Zottman Curl
The Zottman curl combines a standard dumbbell curl on the way up with a reverse curl on the way down, switching your grip at the top of each rep. That combination trains your biceps through the lifting phase and shifts more of the work to your forearms during the lowering phase, covering two training goals in a single exercise. It suits lifters who already curl comfortably and want more complete arm development without adding a second exercise.
Why it works
A standard curl, palms up the whole time, mainly targets your biceps. A reverse curl, palms down the whole time, shifts more of the load onto your forearm muscles, especially the ones that extend your wrist. The Zottman curl gets both: you curl up with your palms facing up like a normal curl, which loads your biceps on the way up, then rotate your wrists at the top so your palms face down and lower the weight slowly in that position, which shifts the lowering phase onto your forearms instead. Rotating back to palms-up at the bottom resets you for the next rep.
Set up
- Hold a dumbbell in each hand at your sides, palms facing forward.
- Stand with your feet shoulder-width apart and your elbows close to your torso.
- Choose a weight lighter than your usual curl weight, since the forearm-dominant lowering phase is the harder part of this exercise.
How to do it
- Curl both dumbbells up toward your shoulders with your palms facing up, keeping your elbows pinned at your sides.
- At the top of the curl, rotate your wrists so your palms now face down.
- Lower the dumbbells slowly and under control in that palms-down position.
- Once your arms are fully extended, rotate your wrists back to palms-up to start the next rep.
- Keep your elbows stationary at your sides through the entire rep.
- Repeat for the full set, controlling the rotation at both the top and bottom.
Form cues
- Elbows stay pinned at your sides, don't let them drift forward.
- Rotate your wrists fully at the top before lowering.
- Lower slower than you curled up; that's the point of this exercise.
- Keep your wrists straight, not bent back, during the pronated lowering phase.
Breathing: Exhale as you curl the dumbbells up, inhale as you lower them through the pronated grip.
Common mistakes
Rushing the lowering phase instead of controlling it.
Fix: Slow the lowering phase down deliberately; that pronated descent is the main reason to do this exercise over a regular curl.
Letting the elbows swing forward to help lift the weight.
Fix: Keep your elbows pinned at your sides and drop the weight if you can't curl without swinging them.
Bending the wrist back during the pronated lowering phase instead of keeping it straight.
Fix: Keep a straight line from your forearm through your wrist as you lower; a bent wrist here shifts stress onto the joint instead of the forearm muscle.
How to program it
- Three sets of 8 to 12 reps works well, using a weight noticeably lighter than your regular curl, since the slow pronated lowering fatigues your forearms faster than a normal curl's lowering phase.
- Two sessions a week is a reasonable frequency for an isolation exercise like this one, especially if your forearms are already getting indirect work from pulling exercises earlier in the week.
- Place it after your main pulling or curling work for the session, since pre-fatiguing your forearms here will limit your grip on anything heavier that follows.
- Increase the weight only once you can control the full pronated lowering phase on every rep; a faster drop at a heavier weight defeats the purpose of the exercise.
Safety notes
- Keep your wrists straight rather than bent back during the pronated lowering phase to avoid loading the wrist joint instead of the forearm.
- Use a lighter weight than your regular curl until you know how your forearms respond to the slow lowering phase.
- Stop if you feel sharp pain in your wrist or elbow rather than the expected forearm fatigue.

Frequently asked questions
How many sets of Zottman curls should I do?
Three sets of 8 to 12 reps, using a weight lighter than your regular curl, is a solid starting point.
What's the difference between a Zottman curl and a regular curl?
A regular curl keeps your palms facing up through the whole rep. A Zottman curl adds a wrist rotation at the top so you lower the weight with your palms facing down, which shifts more of the lowering work onto your forearms.
Can I do Zottman curls without dumbbells?
You need a handheld weight that can rotate independently in each hand for the grip switch to work, so dumbbells are really the standard tool here; a barbell can't rotate the same way in each hand on its own.
Why do my forearms feel this more than my biceps?
That's expected. The slow, palms-down lowering phase is specifically designed to load your forearms more than a standard curl does, so forearm fatigue showing up first is the exercise working as intended.
