Totally depends on what you want to do. Most important thing is diet...i can't stress that enough. You have to eat rather healthy or you'll be pissing in the wind.

I usually work out 5x a week for about an hour. I'll do 1 body part a day for those 5 days. It'll look something like this

1. Chest: (Flat bench, incline bench, decline bench, flies "4 sets each")
2. Back: (Wide grip pull-ups, cable pull downs, bent over rows, seated rows)
3. Legs: (Leg press, leg curls, squats, calf raises)
4. Arms: (Tricep cable extensions, skull crushers, overhead dumbell extensions, and a few other excersizes. Then i'll just pump the biceps with some curls and top it off with forearm excersizes)
5. Shoulders: (Military press, upright rows, dumbell press, dumbell arm raises, shoulder shruggs)

During my workout (depending upon how i feel, i'll toss in push ups and sit ups)

Also, will spend between 30 - 40 minutes on the tread mill later in the day for at least 3x a week. I'm doing about 3 1/2 miles at a good pace. Then i'll walk a bit backwards for a different hit on the muscles)

All in all, you don't have to spend a terrible amount of time working out. If you can set aside an average of 6-8 hours a week, you're doing fine.
