How to Do Dumbbell Lying Pronation

Step-by-step instructions, muscles worked and workouts that use the dumbbell lying pronation.

How to do it

1. Lie 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.
2. Bend the elbows of the arm holding the dumbbell so that it creates a 90-degree angle between the upper arm and the forearm.
3. Now 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.
4. As 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.
5. As you breathe in, slowly go back to the starting position.
6. Repeat for the recommended amount of repetitions.

Form tips

• Start light and own the movement before adding weight.
• Control the lowering phase — don't drop into it.
• Keep breathing; exhale on the hardest part.
• Stop if you feel sharp pain (different from muscle burn).
