What is your goal? Strength, martial arts? Joel Jameson recommends two weight lifting work outs a week, hitting big exercises. He also recommends conditioning 2-3times a week if you are not training and work the conditioning with MA drills and what not.
It would help to know the usual stats. Age weight stuff like that. If you are a young buck you can get away with a lot more than some one 40 like me. I have to plan more and sleep more and eat more. If my kids let me.
