Had a great Bicep workout today , here is the routine I did.

ALTERNATING DUMBELL CURLS 4sets(this routine is more for definition and shape rather than size)

Pick a weight that allows you to get 20 reps (10 per arm) sets 1,2,3 are 20 reps with this weight.

Set 4 use the same weight keep curling until you can not get another rep

Barbell Curls 3 Sets (make sure to use good form no cheating with the lower back or shoulders)

set 1 use a weight that causes failure after 10-12 reps

Set 2 use a weight that causes failure after 8-10 reps

set 3 pick a weight that is heavy enough that you only get 4 -6 reps with good form.

Machine curls 4 sets (pick your favorite curl machine or you can use the cable machine if you like)

set 1 20reps

set 2 20 reps

Set3 lower the weight and do 30 reps

set 30 reps
