you'll have to change up your routine since db's are going to be really hard on your secondary muscles. DB bench hurts my triceps the next day.
M - chest / triceps
dumbell bench
dumbell incline bench
dumbell flyes
dips
tricep (lay down on ground, do underhand, overhand, and straight up and down grips and basically do skullcrushers - 3 heads, three grips)
T - back / biceps
pull ups
chin ups
deadlift (with DB's its a suitcase deadlift)
bent over rows
DB curls
pinwheel curls
W - shoulders
DB press
front delt raises
side delt raises
face down, rear delt raises
throw in a set of squats holding the weight up to your shoulders like you were going to do an arnold press. squats = upper body mass.
Th - chest / tri's
F - back / bi's
that should work till sept. one thing you might want to try if you are doing strength / mass is to do 4 sets of 6 (strength style). the next time you work out, do as many as you can with the same weight - 7,8 reps, etc. once you get up to 10 reps (8-10 reps is a mass workout), add some weight and go back down to 6 reps. i think this is an ideal way of doing strength and mass in a workout. especially since you're always going up in weight or reps every week - nice ego boost.
i'm not quite at 100% right now. guys, speak and tell me what i'm missing.
