Seated Dumbbell Hammer Curls

Discover the potential of seated dumbbell hammer curls! This exercise not only strengthens and defines your biceps but also offers numerous benefits. In this guide, we’ll explore the technique, variations, and the wide-ranging advantages of seated dumbbell hammer curls. Elevate your workout routine with these insights!

What are Seated Dumbbell Hammer Curls?

Seated dumbbell hammer curls are a variation of traditional bicep curls that specifically target the biceps brachii muscle. This exercise involves holding a pair of dumbbells with a neutral grip (palms facing each other) while sitting on a bench or chair.

The motion resembles the movement of a hammer, hence the name “hammer curls.” This exercise engages both the biceps and the brachialis muscle, resulting in overall arm development.

Understanding the importance of bicep training

Seated dumbbell hammer curls offer unique advantages when it comes to bicep development. By using a neutral grip, this exercise places less stress on the wrists and elbows compared to other curl variations.

It also targets the brachialis muscle, which lies underneath the biceps brachii, resulting in enhanced arm thickness and symmetry. Incorporating hammer curls into your workout routine can help you achieve well-rounded bicep development.

How to Perform the Seated Dumbbell Hammer Curls

To perform seated dumbbell hammer curls correctly, follow the steps below:

Guide to Seated Dumbbell Hammer Curls: Forms and Benefits

A. Proper Set-Up and Equipment Selection

  • Sit on a bench or chair with your back straight and feet flat on the floor.

  • Hold the dumbbells with a neutral grip, palms facing each other.

B. Step-by-Step Execution Guide

  • Start with your arms fully extended, hanging by your sides.
  • Keep your elbows close to your body and engage your core for stability.
  • Slowly lift the dumbbells while exhaling until your forearms are perpendicular to the ground.
  • Squeeze your biceps at the top of the movement and hold for a brief moment.
  • Lower the dumbbells back down to the starting position in a controlled manner while inhaling.
  • Repeat for the desired number of repetitions.

C. Breathing Technique for Optimal Performance

  • Exhale as you lift the dumbbells and contract your biceps.
  • Inhale as you lower the dumbbells back down to the starting position.
  • Maintain a steady and controlled breathing rhythm throughout the exercise.

D. Recommended Repetition Ranges and Sets

  • Beginners: Start with 2-3 sets of 10-12 repetitions.
  • Intermediate: Perform 3-4 sets of 8-10 repetitions.
  • Advanced: Aim for 4-5 sets of 6-8 repetitions.

Variations of Seated Dumbbell Hammer Curls

To add variety to your bicep workout and stimulate muscle growth, consider incorporating the following variations of seated dumbbell hammer curls:

Alternating Seated Hammer Curls

  1. Technique and Execution:
    • Sit on a bench with dumbbells in each hand, palms facing inward (neutral grip).
    • Curl one arm at a time, bringing the dumbbell towards the shoulder while keeping the other arm fully extended.
    • Alternate between arms.
  2. Benefits
    • This variation adds challenge and complexity to the exercise, targeting the biceps while also improving stability and coordination.

Seated Hammer Curls with Resistance Bands

  1. Proper Form and Execution:
    • Sit on a bench with resistance bands attached to the dumbbells.
    • Secure the bands under your feet or around the bench.
    • Maintain a neutral grip and curl the dumbbells towards your shoulders.
  2. Benefits:
    • By adding resistance bands, this variation provides variable resistance throughout the entire range of motion, intensifying the exercise and promoting greater muscle activation and growth.

Preacher Bench Seated Hammer Curls

  1. Proper Form and Execution:
    • Sit on a preacher bench with your upper arms resting on the angled pad.
    • Hold the dumbbells with a neutral grip and curl them towards your shoulders, focusing on the biceps.
    • Keep your back against the bench for stability.
  2. Benefits:
    • Performing seated hammer curls on a preacher bench isolates the biceps, reducing the involvement of other muscles.
    • This variation allows for a more targeted bicep workout, enhancing muscle engagement and promoting strength and size gains.

Incline Bench Seated Hammer Curls

Technique and Execution:

  • Adjust the bench to a 45-degree incline.
  • Sit on the bench with dumbbells in each hand, palms facing inward.
  • Curl the dumbbells towards your shoulders while maintaining a neutral grip.


  • The incline bench position shifts the emphasis to the long head of the biceps brachii.
  • This variation provides a unique stimulus for growth and development in the biceps, contributing to a well-rounded arm appearance.

Cross-Body Seated Hammer Curls

Technique and Execution:

  • Sit on a bench with dumbbells in each hand, palms facing inward.
  • Curl one arm across your body towards the opposite shoulder while keeping the other arm extended.
  • Alternate between arms.


  • By curling the dumbbells across your body, this variation engages the biceps brachii from a different angle, promoting overall arm development and adding variety to your bicep workout routine.

Note: All of these variations primarily target the biceps brachii, with secondary involvement of the brachialis and brachioradialis muscles. These exercises contribute to bicep strength, size, and overall arm aesthetics.

Common Mistakes to Avoid

To maximize the effectiveness of seated dumbbell hammer curls and prevent injuries, avoid the following common mistakes:

Using Excessive Weight

  • Mistake: Choosing weights that are too heavy, compromising form.
  • Consequence: Increased strain on joints, potential for injuries.
  • Solution: Select a weight that allows for proper form and technique.

Swinging or Cheating Repetitions

  • Mistake: Using momentum or swinging the body to lift the weights.
  • Consequence: Reduced effectiveness of the exercise, less engagement of biceps.
  • Solution: Focus on controlled and deliberate movements.

Incomplete Range of Motion

  • Mistake: Not fully extending the arms at the bottom of each repetition.
  • Consequence: Limited activation of targeted muscles.
  • Solution: Lower the dumbbells all the way down and fully extend the arms.

Neglecting the Eccentric (Negative) Phase

  • Mistake: Not controlling the descent of the dumbbells.
  • Consequence: Missed opportunity for muscle activation and growth.
  • Solution: Focus on the muscle contraction during the negative phase.

Failing to Stabilize the Core and Upper Body

  • Mistake: Leaning or twisting excessively during the exercise.
  • Consequence: Shifted focus away from biceps, increased risk of injury.
  • Solution: Maintain a stable core and upper body throughout the movement.
