Maybe -aj- or some of the other getbig elders can chime in. I have noticed that my triceps are not as full as they once were and have been working out pretty regularly for the last four months or so. They just don't seem to be responding the way the other muscles are this go around. Is this a beginning sign of atrophy, am I overcompensating with another muscle group, is it all in my head? I've added about an inch cold to my arms so I know they've responded, but I'm nervous I may have contracted ARTA.
