Biceps are lacking

[PC650]

my biceps started growing when i started using starigt bar curls with the last two sets too failure with force reps. seems like tri's are alot easier too build than biceps. i keep my range from 8-10

[POPS]

big bar curls all the way for sets of 6-8, last set to failure. Then Ill knock out some alt.dumbells with a moderate weight at slow tempo to finish....my.02..

agreed straight bar worked for me too
