everything ive been told and read says to get bigger and stronger to eat all the time and eat lean foods which i try to do but i happen to gain weight in my mid section very easily so i do gain muscle and weight but i also gain a little bit of a gut even when i try to do cardio 3 days a week and lift weights 5 days a week. how do i gain lean mass and at the same time get a cut upper body and 6 pack abs?
