Just wondering how much size I can gain in upper arms (Bi's + Tri's together) in a year? assuming that you are eating enough calories to exceed your BMR+activity level to promote growth, and not over training the muscle groups. assuming that the individual has 1-2 years weight training experiance.
Is 1-2 inches/year about right? more? less?
