Dumbbell Lying One Arm Pronated Triceps Extension
Dumbbell Lying One Arm Pronated Triceps Extension Exercise Description
The Dumbbell Lying One Arm Pronated Triceps Extension trains elbow extension with a focus on the triceps brachii. Performed supine on a bench, the movement isolates the triceps by keeping the upper arm relatively stationary while the forearm moves through a controlled arc. A pronated grip (palm facing your feet) and a neutral wrist help align the forearm with the dumbbell handle for stable force transfer. The lying position offers a solid base, allowing you to concentrate on smooth elbow motion, steady shoulder positioning, and consistent range of motion. Expect primary work from the triceps, with the shoulder girdle and forearm musculature contributing to stabilization as you control the dumbbell path near the side of the head.

How To Do The Dumbbell Lying One Arm Pronated Triceps Extension Exercise
‘- Lie on a flat bench with feet planted and ribs down; maintain a neutral spine.
– Hold a dumbbell in one hand using a pronated grip (palm faces your feet). Arm is straight above the shoulder; wrist neutral. Lightly retract and depress the shoulder blade.
– Set the upper arm vertical or slightly angled toward your head; point the elbow toward the ceiling.
– Inhale. Keeping the upper arm still, bend the elbow to lower the dumbbell in an arc toward the outside of your head (temple/ear). Avoid touching the head.
– Lower until the forearm is about parallel to the floor or you feel a controlled stretch—no shoulder movement.
– Exhale. Extend the elbow to return the dumbbell over the shoulder. Do not forcefully lock the elbow.
– Keep the wrist neutral, elbow close, and torso quiet throughout.
– Use both hands to safely get the dumbbell into and out of position before switching arms.
Dumbbell Lying One Arm Pronated Triceps Extension Tips
‘- Lie on the bench with feet planted, ribs down, and a neutral spine.
– Use a pronated grip with the palm facing your feet and keep the wrist neutral.
– Start with the arm straight above the shoulder, elbow pointing toward the ceiling, and the shoulder blade lightly retracted and depressed.
– Set the upper arm vertical or slightly angled toward your head and keep it still throughout the movement.
– Inhale as you bend the elbow and lower the dumbbell in an arc toward the outside of your head (temple/ear).
– Avoid letting the dumbbell touch your head at the bottom.
– Lower until the forearm is about parallel to the floor or you feel a controlled stretch, without letting the shoulder move.
– Exhale as you extend the elbow to bring the dumbbell back over the shoulder, without forcefully locking the elbow.
– Keep the wrist neutral, the elbow close, and the torso quiet for the entire rep.
– Use both hands to get the dumbbell into and out of position before switching arms.
Dumbbell Lying One Arm Pronated Triceps Extension Beginner Introduction
The Dumbbell Lying One Arm Pronated Triceps Extension is a single‑arm dumbbell exercise that emphasizes movement at the elbow while the rest of the body stays steady on a flat bench. A dumbbell is held in an overhand position above the shoulder, with the elbow pointed upward. From there, the forearm travels in a smooth curve near the side of the head, while the upper arm stays nearly in place. This setup highlights work in the triceps on the back of the upper arm, with the shoulder area and forearm muscles contributing to control.
Because the lifter is lying down, the bench provides a solid base that supports a calm torso and steady shoulder position. Attention shifts to a consistent bending and straightening of the elbow, a straight wrist, and a repeatable path for the weight. The movement invites slow, deliberate motion rather than speed, encouraging precision through the same range each repetition while the dumbbell is guided into and out of place with care between arms.
