Dumbbell Hammer Curl

Dumbbell hammer curls are a staple arm builder. They hit more of the brachialis and brachioradialis portion of your biceps than regular underhand curls, and therefore a good choice of exercise to develop arm "thickness."


Since you can typically go heavier with hammer curls than with a regular underhand grip, you'll start with these. Try throwing some Fat Gripz on your dumbbells to work your grip and forearms even harder. – Gareth Sapstead

How long has it taken him to get muscles like that and has he done it naturally?

Scott Herman or whatever he is can't do this properly, thanks for the truth.
