I need some helping finalizing it however and any input would be great to help. I'm satisified with these exercises, but if any exercises would be better to help gain mass, I am open to them..

One other question I have is.. should I add additional exercies if I'm only hitting each muscle once a week? For example, should I add flat dumbbell press to my chest workout?

Thanks!

Where's the deadlift? I'm of the opinion that it's the second most important mass gaining excersise behind the squat.

I have never done dead lift before, so I'm not very familiar with it, I would like to add it to my routine however.. Would I add it to my back day?
