Exercise technique

dumbbell hammer curls (with arm blaster)

The dumbbell hammer curl with arm blaster is an isolation exercise targeting the biceps and forearms. The arm blaster helps maintain proper form by preventing the elbows from moving forward, increasing biceps activation.

How do you perform this exercise?

  1. Stand up straight with a dumbbell in each hand, palms facing your torso.
  2. Keep your elbows close to your torso and rotate the palms of your hands until they are facing forward.
  3. This will be your starting position.
  4. Now, while holding your upper arm stationary, exhale and curl the weights while contracting your biceps.
  5. Continue to raise the weights until your biceps are fully contracted and the dumbbells are at shoulder level.
  6. Hold the contracted position for a brief pause as you squeeze your biceps.
  7. Then, inhale and slowly begin to lower the dumbbells back to the starting position.
  8. Repeat for the recommended amount of repetitions.
