Ive been working out for awhile now, and im happy with results in my arms. But when I do ab workouts I never see any results. I feel if I do cardio then all the calories I consume will just burn off and my arms will not get bigger. My stomach expands but no abs appear. My normal calorie consumption is about 5,000 a day. I also take mass peak and carbo gain. So my question is how do I gain abs but not lose mass in my arms?
