you can do, some times i train them together, because i feel that they get a sort of work out any way when i train my rear delts. sum times though i just hit shoulders as there quite big! up 2 u mate
When training back im totally wasted by the time im done, i prefer to do traps after shoulders whilst my grip is fresh so i can pile on the plates when doing shrugs from behind and from the front with a bar from a power rack
See (PHOTO SECTION) critique my physique.
HAVE A GOAL IN MIND, AIM FOR IT... AND ACHIEVE IT!
i used to train traps after shoulders but felt i couldnt get full range ov movement due to them already being pumped from the shoulder workout so i now do traps after chest and my traps really get a proper workout and ache the nxt day so its defo working at mo.
