Why do Zottman curls instead of regular curls?

Zottman curls train both the biceps and forearms in one exercise by combining a supinated curl with a pronated lowering phase. This makes them more time-efficient for building overall arm strength and size compared to doing biceps and forearm exercises separately.

Should I use lighter weight for Zottman curls?

Yes, you will typically need to use 10 to 20 percent less weight than standard biceps curls because the pronated lowering phase is limited by forearm strength. Choose a weight that allows you to control the eccentric portion without losing form.

Can I do Zottman curls seated?

Yes, seated Zottman curls work well and can help reduce the temptation to use momentum from your legs or hips. The movement pattern and wrist rotation remain the same whether seated or standing.

Zottman Curl (Dumbbell)

The Zottman curl is a dumbbell curl variation that trains both the biceps during the lifting phase and the forearms during the lowering phase by rotating the wrists at the top of each rep. It suits lifters who want to build arm size and grip strength efficiently in a single movement.

Muscle group: Biceps
Primary muscles: biceps, forearms
Equipment: Dumbbell

How to do the Zottman Curl (Dumbbell)

Stand with feet shoulder-width apart, holding a dumbbell in each hand with palms facing forward.
Curl the dumbbells up toward your shoulders while keeping your elbows stationary at your sides.
At the top of the curl, rotate your wrists so your palms face downward.
Lower the dumbbells slowly in this pronated position, emphasizing control through the forearms.
At the bottom, rotate your wrists back to palms facing forward and repeat.

Form tips

Keep your elbows pinned to your sides throughout the entire movement to isolate the biceps and forearms.
Rotate your wrists deliberately at the top rather than flipping them quickly to maintain tension.
Lower the weight slower than you lift it to maximize forearm engagement during the eccentric phase.

Common mistakes

Swinging the torso or using momentum to lift the weight reduces biceps activation and increases injury risk.
Rotating the wrists too early during the curl shifts tension away from the biceps before they complete their contraction.
Lowering the weight too quickly in the pronated position wastes the forearm-building benefit of the eccentric phase.

Sets and reps

For hypertrophy, perform 3 to 4 sets of 8 to 12 reps, and for strength with an emphasis on grip, use 3 to 5 sets of 5 to 8 reps with heavier weight.
