i just want to make sure that i am not over training my shoulders...tell me what you think:

4 sets smith barbell shoulder press (heavy)
3 sets machine shoulder press (medium)
3 sets seated side dumb bell lateral raises
3 sets upright row

i'm sure most of you will say drop the 2nd shoulder press, but i like how it feels after doing heavy barbell, a nice smooth machine press really gets me pumped. rear delts i train on back day.
