I know one time I made great gains, and I was natural, was one off season when I played football in college. I was only eating 4 times a day, not huge meals, but pretty good sized meals. I was running 6 days a week for at least 2 hours a day (running stairs, hills, 40, 100, 200 yard sprints, agility drills) and training 5 days a week and I gained about 10-15lbs that summer and was much leaner than when I had started. I went from about 190 to 205 and LEAN. I was thinking about this once before too diezel, because looking back at that experience, I also wondered if all that food was necessary. Also, I did eat one meal just carbs...lol...after running I would eat pasta. I would never do that now, but shit, I was alot leaner then.
