Description
A dumbbell hammer curl is a bicep exercise that targets the brachialis muscle, which lies underneath the biceps brachii. This exercise also works the brachioradialis, a muscle of the forearm.
How to Do Dumbbell Hammer Curl
- 1Setup
Stand tall with a dumbbell in each hand, arms extended by your sides, palms facing your torso (neutral grip). Maintain a slight bend in your knees and engage your core.
- 2Setup
Keep your elbows tucked close to your body and shoulders pulled slightly back and down, avoiding any shrugging.
- 3
Exhale as you slowly curl both dumbbells upwards towards your shoulders, keeping your palms facing each other throughout the movement. Focus on contracting your brachioradialis and brachialis.
- 4
Continue curling until your forearms are perpendicular to the floor or just below shoulder height, ensuring your upper arms remain stationary.
- 5
Inhale as you slowly lower the dumbbells back to the starting position with control, fully extending your arms without locking your elbows.
Tips
- Maintain a neutral wrist position throughout the entire movement; avoid flexing or extending your wrists to protect your joints.
- Keep your elbows pinned to your sides to isolate the arm muscles and prevent the shoulders from taking over the lift.
- Focus on the eccentric phase, slowly lowering the weight for 2-3 seconds to maximize muscle growth and control.
- Avoid using momentum or swinging the weights; if you can't control the movement, the weight is too heavy for proper form.
Common Mistakes
- ×Swinging the dumbbells using momentum reduces the tension on the target muscles; instead, lower the weight and perform the movement with strict, controlled form.
- ×Flaring elbows out to the sides shifts the focus away from the brachioradialis and brachialis; keep your elbows tucked in close to your torso to maximize isolation.
- ×Not fully extending the arms at the bottom limits the range of motion and muscle activation; ensure a complete stretch at the bottom without locking the elbows.
