Bench Dumbbell Forearm Pronation
In SetGrip: Dumbbell Forearm Pronation (Bench)
Face down on a bench with your arms hanging, rotating the dumbbells palm-down isolates the pronators with your upper arms completely fixed: no elbow drift, no shoulder help. Hold the dumbbell off-center with the pinky near one end and leverage does the loading for you. A five-pound bell is genuinely enough for most lifters starting out.
How to do the Bench Dumbbell Forearm Pronation
- Lie flat on a bench with your chest facing down and your arms extended straight down, holding a dumbbell in each hand.
- Rotate your palms so they are facing up.
- Keeping your upper arms stationary, exhale and curl the dumbbells as you rotate your palms to face down.
- Inhale and slowly lower the dumbbells back to the starting position.
- Repeat for the desired number of repetitions.
Tip: Use high reps, 15 to 25, and a light weight you can move through the full range with control.
Muscles worked
Common mistakes
- Moving the elbow — the forearm should rest on the bench or your thigh and only the hand should turn; if the elbow lifts, you are using the biceps.
- Rushing through the range — go slowly and pause at each end so the small forearm muscles do the work rather than momentum.
- Going too heavy — these movements use small muscles, so a light dumbbell or plate is plenty; the goal is a burn, not a max.
- Bar rolling off the fingertips — on finger curls let it go to the second knuckle and no further, then curl it back into the palm.
Where it fits in a workout
Forearm work goes at the very end of a session after all gripping is done. Superset finger curls with reverse wrist curls.

Variations and alternatives
When to talk to someone
- Chest discomfort, feeling faint or lightheaded, or trouble breathing during or after exercise can be signs of a heart attack. In the US, call 911 right away; elsewhere, call your local emergency number.
- Heart, metabolic or kidney disease, or symptoms like these when you are active: talk to your doctor before you start or step up training.
- Pregnant: ask your obstetric care provider which exercise suits you.
