Work the back hard, biceps grow for free. Barbell rows, pull ups, lat pulls all done with full range of motion, no cheating/swinging and slow negatives.
OP...please don't be one of those guys that does nothing but biceps
you need a solid base before doing specific bicep exercises... and we're talking at least a year...
there used to be a guy who came into the gym - and always with a mate who he'd be showing how he did it.. .and all I ever saw him do was bicep curls with weights too heavy for him and dips...he had no muscle anywhere else...
