I think if you maintain your conditioning throughout the year then it's somewhat of a moot point.
My fiancée sees a professional strength coach and she's been assigned 20 minutes of high intensity cardio even on days she lifts. I think there are probably some similarities in the mindsets there. And, from a personal standpoint, I have a lot of friends who lift regularly and are a lot stronger than me. But, if you put us in high intensity cardio situations, they struggle a lot to keep up with me. You need to treat both equally or at least take your conditioning as serious as you take your lifting.
