Description
The Barbell Hammer Curl is an advanced bicep variation performed with a specially designed neutral-grip (parallel handles) barbell or trap bar, targeting the brachialis and brachioradialis muscles. Unlike the classic supinated curl, the palms face each other (neutral/hammer position), which places minimal stress on the wrists while maximizing brachialis activation. The brachialis muscle lies beneath the biceps, and developing it dramatically increases overall arm thickness. It also supports grip strength and forearm development. A trap bar or a specialized hammer curl bar can be used. When performed regularly, it provides significant improvements in brachialis hypertrophy, arm thickness, and grip strength.
Step-by-Step Instructions
- 1
Grasp the hammer curl bar or trap bar (neutral grip).
- 2
Take a grip with your palms facing each other (neutral/hammer grip).
- 3
Stand upright with your feet shoulder-width apart.
- 4
Start with your arms fully extended and the bar resting in front of your thighs.
- 5
Keep your back straight and pull your shoulders back.
- 6
Engage your core muscles.
- 7
Curl the bar upward by squeezing your brachialis and biceps.
- 8
Maximally contract the muscles at the top position.
- 9
Lower the bar back to the starting position in a controlled manner.
- 10
Keep your upper arms stationary throughout the movement.
Key Points
- ✓Use a neutral grip (palms facing each other).
- ✓Keep the upper arms stationary; only bend at the elbows.
- ✓Keep the wrists neutral and stable.
- ✓Use a full range of motion.
- ✓Squeeze the muscles at the top of the movement.
Common Mistakes
- ✗Swinging the body - using momentum.
- ✗Raising the upper arms forward - breaks isolation.
- ✗Rotating the wrists - defeats the purpose of the hammer curl.
- ✗Lifting too heavy - compromises form.
- ✗Incomplete range of motion - prevents full muscle activation.
Breathing
Exhale as you curl the bar up, and inhale as you lower it.
