I've always been under the impression that this game (whether bulking or cutting) is 99% diet. OK, maybe 75%, coupled with rest and training. Question is, is it feasible that you could bulk cleanly and keep fasted am cardio 6-7 days a week for 30 minutes while cranking your calories up to the 4,000 mark and then when it's time to shed the pounds, cardio wouldn't change, but you'd drop your cals by 500-1,000?
