I havent trained chest in 3 months, no flat bench for a year.
I recently went on a bulk and prioritised my arms, so i would do biceps and triceps seperately on different workout days. 3 months it took and i think I only gained half an inch to my arms but it was better than nothing.
Arms would be bombed by fewer sets with higher intensity and i made sure i did biceps after a rest day so i would get the maximum benefit. Ive always had weak arms and a strong chest.
I really cant do skull crushers, i dont mind hard work at all but something about my elbow dosent feel right when i perform the exercise. Like a sharp pain.
Btw im not a noob to bodybuilding, been doing this for 2-3 years so i know a fair deal about training.
The chest only needs to come down a little bit, thats all
