Dumbbell Hammer Curls: Build Stronger, Sculpted Arms

The dumbbell hammer curl is a classic and highly effective exercise for building strength and definition in your arms. Unlike traditional bicep curls, this variation engages additional muscles, making it a must-have in any well-rounded arm workout.

In this article, I’ll explore everything you need to know about hammer curls: how to perform them with proper form, the muscles they target, their benefits, and tips to maximize your results.


What Are Dumbbell Hammer Curls?

The dumbbell hammer curl involves holding the dumbbells with a neutral grip (palms facing each other) and curling the weights upward. This grip places unique emphasis on the brachialis, a key muscle located underneath the biceps, while still targeting the biceps themselves. It’s a versatile exercise suitable for beginners and advanced lifters alike.


Bicep Hammer Curl
Targetting more than just the biceps, the Hammer Curl improves grip strength, is joint friendly, and supports functional strength.

Benefits of Hammer Curls

1. Targets More Than Just the Biceps

Hammer curls emphasize the brachialis and forearms, contributing to overall arm thickness and strength.

2. Improves Grip Strength

The neutral grip requires active forearm engagement, which improves grip strength—a critical factor for many exercises and daily activities.

3. Supports Functional Strength

This movement mimics real-life lifting motions, making it a functional exercise for building practical strength.

4. Joint-Friendly Option

The neutral grip reduces strain on the wrists and elbows, making hammer curls a great choice if you experience discomfort with traditional curls.


How to Perform Dumbbell Hammer Curls

Setup:

  1. Stand tall with your feet shoulder-width apart, holding a dumbbell in each hand with your palms facing each other (neutral grip).
  2. Keep your elbows close to your torso and your shoulders relaxed.

Execution:

  1. Exhale and curl the dumbbells upward by bending your elbows. Avoid letting your elbows flare outward.
  2. Squeeze your biceps at the top of the movement, ensuring full contraction.
  3. Inhale as you slowly lower the dumbbells back to the starting position with control.

Tips for Proper Form:

  • Keep Your Core Tight: Engage your core to prevent swaying or arching your back.
  • Move Slowly: Control the weights to maximize muscle activation and minimize momentum.
  • Focus on Range of Motion: Complete each curl through a full range of motion for the best results.

Hammer curls primarily target the brachialis and the biceps brachii.

Muscles Worked

Hammer curls primarily target the brachialis and the biceps brachii. Secondary muscles include:

  • Brachioradialis: Located in the forearm, contributing to grip strength and arm stability.
  • Forearm Flexors: Support the neutral grip and stabilize the wrist.

Common Mistakes to Avoid

1. Using Momentum

Swinging the dumbbells reduces the effectiveness of the exercise and increases the risk of injury. Always focus on slow, controlled movements.

2. Letting Elbows Drift

Your elbows should remain close to your torso to keep the focus on your biceps and brachialis.

3. Lifting Too Heavy

Using a weight that’s too heavy can compromise form and reduce the exercise’s benefits. Start light and increase as you build strength.

Variations and Progressions

1. Simultaneous Hammer Curls

Curl both arms simultaneously instead of alternating between arms for better focus and stability.

2. Seated Hammer Curls

Perform the exercise seated to eliminate any lower body momentum and isolate the arms further.

3. Cable Rope Hammer Curls

Use a rope attachment on a cable machine to add consistent tension throughout the movement.

How to Incorporate Into Your Routine

Hammer curls can be a part of your arm-focused workouts or full-body routines. Here’s an example of how to include them in an arm day:

  1. Barbell Curl – 3 sets of 8-10 reps
  2. Hammer Curl – 3 sets of 10-12 reps
  3. 45 Degree Bicep Curl – 3 sets of 12-15 reps
  4. Reverse Curl – 3 sets of 10-12 reps

Rest 60-90 seconds between sets to maintain intensity.
