Clean bulking versus dirty bulking. I think the question really is, are we muscle building or are we fat building? You often hear people say when they're putting on muscle or they're trying to bulk up, that they're going to bulk up and then they're going to rip down. In fact, I even have a lot of clients and others who will ask me, they'll tell me they're afraid to put on muscle, because they're afraid that the muscle, if they stop working out, it's going to turn to fat.
Muscle doesn't turn to fat. A lion can't turn into a giraffe. An apple can't turn into a banana. They're two completely different compositions in your body. I think what's extremely important is to understand that no one, I think, wants to put on muscle at the expense of even gaining excess body fat. It's ultimately going to slow down your muscle building process.
Your goal should be to have clean calories throughout the day, and to put on lean tissue and hold back your body's growth in adipose fat tissue. And the way you do that is by making sure that your foods are healthy foods.
I know some people, when they think about dirty bulking it just really gives them a license to eat pretty much anything they want. They'll spend their days eating, wolfing down cheeseburgers and pizza. That's only not going to give you the nutrition you need to build muscle, but it's also going to put a lot of adipose fat tissue in your body that you're going to have to lose ultimately. Most people don't only want to be muscular and maybe big, but they also want to have that muscularity be vascular and well conditioned.
You want to make sure that you're having clean calories, lean proteins, complex carbohydrates, smart fats. Stay away from hydrogenated trans fats and so on. You'll be sure that if you follow clean eating, spacing your meals properly, you'll be able to clean bulk which is put on lean tissue without putting on a whole lot of fat at the same time, which is what everybody wants.
