The dumbbell Zottman preacher curl combines a preacher-bench curl with the Zottman rotation to train the biceps brachii on the way up and the brachialis, brachioradialis, and wrist flexors on the way down. You curl with palms up (supinated), rotate to palms-down (pronated) at the top, then lower under control. Resting your upper arms on the preacher pad removes momentum, making it a focused single-set builder for the upper arms and forearms.

How to do the Dumbbell Zottman Preacher Curl

  1. 1Sit at a preacher bench and set the pad so the top edge tucks under your armpits, with the back of your upper arms flat against it.
  2. 2Hold a dumbbell in each hand with a supinated (palms-up) grip and let your arms hang almost straight, keeping a slight bend in the elbows.
  3. 3Curl both dumbbells up by flexing your elbows, keeping your upper arms pressed into the pad and your wrists neutral.
  4. 4At the top, pause and rotate your wrists until your palms face down (pronated) into a Zottman position.
  5. 5Lower the dumbbells slowly with the pronated grip, taking 3–4 seconds to reach the bottom while keeping tension on your forearms.
  6. 6At the bottom, rotate your wrists back to palms-up to set up the next rep.
  7. 7Repeat for your target reps, then place the dumbbells down with control.

Form tips

  • Curl up explosively with the supinated grip and lower slowly with the pronated grip — the eccentric is where the forearms and brachialis do most of the work.
  • Keep the rotation smooth and deliberate at the top; rushing the flip lets the dumbbells drop and wastes the eccentric.
  • Use a lighter load than a standard preacher curl, since the pronated lowering phase is the weak link that sets your working weight.
  • Keep the back of your upper arms glued to the pad so the elbows stay fixed and the biceps and forearms do the lifting.

Common mistakes

  • Lowering the pronated phase too fast, which throws away the main forearm and brachialis stimulus the Zottman is built for.
  • Going too heavy, so the wrists buckle during the pronated lowering and strain the wrist flexors.
  • Lifting the elbows off the preacher pad to swing the weight up, which removes tension and turns it into momentum.
  • Rotating the wrists in the middle of the curl instead of at the top, which shortchanges both the supinated lift and the pronated lower.

Frequently asked questions

What muscles does the dumbbell Zottman preacher curl work?

It targets the biceps brachii on the supinated way up, while the brachialis, brachioradialis, and wrist flexors take over during the pronated lowering. The preacher pad isolates the upper arms by removing momentum.

Why do you rotate the wrists at the top?

Rotating to a palms-down (pronated) grip at the top shifts the load to the brachioradialis and forearm flexors for the lowering phase, so one rep trains the biceps concentrically and the forearms eccentrically.

Is the Zottman preacher curl good for beginners?

Yes, with a light weight. The preacher pad removes swinging, so beginners can focus on the wrist rotation and a slow, controlled lower without cheating the rep.

How many sets and reps should I do?

Three to four sets of 8–12 reps works well. Keep the load light enough to control the pronated lowering for the full set.
