lying One Arm Pronated Triceps Extension Tips
‘- Keep your ribs down and spine neutral as you lie on the bench with feet firmly planted.
– Use a pronated (overhand) grip with the palm facing your feet and keep the wrist neutral.
– Gently retract and depress your shoulder blade into the bench before you start the set.
– Keep your upper arm still and your elbow pointing straight up toward the ceiling throughout the movement.
– Lower the dumbbell in a smooth, controlled arc toward the outside of your temple/ear on the working side.
– Only lower until you feel a comfortable stretch in the triceps, without the shoulder drifting or the elbow flaring excessively.
– Extend the elbow to return to the start, finishing with a straight arm but without a hard lockout.
– Keep the wrist stacked so the knuckles stay in line over the forearm; don’t let it bend backward or forward.
– Maintain light shoulder blade tension and avoid arching your back or shrugging your shoulder.
– Move smoothly without bouncing or letting the dumbbell touch your face or head, and use your free hand to guide the dumbbell to your chest before sitting up.
Dumbbell Lying One Arm Pronated Triceps Extension Beginner Introduction
The dumbbell lying one arm pronated triceps extension is a lying dumbbell exercise that zeroes in on the back of the upper arm. Performed while resting face up on a flat bench, it uses a palm‑down grip so the palm faces toward the feet. The movement centers on bending and straightening a single elbow, with the arm starting above the shoulder and the dumbbell traveling in a smooth path beside the head. Because only one side works at a time, attention can go to how the shoulder sits on the bench, how straight the wrist feels, and whether both arms move through a similar distance.
This is a controlled, single‑joint extension that highlights elbow action while limiting help from the shoulders and torso. A steady tempo and a relatively still upper arm bring clear tension into the triceps throughout the motion. The palm‑down hand position also encourages a straighter wrist and a consistent line of effort through the elbow, which many lifters find useful for feeling the back of the arm working without excess body movement.
