I just have quit smoking for about 4 months now and am done working for the summer (landscaper) now I am back to school. I am an ectomorph and have always been slim. I have started my bulking phase and i dont know if its just diet or effect of not smoking but i am starting to get a gut for once. it seems most of the wait i gain is goin to th ebelly but overall mass has improved. How long should i keep up this, I don't want to be to fat. Should I clean up my diet maybe a bit and add maybe 60 mins of cardio a week? thanks
