i am 5'8 164lbs and 12% BF - i am currently cutting - I have never tried to gain mass before - and i have a couple of questions - when i decide to bulk i know i going to gain some fat back - hopefully minimal - how long should i bulk for? should bulk for 10 weeks then cut for 10 weeks and keep doing that cycle or bulk through the fall and winter and then cut 10 weeks before summer? i just dont want to gain too much fat back - also - how much cardio should be done while bulking? somebody please help me out.
