Much of this depends on your goals as stated above, but also how frequently you can manage to train in terms of how many days per week can you commit to that one hour? If it's 4-5, you'll, in my opinion, want to give serious consideration to, at the very least, employing an upper/lower split (each half 2x/week). If you can only make 2-3 days, a full body workout may be the way to go (in fact, I think the case against them is largely overly reactionary, particularly as it applies to a beginner or low intermediate). At any rate, you'll want to prioritize exercises that hit as many possible bodyparts as possible for efficiency's sake. Deadlifts, squats, pullups, military presses, bench presses (of all varieties) and rows are all exercises that can be peformed by begginers (and I'd bet most vets of the iron game even wish they started some of these exercises earlier than they did). With some instruction, cleans, barbell hacks, clean and jerk, etc also do wonders for a full body regimen.
