Dumbbell Zottman Curl
Dumbbell Zottman Curl Video Guide
The Dumbbell Zottman Curl is one of the most effective bicep curls for building both the biceps brachii and the forearm muscles in one movement. Unlike most curl variations, Zottman Curls combine a supinated grip on the way up (similar to traditional curls) with a pronated grip on the way down (like a reverse curl), allowing the exercise to train the biceps and forearms through two different phases. This unique pattern improves grip strength, grip endurance, and balanced arm development that most curl variations can’t achieve on their own.
During the concentric phase, the Zottman Curl trains the long head, short head, and upper-arm muscles using strict elbow flexion. At the top, you rotate your wrists into a pronated grip, turning the eccentric into a controlled reverse dumbbell curl. This slow, deliberate lowering phase heavily activates the forearm extensors and builds serious strength in the lower arm.
The exercise works well in any arm training routine, sitting comfortably alongside hammer curls, barbell curls, preacher curls, pinwheel curls, and incline dumbbell work. Variations like the reverse Zottman Curl, incline Zottman Curl, and seated Zottman Curl let you hit the same muscle groups from different angles. It’s a favourite among lifters wanting bigger biceps, better wrist position, and stronger forearms without needing separate exercises.
How to Perform the Dumbbell Zottman Curl
-
Start in the correct starting position: Stand tall with feet shoulder width apart, dumbbells at your sides, palms facing forward in an underhand grip, elbows locked close to your torso, wrists straight.
-
Concentric phase: Curl the dumbbells slowly, keeping upper arms still to maximise biceps activation and constant tension.
-
Rotate your wrists: At shoulder level, rotate smoothly into a pronated grip so your palms face downward.
-
Eccentric phase: Lower the dumbbells slowly — the controlled pronated lowering phase is the key driver of forearm strength.
-
Reset: At the bottom, turn palms facing forward again and repeat for the desired repetitions.
-
Keep every rep controlled: Avoid swinging, leaning back, or letting the shoulders roll forward.
GymNation Tip: If the rotation becomes a limiting factor, switch temporarily to light dumbbells until you can move through the full range of motion with perfect control.
Personal Trainer Notes:
-
Keep elbows pinned to your ribs; drifting reduces effectiveness.
-
Maintain a neutral shoulder and wrist position; don’t snap the rotation.
-
Use moderate weight — technique beats heavier loads for this curl.
-
Prioritise the lowering phase, where the forearm extensors work hardest.
-
Works perfectly after heavy curls or as a finisher in arm workouts.

Alternative Bicep Exercises
Barbell Curl
The Barbell Curl targets the biceps brachii, helping to build size and strength in the front of your upper arms. It’s a staple for arm development and grip strength. Perform it with control and full range of motion for best results.
Barbell Preacher Curl
The Barbell Preacher Curl isolates the biceps (biceps brachii) and reduces shoulder involvement, making it perfect for focused arm growth. The preacher bench supports strict form and control.
Dumbbell Incline Biceps Curl
The Dumbbell Incline Biceps Curl stretches and strengthens the biceps (biceps brachii) through a longer range of motion. It’s great for improving peak shape and flexibility.
Dumbbell Hammer Curl
The Dumbbell Hammer Curl targets the biceps (brachialis) and forearms (brachioradialis). It builds both arm thickness and grip strength while reducing wrist strain.
Dumbbell Concentration Curl
The Dumbbell Concentration Curl focuses on isolating the biceps (biceps brachii) for maximum contraction and shape. It’s excellent for building definition and mind-muscle connection.
Cable Curl
The Cable Curl targets the biceps (biceps brachii) with constant tension throughout the movement. It’s excellent for controlled strength and shape development.
Dumbbell Standing Biceps Curl
The Dumbbell Standing Biceps Curl targets the biceps (biceps brachii) and forearms (brachioradialis). It helps improve arm symmetry and muscle tone when done with strict form.
EZ Barbell Curl
The EZ Barbell Curl strengthens the biceps (biceps brachii) with reduced wrist strain thanks to the angled grip. It’s ideal for building strength and muscle mass with comfort.
Dumbbell Alternate Biceps Curl
The Dumbbell Alternate Biceps Curl strengthens the biceps (biceps brachii) while improving balance and coordination between arms. Alternating sides allows full focus on each arm.
Dumbbell Zottman Curl FAQs
It works the biceps brachii, brachialis, brachioradialis, and forearm extensors, training both the biceps and forearms in one movement.
Because they combine the strongest curl position (supinated) with the strongest lowering position (pronated), giving balanced arm development and major improvements in grip strength.
For complete arm development, yes. Traditional curls focus on the biceps; Zottman Curls train the biceps and forearms together.
Absolutely. The long eccentric and dual-grip pattern increase time under tension, which boosts muscle growth in both the upper arm and lower arm.
Use weights you can lower slowly. Most lifters go lighter than their regular dumbbell curls due to the pronated lowering phase.
Using momentum, rushing the rotation, bending the wrists, or skipping the eccentric phase.
Yes — start with light dumbbells and learn the rotation before adding more weight.
Reverse curls, hammer curls, pinwheel curls, preacher curls, and cable Zottman curls all hit similar muscle groups.
