Lying Dumbbell Pronation

Setup

1. 01Lie on a flat bench holding a light dumbbell by one end so the load is offset.
2. 02Bend the elbow to 90 degrees and rest the upper arm against your side or the bench.
3. 03Start with the palm facing up and the dumbbell head pointing away from the midline.
4. 04Keep the wrist straight so rotation comes from the forearm, not the wrist joint.

Execution

1. 01Rotate the forearm so the palm turns from facing up to facing down.
2. 02Move slowly and let the offset dumbbell head resist the rotation.
3. 03Pause briefly in the fully pronated position.
4. 04Rotate back to the palm-up start under the same control.

Checkpoints

• -Elbow stays bent at 90 degrees and pinned in place.
• -Rotation is smooth with no jerking at the end range.
• -Only the forearm rotates; the shoulder does not roll to help.
• -The dumbbell stays gripped near one end to keep the leverage offset.

Common mistakes

• -Gripping the dumbbell in the middle, which removes the resistance.
• -Rotating from the shoulder instead of the forearm.
• -Using a dumbbell too heavy to control at the end ranges.
• -Flicking the weight over instead of resisting through the full arc.
