Hallowed gets the privilege of spelling it without the "z", but the reason why IS that deepest, darkest secret you asked about. LOL
Training has always been pretty simple for me:
Lift as heavy as possible, while controlling the weight. I've always kind of had a Tom Platz approach to things. It's not about high reps with light weights or low reps with heavy weights, but high reps with high weights. I might only do 3-5 reps a set, but I may do 10 or 15 sets of that. I have never purposely done a max rep on any lift.
I get in and get out. I have never had the desire to spend more than an hour in the weightroom and prefer keeping it less than 45 mins. Plus, setting a time limit keeps you focused on the task at hand. I could never understand spending 2 and 3 hours to accomplish something you can do in less than half the time.
As far as eating, I have been at this so long, I eat when I am hungry. I just "know" when i need to eat. Some days that may mean I eat 8 or 9 times. Other days it may be only once or twice. Either way, I tend to eat a lot more than the average person. When working on getting lean, I was already doing something similar to CT's Pulse Fast. Truthfully, a LOT of the techniques and training philosophies that are on here, I either figured out or learned from someone more experienced before they ever popped up on here. It's just that the authors on here actually researched and studied this stuff to figure out WHY it works and guys like me know it does, so we just did it without really wondering about the why.
EDIT: The way I eat is not for newbies looking to put on mass. Eat everything that's not nailed down and eat constantly. You should be sick and tired of eating when you go to bed. And PLEASE eat some food that has fat in it. I get so sick and tired of 130 lb guys saying they are bulking and that there diet consists of brown rice, broccoli and chicken breasts. Stop worrying about your abs. You can't see those through a shirt, anyway. What everyone can see through a shirt and what signifies you lift weights is traps and shoulders and depending on the shirt, your arms.
