A combination of things goes into his shape... genes, time, money, personal trainer, nutritionist... did I mention time and money.
Visualizing a goal is a pretty good way of trying to achieve that goal... just try to understand where your at in correlation to what it is your trying to achieve. If you need more mass, put on the mass. If your already there musculary, go on the cut. Eat properly, train hard and you'll get "your" best shape.
