Okay so I've planned a diet from 3J's post and I'm to have roughly 4200 calories a day. I currently weigh only 157lbs and I'm really wanting to bulk! The only dilemma is that sometimes i have to work 5-10 hours straight sometimes with minimal break. This makes it extremely hard getting in calories when I work. Does anyone have any good ideas or foods which are calorie dense so I can still hit my calorie target to bulk? I should add that I used to weigh 167lbs but had a break from the gym for a few months
