A neutral, thumbs-up grip on the preacher bench aims the pad's strictness at the brachialis instead of the biceps proper. Since the pad blocks the elbow drive that lets standing hammer curls go heavy, drop the weight meaningfully and let the fixed upper-arm position do its job.
How to do the Dumbbell Hammer Preacher Curl
- Stand up straight with a dumbbell in each hand, palms facing your torso.
- Keep your elbows close to your torso and rotate the palms of your hands until they are facing forward.
- This will be your starting position.
- Now, keeping the upper arms stationary, exhale and curl the weights while contracting your biceps.
- Continue to raise the weights until your biceps are fully contracted and the dumbbells are at shoulder level.
- Hold the contracted position for a brief pause as you squeeze your biceps.
- Then, inhale and slowly begin to lower the dumbbells back to the starting position.
- Repeat for the recommended amount of repetitions.
Tip: Lower for three seconds and stop just short of locking out the elbow to keep the muscle under tension.

Common mistakes
- Elbows drifting forward — as the elbows come up the front delt starts to lift the weight; pin the elbows to your sides and let only the forearm move.
- Swinging from the hips — a small rock backward on each rep means the weight is too heavy; drop it and curl from a dead stop.
- Cutting the bottom short — stopping with the elbow bent shortens the range where the biceps are stretched; lower until the arm is nearly straight.
- Wrists curling at the top — flexing the wrist toward you brings the forearm flexors in; keep the wrist neutral or slightly extended.
Sets, reps and where it fits
| Goal | Sets × reps | Rest |
|---|---|---|
| Muscle growth | 3–4 × 10–15 | 60–90 s |
| Endurance / finisher | 2–3 × 15–20 | 45 s |
| Strength | Not ideal — pick a compound lift for the same muscle | — |
Curls go at the end of a pull session or arm day, after the rows and pulldowns that also load the biceps. Superset them with triceps pushdowns on the same cable stack or triceps extensions with the same dumbbells.
