Ok I just recently joined the gym again about 2 weeks ago and i'm not sure how to split up my routine. i am bulking and usually do upper body and lower body in one day three times a week...so it looks something like:

Bench Press with Barbell X3
Dumbbell Flys X3
Shoulder Press X3
Dumbbell Bicep Curls X3
EZ Bar Curls X3
Tricep Exetensions X3
Chinups X3
Leg Extensions X3
Calf Raises X3

same for wednesday and friday then i rest on saturday and sunday. I know i shouldn't do everything in one day, and I should probably be doing squats but I don't know how to split it up.
