I agree with Stacy: much of "bulking" is genetic.
It also depends on how you eat. If you train heavy and eat more, you will grow muscle. If you train heavy and don't eat more, then you will tend to get firm and lose fat, but you won't build as much.
If you are the type who bulks easily, then you may want to stick with mostly total body, moderate=weight workouts like PH or ME, or with weight/cardio combos (when bodybuilders are looking to build muscle, they often reduce their cardio), like Circuit Max.
