For bulking you have two options correct... You could either dirty bulk far past your desired weight and then go on a extended cut to get your BF% back in check. Or you could clean bulk.. ensure your not putting on weight too quickly, keep the calories clean rather than eating everything insight, and maintain a reasonable BF%. With a dirty bulk you definitely feel like your doing more since your putting on a significant amount of weight then cutting back down... rather than taking the time to ensure your putting on quality mass. But either option will probably get you to your goal in the same time ( I would think).. I'd go with a clean bulk myself (currently am on one).. Figured Id rather stay athletic looking, healthier, and it would keep me from developing lazy habit (unhealthy meals, lack of cardio/core training...).
