Weird question, I know. But since becoming a CNA I've definitely developed arm and shoulder muscles. My stomach seems bigger too, underneath the little bit of chub I have. I wonder if that means I've built muscle there or if I just need to lay off the chocolate (ok I know I need to lay off the chocolate anyway ). I was wondering if anyone else has noticed a similar change. I do use my abs a lot when lifting because I know that's supposed to help support your back but maybe I've been doing it wrong.
