Im working out every other day and attempting to do cardio on the days im not lifting. being that im trying to gain some size i want to conserve all the calories i can by not burning them when i can avoid it. i feel if i do cardio im going to loose any size i do have. i know i'm wrong with this but i can use some input as to when is best for cardio. im doing a 5x5 chest/tri back/bi shoulders/legs split. i do this every other day and abs on non lift days. is their a more productive way to split, like lift for 2 days rest for 2 ect. any ideas about cardio and the weekly split would be great. also working on my diet and will be getting around 3500cals which will help with the size thing.
