About cardio

Is cardio important in bodybuilding if YES then how important? Why its is important? And how much cardio workout is done I mean 30 min or 40 min before workout or after workout?
and how many days in a week?

 

Cardio in bodybuilding is used (I think) mostly for cutting, although certain types of resistance -- such as kettle bell swings -- could be considered cardio as well, I think.
