yes indeed! Life does that...A LOT!! For good reasons the size of your muscle as a whole could shrink quite easily but the nuclei numbers would remain constant....which are your "real gains" so to speak. I might have mentioned that this is the whole point of before and after tricks on some magazines to advertise sups..they would hire guys who were huge but stopped training for a while. This is also the reason why Muscle gains are actually a long term.investment unlike what most people say "they go to the gym but they will suck again once theystop"

1. why stop?
   and
2. no way..muscle memory
