We have all this stuff on the web now, but for a total newcomer, I think it's best to start with something concrete; just buy a book.
Not a "you can be huge in six months book" with a picture of some hulk on the cover, but a basic weight training (not bodybuilding) for fitness book which has beginners routines that are not especially long and consist of around three workouts a week, four max. You want something at this point that is about building basic strength, not developing size in particular muscle groups for aesthetics alone. Some hints; the cover will usually have pictures of fit but not huge men or women doing simple exercises with free weights, and the author or authors will have some credentials in medicine, biomechanics, sports training, or whatever.
Go browse a bookstore and pick out one you're comfortable with; you'll have a choice of at least a dozen.
