I have lost about 30 pounds of bodyfat over the past 4 months and have also gotten stronger, but my arm size has decreased about 1 inch. My arm looks bigger and better.. but my clothes fit more loose everywhere and it bothers me that I have gained strenght, but lose size. Since I have reached about 8 to 9 percent bodyfat.. I do not want to gain anymore weight... but I want to add that inch back onto my arms. So can muscle size increase without gaining weight? I do not care if I get stronger or not... just bigger
