 Generally speaking, a surplus or a deficit would be in the range of three to 800 calories, I would say. So 300 to 800 calories above where your maintenance is would be your bulk, 300 to 800 calories below where your maintenance is would be a cut. Now, when would I not do this? Well, if your maintenance is so low that cutting you 300 or 400 calories puts you at 1200 calories, I'm not gonna do that. I'm gonna put you on the bulk and do what's called a reverse diet. How do I know if this is the right bulk number? I would gauge it off performance. Here's one of the mistakes people make with a bulk. If you look at the scale, lean body mass doesn't come on very quickly. So if you're gaining two pounds, three pounds a week on the scale, you're probably not gaining muscle. Unless you're a complete beginner, that's not muscle. So it should be pretty slow. Like you should see your weight go up a few pounds a month and have correlating strength gains. That means you're on the right track. Don't make the mistake that I always made in bulks, which was, oh, I'm getting stronger but I only gained three pounds. Let me double my calories, make the scale go up more and then you only get a body fat test and you find, oh, all I did was gain more body fat.
