well, it depends on what kind of split you are using. If using a 4 day, I've always had success with this:
Seated Db press: 4x12,10,8,6
seated db lateral raise 3x12,10,8
db reverse flys 3x12,10,8
If you so choose you can also work your traps with your shoulders. You would just add 4 sets of shrugs. I recommend you work your shoulders at a minimum of 48 hours after your chest. A split like chest/biceps monday, legs tuesday, wendsday rest, thursday shoulders/tricep, friday back/calves, would work.
