As far as I'm concerned, bodybuilding is one of the most fascinating sports of our time. I've often wondered how far we could really go if we had all the right answers. The trouble is, we don't have all the answers-and there are so many approaches to training, it's easy to get
confused. Not only that, but each of us has a different genetic makeup that determines how we react to training. There are a few basic truths though.
The first, informing principle of bodybuilding is this: When your body is subjected to stress, it either adapts or breaks down. The purpose of the ideal program is to subject your body to reasonable stress that will cause it to adapt without causing injury. Although there are obvious differences in how each of us reacts, three factors remain key to developing a physique: duration, intensity and frequency of training.
