Very good question which deserves a legit answer.
What's your general condition/bodyfat (not talking percentage). Fatso, a 'lil pudgy, average Joe Shmoe, kinda lean, uber-ripped?

Dude, do yourself a favor: Narrow down specific goals and go even longer before specializing in anything, let alone the most over-used exercises in the fitness world.
