Yeah u only need 2 movements for biceps. Any more and ur just making it harder to track progress for no benefit
hammer curls for brachioradialis (forearms) not biceps, just do preacher curls/bayesian curls then hammer curls
I do cable curls too
2 movements is enough, make sure one is targeting the short head and one the long head.
tysm omg ive been lied to about hammer curls this whole time omg
Behind the back single arm to accentuate the long head
