I'm pretty active outside of lifting. I am using Westside for Skinny Bastards part III, so I lift 4x/week. I run interval sprints on the track twice a week, and push the prowler once a week.
I've actually been eating about 4,000cal/day during my bulk. I have a pretty fast metabolism, and combined with the conditioning and lifting, I need a pretty substantial amount of calories to grow. I agree with you 100% though, the added conditioning work certainly helps with minimizing the fat gain.
