Dumbbell Lying Pronation
Muscles worked
Instructions
- 1Lie on a flat bench face down with one arm holding a dumbbell and the other hand on top of the bench folded so that you can rest your head on it.
- 2Bend the elbows of the arm holding the dumbbell so that it creates a 90-degree angle between the upper arm and the forearm.
- 3Now raise the upper arm so that the forearm is perpendicular to the floor and the upper arm is perpendicular to your torso. Tip: The upper arm should be parallel to the floor and also creating a 90-degree angle with your torso. This will be your starting position.
- 4As you breathe out, externally rotate your forearm so that the dumbbell is lifted forward as you maintain the 90 degree angle bend between the upper arms and the forearm. You will continue this external rotation until the forearm is parallel to the floor. At this point you will hold the contraction for a second.
- 5As you breathe in, slowly go back to the starting position.
- 6Repeat for the recommended amount of repetitions.

About Dumbbell Lying Pronation
The dumbbell lying pronation is an uncommon isolation exercise that specifically strengthens the forearm's pronator muscles, responsible for rotating the wrist inward. Lying face-down on a flat bench with the elbow bent at 90 degrees and the upper arm perpendicular to the torso, you rotate the forearm forward to raise the dumbbell while keeping the elbow angle fixed, then return slowly to the starting position. This isolated rotational movement is particularly useful for racquet or throwing sports, and for preventing elbow pain linked to an imbalance between the pronator and supinator muscles.

lightbulbExecution tips
- lightbulbKeep the upper arm and elbow angle perfectly fixed
- lightbulbUse a light dumbbell — this is a technical movement
- lightbulbHold the contraction for a second at the end of the forward rotation
- lightbulbControl the return, don't let the dumbbell drop
warningCommon mistakes
- warningUsing too heavy a load and breaking form
- warningLetting the upper arm move during the rotation
- warningRushing the movement without control through the range
- warningMoving the shoulder instead of only the forearm
