Generally speaking, for a non-professional body builder or athlete, if you want growth, you should work it hard, aim for 6-10 reps for 3 sets through a multi-joint exercise (lat pull-downs, curl ups, rows) and then give it 48 hours to recover. So every other day you could work a muscle group if you work it hard enough.
