Zac--, tell us about your training and nutrition. It looks phenomenal!
Training wise I hit the gym 3-4x a week and make sure to work my ass off in there. Just recently I've started to lift heavier and with lower repetitions as opposed to the higher 10-12 rep range i've incorporated into my routine for almost all of my lifting days.
In the kitchen I make sure to eat anything and everything I can possibly get my hands on. When i'm working i have steak and potatoes, when i'm not working i usually emphasize tuna fish, brown rice, chicken breast, and milk.
