Overview
How to do it
- 1
Seated Position
Sit on a bench or chair with your back upright and both feet planted on the floor. This setup steadies your body and helps you isolate the muscles you want to train.
- 2
Supinated Grip
Take a dumbbell in each hand with your palms turned up in a supinated grip. Let your arms hang straight down at your sides to start.
- 3
Curl Phase
Lift the dumbbells toward your shoulders while keeping your upper arms still. As you raise the weights, keep your palms facing up.
- 4
Pronation Phase
When you reach the top and your biceps are fully contracted, rotate your wrists at the top of the movement so your palms turn downward into a pronated grip.
- 5
Return to Starting Position
Lower the dumbbells slowly back to the start while keeping your palms facing down. After your arms are fully extended, turn your wrists back to the palms-up position and repeat for the desired number of repetitions.
Form tips & common mistakes
If the load is too heavy, your form can break down, the dumbbells may swing, and injury risk rises. Pick a weight that lets you move with control and proper technique.
Use slow, controlled reps from start to finish. Keep your upper arms fixed and let your biceps and forearms do the lifting and lowering.
Fully extend your arms at the bottom and squeeze the biceps completely at the top of every rep. That helps maximize muscle engagement.
Stay firmly seated throughout the exercise. Tighten your core to limit extra movement and better isolate the target muscles.
At the top of the curl, rotate your wrists so your palms turn downward into a pronated grip. This helps target the forearms and increases the exercise’s effectiveness.
Give the eccentric, or negative, phase your full attention. Lower the dumbbells slowly and under control, keeping the muscles working through the full range of motion.
Benefits
Seated Zottman Curl is a compound exercise that hits the biceps brachii, brachialis, and forearms at the same time. That broad muscle involvement supports balanced arm development.
A standard bicep curl isolates the biceps well, but the Zottman curl adds the forearm muscles into the mix. That can improve bicep strength, helping you handle heavier weights and perform other upper body exercises.
The pronation phase of the Zottman curl strongly emphasizes the forearm muscles, especially the brachioradialis. Building these muscles supports forearm appearance and also improves grip strength, which matters for many daily activities and sports.
The brachialis often gets less attention in traditional bicep curl exercises, but Zottman curls train it effectively. Developing the brachialis can improve both arm aesthetics and arm strength.

Alternatives & variations
Frequently asked questions
Can beginners do the Seated Zottman Curl?
Yes—start with light weights and focus on form before increasing load.
Is it better seated or standing?
Seated helps reduce momentum, making it better for isolation; standing allows for heavier loads.
How heavy should I go?
Use a weight you can control in both curling and lowering phases without wrist discomfort.
Can this replace regular curls?
It can be included instead of or alongside regular curls for more forearm involvement.
