The best method is long distance cardio with a low protein diet. If your sweat smells like urine (it is the ammonia byproduct caused by the breaking down of proteins once the carbohydrates are depleted). Also size is not so much of an issue as how your muscles are shaped. My calves are 16.5 inches flexed but look like they are 12-13 inches since most of the mass is on the inside and the muscles are elongated.
