barbell curl and hammer curl?

Could anyone tell me what the difference is??
thnx

Barbell curl uses a bar and are just typical curls with your palms facing the ceiling... hammer curls are done with dumbbells and you keep your palms facing toward each other during the entire curl motion. Hope that helps.

Works your biceps at different angles. I'm fairly sure that hammer curls work your brachialis more and brachioradialis which is basically your lower bicep and forearm.

Hammercurls are also a great way to train your forearms, Brachioradialis - the muscle that goes along the inner side of your forearm to the wrist of your hand.

Synergists when doing Hammercurls are also, Brachialis and Biceps Brachii.

Btw I´d recommend doing more barbell curls than hammercurls if u want to make your biceps grow bigger and better. But include Hammercurls for fun and variation. ;)
