Here is my workout, it covers 5 days:

tues: back
wed:legs
thurs:shoulders,traps,abs
fri:arms

sun:rest
If you want to prioritize your chest here is a five day workout that I use to use and it worked well for me:
mon-chest/bi's/abs
tues-back/tri's
wed-legs
thurs-shoulders/traps/abs
fri-chest(ligth weight high reps, 12-20, lower volume than your
mon. w/o, just try and get a good pump)
sat-rest
sun-rest
