i never train shoulders, geneticaly always have awesome shoulders that grow from just incline presses and wide rows
as fior arms, i dotn train biceps purely becoz they never grow and realisticaly as a powerliftier bicep arent really that important
as for triceps i was going to wait until i get back on a blast as my recovery rate isnt impressive atm, and focus on on floor presses and rack lockouts (im sure these will strengthen my shoulders aswell) wen im blasting
