Very hard to do this, I worked for a masonry company as a laborer throughout college and I would bring protein shakes and oats for lunch and all of the rest of the crew would make fun of me, telling me to eat a whopper have a cigarette lol...and on top of it, their goal was to make me work so hard so that I couldn't workout after work, just to bust my balls. Impossible to eat every 2 hours when doing this type of work, especially the company I worked for...our lunch breaks were only 25 minutes, then back to work, but I tell you my forearms and shoulders, were never stronger, bigger, and more ripped then when I did this type of work, it's lifting for 8-10 hrs a day.
