How to perform Dumbbell Lying Pronation
- 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.
- Bend the elbows of the arm holding the dumbbell so that it creates a 90-degree angle between the upper arm and the forearm.
- 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.
- 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.
- As you breathe in, slowly go back to the starting position.
- Repeat for the recommended amount of repetitions.
Muscles worked
- Forearms (primary): controls your grip and keeps the wrist steady under load.
Sets & reps by goal
| Goal | Sets × reps | Load | Rest |
|---|---|---|---|
| Strength | 3–5 × 3–5 | Heavy (~85%+) | 2–3 min |
| Hypertrophy | 3–4 × 8–12 | Moderate (~65–75%) | 60–90 s |
| Endurance | 2–3 × 15–20 | Lighter (~50–60%) | 30–45 s |
Pick the row that matches your goal. If you're newer, anchor in the hypertrophy range while you groove the form.
Form tips
- Move slowly and let the wrist travel through its full range instead of bouncing at the ends.
- Each side works on its own, so match the depth and speed of both arms and don't let the stronger side take over.
- Treat every rep the same — a repeatable setup and bar path is what lets you add weight safely over time.
- Breathe out on the effort and in on the return, keeping one steady rhythm across the set.
Common mistakes
- Loading so heavy the wrist collapses instead of moving through a clean range.
- Letting the dumbbells drift apart or clang together at the top instead of controlling the path.
- Chasing weight jumps before the current load feels solid on every rep.
