The conventional body building of bulking in the form of eating as much as you can of whatever you want to put on mass is an absoloute waste of time. A much more efficient method to bulk is to eat 300 calories over your maintainance cals everyday for the first week and add 50 cals to that number every week after for a total of 8 weeks. so week 1: 300 cals above mainatainace, week 2: 350 cals week 3:400 cals above ect. Try to keep the majority of these cals come from breakfast, pre, during, and post workout.
