I'm curious about what you believe to be physiological principles. Say you were a trainer and you had four different clients with different goals. Lay down your theoretical framework for each client's goals:
1. A guy who wants to become as strong as possible. Just so no one b.itches about semantics, by "strong" I mean "able to lift the most weight possible for 1 rep" ie. a powerlifter.
2. A guy who wants to get as huge as possible (bodybuilder).
3. A guy who wants to be able to box for 12 rounds without tiring, run 5 miles without tiring, but doesn't care about adding size.
4. An overweight guy who wants to lose some extra fat and "develop some tone."
A brief exercise and diet overview is all that is necessary.
Ready? Go.
