I train since 2003.
First year was devoted to get in shape (i was really overweight) than i focused on strenght training.
In that period i really don't care of proportions or other BBesc stuff:
traps,calves, forearms, abs aren't directly trained.
In the last year i switch to a more BBesc style of training.. so i started to be devoted to a more complete training style:
i have added direct abs work. I also train my forearms (once every 2weeks, cause i still use heavy compound lift and my forearms are quite good) and calves work (every week during leg sessions.)
I also added direct traps training when i don't do DL.
By now i try to train every body parts. Styll my triceps need more size....(a lot more size).
