Agree, watched a local champ here. It was like spray painting a car before the show. Went from looking like a steer to a great looking figure.

To me the bicep is the second most important item of the arm. First is the Tricep at the Elbow...the one you get with reverse grip pulldowns. A good arm goes to awesome with attention there...most underworked item of the arm imho.

Answering the question....an inch of growth on the arm is no small task. Visually it would be very noticeable at low bodyfat.
