I'm happy with all my other areas and workout routines except biceps.
My bicep routine consists of:
-Warm-up w/ 21's
-Barbell curl 8, 6, 4
-Preacher curl 8, 6, 4
-Seated incline db curls 8, 6, 4
I think i need to switch it up because i can't get my bi's to grow. What is a good bicep routine that will make them grow? Also should I be doing wide or close grip?
