Not knowing your current level of muscularity, and how that compares directly to your desired outcome, my advice is actually to train like you want to get huge, and then start changing things once you're at the point where you don't want more muscle on your frame. It generally takes years of intentional effort (both in the gym and outside of the gym) to end up looking anything like the Rock. I've been strength training for a decade and am still a skinny bastard, so, anecdotally, I'm inclined to suggest that you won't get bigger than you want by accident. But yeah, build the muscle that you do want (and what better way to do that than to train like you want to build muscle?), then adjust things once you're happy with the amount of muscle you've got and start focusing on culling any excess fat.
