you say you stopped cardio because you have a fast metabolism? at 18%bf that doesnt sound very fast to me imo. i would add in some cardio at least a few times a week for a minimum of 30 to 40 min, not just to burn fat but for cardiovascular also. i would work on cutting down and really watching what you eat to bring your bf down some. it will make you look bigger and its easier to see whats happening with your muscles without a layer of fat surrounding it...
