What is the difference between hammer curls and barbell curls?
Both hammer curls and barbell curls work the biceps brachii muscle, the main difference being the position of the hands and the recruitment of different muscle fibers.
In the hammer curl, the wrists have a neutral grip, that is, the hands are facing inwards, facing each other, while in the barbell curl, the hands are facing upwards.
This allows different muscle fibers to be activated more intensely, with hammer curls focusing on the longer head of the biceps and in barbell curls the shorter head of the biceps. See how to do the barbell curl.
