Description
An exercise that targets the biceps and forearms by lifting dumbbells with palms parallel to each other using an arm blaster for support and isolation.
How to Do Dumbbell Hammer Curls (with arm blaster)
- 1Setup
Secure the arm blaster around your neck, ensuring it rests comfortably against your upper abdomen and allows your elbows to tuck into the pads.
- 2Setup
Hold a dumbbell in each hand with a neutral grip (palms facing each other), letting your arms hang fully extended with elbows resting firmly on the arm blaster pads.
- 3
Exhale and slowly curl both dumbbells upwards by flexing only at your elbows, keeping your wrists neutral and forearms pressed against the blaster.
- 4
Continue curling until the dumbbells are near your shoulders, squeezing your forearms and biceps at the peak contraction.
- 5
Inhale and slowly lower the dumbbells back to the starting position with controlled movement, maintaining tension throughout the descent.
Tips
- Focus on squeezing the dumbbells throughout the entire movement to maximize forearm activation and grip strength.
- Keep your elbows locked into the arm blaster pads; avoid lifting them off the pads to maintain strict isolation of the target muscles.
- Control the eccentric (lowering) phase for 2-3 seconds to enhance muscle growth and minimize momentum.
- Maintain a neutral wrist position throughout the curl to prevent strain and effectively target the brachioradialis.
Common Mistakes
- ×Swinging the dumbbells using momentum reduces muscle isolation; instead, use a lighter weight and focus on strict, controlled repetitions.
- ×Lifting your elbows off the arm blaster pads disengages the targeted muscles; ensure your elbows remain firmly pressed into the pads throughout the entire range of motion.
- ×Rounding the back or shrugging the shoulders takes tension away from the forearms and biceps; keep your chest up, shoulders back, and core engaged.
