Okay, i’m 20 years old and im 5′8 138lbs.. i’ve been going to the gym religiously since about january and i’ve noticed some muscle mass building but not a lot. I’ve not really been dieting persay, just watching what I eat. I need some advice like a diet plan or suggestions on what to eat so that I can buld muscle.People always suggest a high protein diet, but I dont want to gain weight and i feel like eating a high protein diet will make me gain weight and not lose some of my fat. I dont want to be a body builder or anything, but I would like my abs and arms to be muscular. Also if you have some suggestions for my workout routine that would be awesome!
