my arms and delts are very lacking compared to the rest of my body - at least in my eyes. i work my arms twice a week 2-3 excercises at 5 sets with the last to failure. i work my delts once a week hit an exercise for each head @ 5 sets apiece - the last also being to failure. i am not sure how to bring up my bis/tris and delts w/o added excessively to my diet (currently cutting). i dunno if it's my training or what, but if anyone has any ideas i'd love to hear them.
